Abstract:

This report presents the design and implementation of a novel electronic name card device that makes use

of an 80XX microprocessor emulator. In addition of a micro processor, this device implements the use of a 4 level

gray-scale graphical LCD, a IR transceiver module, as well as a FRAM external memory component that allows non-

volatile data storage of up to 1000+ contact users. As a whole, the system has been oriented towards meeting three

specific purposes; Contact storage/browsing, Contact information exchange, and Innovative Presentation of

Credentials.

Introduction:

The aim of this project is to digitize the paper based name card on a standalone system controlled by a

single micro controller. The project will be geared toward meeting four requirements on functionality; presenting

ones personal information, sending and receiving contact data, presenting a visually attractive screen saver, and

present a contact book that allows users to browse though their stored contacts. We will be using a graphical LCD

display by TOPWAY that allows a 128 x 96 pixel resolution each allowing a 4 level gray scale state. In addition we will

make use of a 24MHz 8xC51 with 4K ROM. Each function will be handled separately in the software domain with a

simple 3 button user interface that will allow of simple and efficient navigation. To allow the device user to save new

users we will use non-volatile external memory space that should efficiently store each users contact package as a

stack which can easily be addressed by the contact book function. Another important aspect of this project is the

protocol used for the transmission of IR data signals between two devices that allow for reliable data transmission

without being prone to error. Each of the before mentioned aspects will be carefully considered in both hardware

and software design and we will aim for a design that is optimal in minimized hardware resources (cost) and

maximized in functionality (value).

The basis of our system consists of a main menu platform that will run after system initialization and allow

simply handle the user interaction to choose what kind of task should be scheduled next. From this platform we will

call functions that will run and after completion will return to its original state waiting for the user to queue the next

processing task. This assures us that the RAM data segment will not get corrupt easily since it avoids the nesting of

multiple functions and therefore allows one to dedicate RAM to a particular function.

The proposed platform is a very generic and simple approach to user interfaces; Present the User with

options, wait for a selection, continue in accordance to selection. In principle this easily allows for a top down

method and should allow us to design each function independently which will improve out efficiency by allowingmembers to work on multiple functions simultaneously without conflict given that the data structure is well

organized and each program has well defined dedicated memory spaces that cannot be altered during the execution

of that program. The trade off by simplifying the design in such an extent is that some program functionality might

be duplicated in different forms. For example one function requires a string to be printed from the ROM while

another function requires a string to be printed from the RAM, clearly both programs will almost implement the

same functionality but because of the independent development it will result in near duplication of code

fortunately we prefer swift development over high quality source code since it will allow us to implement much

more functionality in a limited period of time.

Principles of operation:

The device operation is very simplistic from a user point of view. We simply on start up procedure and 4

states in which the user can interact with the device after power on. Each state is intuitive and listed below

together with a brief description

1. Start up - The start and welcome message will be display every time the system restarts.2. Main menu mode - The main menu includes the 4 major selections, display info, infrared, screen saver

and contact book. After the welcome message or transmission, the program will return to main menu.

3. Screen saver mode - This mode will display the screen saver animations.4. Infrared transmission mode - Under this mode, the user can select to send user contact information or

receive contact information by interrupt.

5. Contact Book mode This will allow the user to browse all stored contacts and view further details afterselection

Setup Instructions:

The system needs three voltage source, 5V, 3.1V and -5V.

1. Connect three grounds to a common one.2. Connect 5V to 8051 port 0 and VDD of external memory.3. Connect 3.1V to VDD of LCD.4. Connect -5V to VDD of op-amps between infrared transceiver and 8051.5. Set mode of emulator to 8X51(4K ROM), Internal Clock 24MHz.6. Simply runs the program and use buttons to select and confirm your actions.

Operating Instructions:

When LCD is displaying Main Menu, use buttons to move arrow up and down, and confirm your selection.

In display info mode, press enter to return to main menu.

In infrared mode, use buttons to move the arrow to select and confirm a contact to transmit.

In screen saver mode, if you want to return to main menu, simply press enter.

In contact book mode, after all names are loaded and shown on the LCD, move the arrow, with the help of

buttons, to select and confirm a particular contact in which you want to look in detail. After all information has been

shown, press enter to return to main menu.

If an interrupt is detected, which means someone is sending information through the infrared port to your device,

you just choose whether to accept or decline the users contact information by pushing buttons. The program will

automatically returns to the main menu after done with transmission.

Hardware Schematic:

Figure 2: Detailed Hardware Schematic

Hardware Description:

As shown in figure 1, the finalized device hardware design consists of 3 main aspects with the micro

controller centered as the control & data signal hub. The simplest hardware aspect is the direct pin to pin

connection from the 8051 to the RAMTRON FM1808-70-P. This connection is considerably net list intensive. We

could have used a D-Latch to alleviate this issue but since each component was used non-concurrently there was no

necessity to up free pins and we simply joined the high-byte FRAM address bus and LCD data bus as an alternative to

the addition of such a D Latch. In addition, since LCDs normally operate under relatively low voltage conditions wehad to make us of a step-down voltage buffer to interface the 8051 5V output pins to the 3V input pins of the LCD

module. Fortunately, we resolved this issue with the use of a BJT and a resistor since we deliberately did not make

use of the read - status function of the LCD such that the connection is one directional. Given that the load resistor

on the buffer is large enough this will also allow the BJT to reject the noise signals from the GND node as well as the

VDD node

Figure 3: Illustrated Schematic of the Hardware system layout Figure 4: Schematic of the voltage buffer


7/38

The more hardware involved aspect of this project was with respect to designing the IR transceiver. As

shown in FIG & FIG the IR transceiver consists of two individual OPAMP circuits that allow for half and full duplex IR

communication. Since this design uses a near IR (960nm) LED that is driven by a single stage inverting OPAMP. In

comparison the receiver module uses a near IR sensitive LDR that consists of a cascaded inverting and non-inverting

OPAMP. The two stage OPAMP circuit was necessary because the passive LDR has a very large resistance such that

and loading capacitance on the input amplifier has a very slow temporal response if the pull down resistor is not

made considerably small such that high switching speeds may be attained. Using a small pull down resister of course

degenerates the input signal from the LDR and thus requires the additional amplification stage. The pull down

resistor was a variable resistor so that we my later fine-tune the tradeoff between low signal degeneration or high

switching speed. Clearly inverting amplifiers were used so that the passive high state of the serial port is translated

to the passive low or no light state on the IR port which as results allows for better SNR. The OPAMP used was a

OP074 component which we connected to a +5 V and -5V voltage source but as result one also had to implement a

positive half wave rectifier circuit to protect the 8051 from negative voltage inputs. For convenience we simply used

the same voltage buffer circuit as the LCD set-up with its voltage source connected to 5V.

Software Description listed by function

Start up & Initialization:

The Startup sequence makes use of the LCD screen and the LETTER_TABLE which is described earlier. As the

program starts, initialization of stack pointer and variable definition will be executed. For demo use, we predefine

three users, including their names, email addresses, phone numbers and personalized icons, to store into the externa

memory so that we can show the contact book immediately after start sequence is done. The LCD_INIT function will

send a sequence of instructions, which refers to the data sheet, to LCD for initialization. A BLACK function will be

called to clear the screen and then program reaches Main_menu.

Main Menu:

Main Menu is more or less an idle state which listens to users input through buttons as well as waiting for

interrupt from the serial communication channel. The Start_Menu function displays four options, including Display

Info which shows basic information of products handler on LCD, Infrared which enters contact book, confirms

users will and sends out a particular contacts information through infrared port, Screen Saver which runs an

interesting animation and will be introduced later and Contact Book which make effective use of an fast and non-

volatile external memory as an folder to store other s contact details. An arrow is placed before the first option,

waiting for pushes over buttons. As long as enter button is pressed, the program reads the arrows position, does

an appropriate call. Meanwhile, if any interrupt from serial communication is detected, program will jump to the

interrupt vector to handle the information.

Figure 14: Flow Chart of Main Menu Program

Display Info:

This function is done by NMCARD function. This function is relatively simple since it makes use of

WRT_IN_ONE_PAGE function, which will be introduced later. Basically when entering the main menu, the program

will load a predefined user from ROM (USR_DEFINED1) to RAM (30H to 66H) then call WRT_IN_ONE_PAGE function

to display the information on the LCD.

Figure 15: Flow Chart of Show ID program

WRT_IN_ONE_PAGE: this function, which takes the row position, column position, start byte address, length of string

and a size indicator (bit F0) as input and output a set of instruction and data to the LCD so as to display character

onto screen, is the most frequently function that being called in the whole program. Due to the restriction of the LCD

module, we, at the very beginning, defined a table (

LETTER_TABLE) to draw every character and some special symbols (@. And etc.) The WRT_IN_ONE_PAGE function

first makes use of TRANSLATE_COLUMN_POINTER function to translate a column pointer into two instructions and

then send to the LCD. After setting the position, the function reads an ASCII code from the starting byte address andcalls MATCH_OFFSET to set the relative offset in the LETTER_TABLE.

Finally, WRT_IN_ONE_PAGE_ONE_LETTER function does some calculations to store the responding value in A and

send to the LCD module. This will display one single character at the desired position with a user-defined size (bit F0)

The function decrements string length and loop until a complete string is shown on the LCD.

Contact Book:

The contact book function was implemented for users to store and view other peoples information. This

function mainly makes use of 8051s parallel data bus and the high speed of a FRAM which was produced by

RAMTRON International.

Figure 16: Flow Chart of Contact Book Program

At the beginning of the CONTACT_BOOK function, the program will read the very first byte from the FRAM,

which indicates the number of current contacts in the contact book, then set a memory space 21H to loop through

the procedure to load all users names.

The function CONTACT_BOOK_DISPLAY will display a list of current users in the contact book. Basically itfollows the protocol for storing each user (i.e. first byte indicating length of name etc.), and display each users name

with the help of WRT_IN_ONE_PAGE function. Each time when it finishes displaying ones name, it will add the

pointer, which is the data pointer inside 8051, to the start of next contact.


13/38

Up to here, an arrow will point to the first person in the contact book. The user is allowed make a selection

by pushing the buttons. This procedure is simply implemented by polling technique which is the same as in the main

menu.

After confirming users selection, CONTACT_BOOK_PERSON function will display the persons information. It

first moves the FRAM pointer to the right position and then loads the 54 bytes into the RAM. Lastly it calls NMCARDfunction to display the particular persons information.

Screen Saver & the Graphical Animation

The screen saver mode that was implemented on this name card system makes use of the 8051s simple and

rapid computational power and the gray scale functionality of the graphical LCD. Although one can only display 4

shades of tone on the lm9300a LCD we were able to implement interesting visual effect by using a single two-

dimensional sine function. Due to our constraint on quick memory access we decided to let an algorithm generate a

picture frame on the fly instead of storing the frame in the external or internal memory allowing a much more

dynamic picture that it not constrained to its resolution as well as achieving much higher frame rates. The animation

(SEE A_INIT) consists of 32 unique frames in which the program loops though back and forth effectively looping a 64

frame moving picture. Each frame consists of 128 by 56 pixels that are calculated with dependence on the pixel (X &

Y) position as well as the current frame number. By simple scaling and manipulation of these three variables we can

formulate a function that manipulates the offset of a data pointer which points to 64byte stack that holds a sine

approximation. Using the resulting sine value we can determine which shade of gray the particular pixel is. Iterating

this algorithm across the LCD screen per frame created the following effect.

Figure 17: illustration of Animation Sequence

The complete program that handles this algorithm A_INIT consists of a initialization followed by 3 nested loops;

A_LOOP, A_LOOP1, and A_LOOP2. Intuitively each loop handles one of the before mentioned variables; Frame

number, page position, and column position respectively. These loops simple handle the current pixel variable states

in specified registers as wells as readjusting the LCD DRAM pointer once a loop is initialized. Within these loops there

exists a function called ARRAY_GEN. This function is necessary because LCD reads two bytes of information per

write instruction which corresponds to writing a whole column on a specific page in 4-level gray scale per write data

function. As a result one must pre calculate these two bytes before we call the function. We note here that this

function make use of the two bit addressable registers at location 20H & 21H to temporarily shift the relevant pixel

information in one by one.

As shown above we also implemented a roll over text (see WRITE_STRING) which makes effective use of the

function WRITE_TRACY and excellent use of the carry flag to detect a roll over letter case. The letter is printed one

by one with dependence on a column variable which depends on the frame number and a certain off set which of

course depends on the characters order which ranges from 1st up to 5th. It is advised however that the 5th character

a space or blank such that there is a separation between the end and beginning of the string. Intuitively, after the

completion of drawing a particular frame, the system checks the status of the return button allowing the user to

return to the main menu when pressing the return button.

Figure 18: Flow Chart of Animation Program

IR Communication and Transmission Protocol

We implemented the infrared communication protocol based on the situation of the hardware. The protocol include

2 parts, the transmission and the reception, respectively. These 2 parts follow some matched procedures, like the

echoing and the double send or receive for error check, etc.


15/38

Figure 19: Flow Chart of IR reception protocol

First we look at the sending, i.e. the method SND_IR, its jumped by an external interrupt of selecting the function

of infrared in the main menu and after choosing a right person to send. A confirms message will be asked to

confirm send, only yes will start the sending procedure and sending protocol. On start sending, the sender first

initializes a silence check to see if the infrared channel is idle, which enables REN and done by the loops of IR_LP1

and IR_LP2. If the SBUF is not empty, meaning theres other client sending information, then the program will jump

to a S_FAIL handler, implying a sending failure. Otherwise, the sender will send out an echo message with the

content AA (in the method ECO) when the channel is deemed idle. It then will wait for an echo back with the

same content of AA. If the sender doesnt receive the echo message back, it will keep sending echo. On receiving a

echo message, the sender will go to E_PAS and check if its the right echo message. If the message isnt AA, it wil

go to S_FL gain. Otherwise it will then send the contact information of the selected person twice. The contact

information is fixed as 54 bytes, with the three fields of 18 bytes, for name and phone number, logo, email,respectively. The reason we choose fixed length of data packages is first, its easy to handle, second, for variable size

of packages, both sides needs to check the size and the transmission procedure will not be fluent. Being not influent

in the transmission, the communications needs more checking and will introduce more noise, thus increases the erro

rate. As such, we chose to use the fixed data packages size. Finally after transmission, itll display the message as

DONE implying a successful transmission of the selected contact.

Figure 20: Flow Chart of IR Transmission Protocol

As mentioned above, the receiving procedure and protocol is similarly matched the sending part. Its implemented in

the method RCV_IR, included in the serial interrupt vector, showing that the serial reception is triggered by serial

interrupt of the RI flag, and this interrupt is only enabled in the main menu, which represents the idle state. On

receiving the serial interrupt and confirmed that its the RI, the receiver will clear the flag and jump to method

S_RCV, checking if the received package is the echo message AA first. If not, then the program will simply return

from this interrupt mode and back to idle state in the main menu, waiting for further instructions or interrupts.

Otherwise, itll disable the serial interrupt and start sending an echo AA back to the sender. Meanwhile, the

receiver will also start a timer for the timeout, in case it waits longer than 65.5ms and didnt get the echo back, itll

simply timeout and jump to an error handler (S_timer). But if the receiver gets the echo message back, then itll

prepare the start position and receive the first pack of the contact information (in RCV_USR), which includes 54

bytes as mentioned above. Itll store in the RAM while receiving, and start to receive the same pack of information

for the second time. In the second receiving, the receiver will first receive the package will check with the original

reception (CHK_USR method), if the second reception has any error with exceptions from the first reception, the

receiving program will jump to error handler S_ERR, which handles the error by re-enabling serial interrupt and

stopping the timer. Otherwise, the receiver will go on checking further errors, and if overall errorless, then itll jump

to INFRARED_INTO_FRAM, which stores the received contact information to the contact book stored in the

external RAM.

Conclusion and Evaluation:

The finalized Electronic Name Card design successfully met all our initial expectations and we were able to

implement an efficient and stable system. We found that even though our source code was not optimized to its full

extent the operation of the device was still very smooth and even the animation performed beyond our expectation

In addition we succeeded in wirelessly sending packages from one device to another with nearly 100% success rate.

For future improvements I would make an attempt to optimize the source code by unifying some of the

subprograms into a single general function that can be reused in multiple ways. This should increase programming

complexity but significantly reduce the code segment length. I would also like to include some sort of additional

notification when some ones contact information is received and the system prompt the user to save the data like a

buzzer sound for example. In addition I would like to allow the user to also disable the serial reception of other

peoples contact data with the use of some kind of switch so that one could ignore another person persistently trying

to send their contact info.

A more ambitions though would be to use a color screen instead of the gray scale LCD that is used in this

project to make the presentation even more appealing without necessarily increasing program complexity. This

would make the user interface much more capable to engage more complex functionality as well as make the

animation a much more interesting. As closing remark one may also like to standardize the contact information

package for future integration instead of using our developed protocol. An example would be the vCARD format that

is nowadays commonly used for the transmission of such data among mobile devices.
