Using JX-877 boardPreparation

Before using, user must prepare some tool and software following :

1. Personal computer which install Window 95/98/ME/2000/XP, text editorprogram, MPLAB, MPASM and Miracle-PIC software

MPLAB and MPASM are licenced by Microchip Technology , for moreinformation please contact at http://www.microchip.com (included in CD-ROMwhen order JX-877 board)

Miracle-PIC is licenced by Innovative Experiment Co.Ltd. Pleasecontact at www.inex.co.th (included in CD-ROM when order JX-877 board)

2. Write program, set beginning address at 0x0000 and save file in .ASM

3. Assembler .ASM file by MPASM with selected INHX8M type. So it will beHEX file

4. Prepare DC adpator 16-20V 500mA.

Procedure1. Constuct the curcuit, solder the components on prototype area on JX-8772. Connect JX-877 with PC’s parallel port.3. Supply voltage to JX-877 board, green LED at “RUN” mode is bright.4. Press MODE switch for changing to PROGRAM mode, red LED is bright.5. Open mPicFlash.EXE (after install Miracle PIC flash software)6. Select PIC16F877 or PIC16F877A microcontroller.7. Open HEX file.

8. Erase data in microcontroller by pressed

9. Check blank data in microcontroller by pressed

10. Program data in microcontroller by pressed

11. Check the result by pressed and notice12. In case, protect data.Select code protection in View Configuration.

PIC16F877 can choose 4 protection types; CP All, 1000H-1FFH, 1F00H-1FFH and CPOFF. These protection types have to choose before prigramming. Moreover, userscan protect data from EEPROM by select CPD in Configuration.

13. After programming completed, press MODE switch to RUN mode.Microcontroller will runs your own program.

14. Save in desk, have to code protect. User can check by put microcontrollerin socket, open Miracle-PIC program after that, press READ then select View menu

Program buffer and Data buffer.If showing 000, means code protect. After readdata, select File menu Save file As and name file.HEX

Main Control ButtomOpen mPicLite.EXE program, then select the microcontroller as figure 1, there

is 8 function buttons follow this;

Open : Open HEX file

Save : Save source code in HEX file

PROGRAM : Program all data into program memory and EEPROM

VERIFY : Test program; compare data in buffer with MCU’s data

READ : Read data from selected microcontroller and also readparameter

BLANK CHECK : Check blank data inside microcontroller

ERASE : Delete data in program memory of selectedmicrocontroller. This function used with flashmicrocontroller memory or EEPROM only.For example, PIC16C84 or PIC 16Fxxx

Select microcontroller : Just click at the arrow. User will see many MCU lising.

Configuration SettingBefore programing PIC microcontroller, always fix configuraruon, go to View

� Configuration. This is detail of them.

Oscillator - select clock mode, there are 4 types (for PIC16F877-20/P)LP - low cystal (not use in JX-877)XT - normal cystal not over 4 MHz (not use in JX-877)HS - Over 4 MHz high frequency xtalRC - External RC circuit (not use in JX-877)

Code protection - Use for selceting protection mode. It can protect data inPIC16F877 microcontroller is 4 modes include : ALL, 1F00H-1FFFH, 1000H-1FFFH andOFF. Select CPD box for protection data in EEPROM.

Configuration - To select special ability of PIC miocrocontroller, it dependson type of microcontroller. For PIC16F877 has 6 types;

WPT (watchdog Timer)PWRT (Power-up Timer)BODEN (Brown-out Reset)LVP (Low Voltage program) - Enable programming to PIC

microcontroller with low voltage+5V instead of +12V (Should not use with JX-877)

Figure 3 : Data buffer window, user can see all data in EEPROM within microcontrollerand edit any address

6 JX-877 40-pin PIC microcontroller project board

ICD (In-circuit Debugger) - Edit program memory in positionOX0100(100H) up via RB6 and RB7 so RB6 and RB7 is not work(no use in JX-877)

WRT (Flash progran write) - If select this function, users canprogram data into flash program memory via resistor EECON. On the other hand,no select this, the program in the memory have to do via RB6 and RB7 in normally.

DeviceSelect type of PIC microcontroller

CommandArrange reading, writing and testing data in microcontroller memory

Program Chip (F4) - Program code and data to microcontroller asPROGRAM buttom

Verify Chip (F5) - Check writing data in PIC microcontroller corrector incorrect as VERIFY buttom

Read Chip (F6) - Read data from microcontroller as READ buttom

Erase Chip (F7) - Delete data in PIC microconrtoller as ERASE buttom

Blank Chip (F8) - Check blank data in PIC microcontroller memoryas BLANK CHECK button

OptionSeparate 4 parts;

Part1Program/Verify Program - check latest programming in microcontroller

with buffer.Program/Verify Data - check data in microcontroller memory after
