The Controller – G18 InterfaceThe Controller – G18 Interface
The F2812 DSP has two UART Serial Communication Interfaces (SCIA, SCIB), with which it will communicate with the g18 card, via two RS-232 ports.
RS-232 – CMOS level conversion between the two cards.
Communication with the g18 card will be at the HWI level.
Left to do:– Acquire RS-232 - 3.3V CMOS level converter.– Implement the communication drivers.

The Device DriversThe Device Drivers
RS-232 – UART Connection Levelsend(string), receive(string) interrupts through SCIA,SCIB
G18 Control Level- Implement control functions that send ATcommands: For Example: Network_Register(), Send_SMS(char *massage)- Interpret G18 feedback (SWI)
Application Interface Level-control functions
For Example: Init_communication(), Receive_Location()
