HI Simon, I read your posts at Matrix multimedia. I wanted to know if you had successfully run both of gps and gsm modules on either PIC18F45K22 or PIC18F4455. I had used PIC18F2550 but it either runs gps (any baud rate) or gsm (any baudrate) but when I combine them together, then either of gps or g...

I am using the following chips: PIC18f2550 GSM Module SIM900D at 9600 baudrate GPS Module M-89 at 4800 baudrate Problem is that, I can not combine both functions at the same time in flowcode software. If I use GSM module in my flowcode then I lose functionality of GPS ie the GPS flowcode module neve...

I am currently designing a "Car Tracker System" . . . I am using PIC18F2525, a GPS and a GSM chip. . . The MCU should retrieve important from eeprom on reset, and connect to gprs. . . in the Infinite Loop, the MCU should repeat: look for GPS variables, look for port inputs, look for GSM instructions...
