 08 Oct 2009 14:27 Help Needed: GPS and GSM Communication project with PIC |
|
|

|
Hi All,
I am going to start work on a Tracker project that will use GPS to locate the car and send the location via GSM.
I will need two Serial ports PIC for this project. Can anyone please guide me for the right selection of PIC? Also, i am trying to get a low cost solution, so any suggestions for simulating serial port without UART??
Plz your comments will be appreciated.
Regards,

If you need a PIC with 2 x hardware UART AND EEPROM, youre looking for the 16 bits series.
There are a couple 18F 8-bits but they dont have EEPROM.
You could build logic to multiplex the signal and only use one UART.
I would definitely use a hardware UART so dont try to go too cheap.

Dear you should use 74151 or 4052 or 4067 Multiplexer to multiplex the signals of GPS and GSM. And use just single UART.
