Hey all,
I am doing a project on Vehicle Tracking System using GPS and GSM Modem.The 2 devices aforementioned communicates with 8051uC. But since there is only 1 UART in 8051 i have to use a analog multiplexer i.e CD 4062. I want to know how to interface it with GPS, GSM, and 8051.
Also it would be grateful if anyone could tell me how to parse output of GPS and how initialize a GPS receiver to that it starts giving me the GPRMC
Yes - you start by following the links you've already been given, and doing a bit of study and research.
"Ive been working with uC's for about a year or so but never did anything related to serial communication"
I find that quite amazing - to have gone a whole year and done nothing with serial comms!
Really, serial comms is a very, very, very common part of microcontroller/embedded systems!
After "blinky", a "hello, world" program on the UART must be one of most developer's first programs.
You really should have no problem at all finding plenty of examples of it!
