Hi to all,
Happy New Year...
When i interface a GPS receiver with 89c51 microcontroller... i can able to receive data using UART but when i display it in LCD it shows random characters... often shows D with few other characters like j,s,p,t,u,w....
What mights be the problem...
I have written the coding in MikroC compiler for 8051...
Baud rate :4800 bps
Not all GPS start from the NMEA-183 specified 4800 baud rate.
A serial GPS with RS232 output is the wrong levels for inputting to a microcontroller, and it's also the inverted. You need a level shifter like a MAX232 to make those compatible with a uC. But, bare GPS modules usually DO output 5v/0v levels, without inversion, instead of RS232.

hey i require information regarding gps interfacing with mew p..
can u please suggest me which gps should i use along with the mew p specifications also which would make things easier...my objective is to obtain the lat/long from the gps and then send it using RF transmitter...
You have to check two things the first is baud rate of the GPS receiver must be the same as the UART of the microcontroller and the second thing is to check the data coming from the GPS may be it is inverted so use inverters to invert the data before you read it by the microcontroller
Why are the urgent requests always requests for total project design advice? I can't remember ever seeing an 'urgent request' that had a specific answer; They are always things like "I need to make a touchscreen smartphone. Please suggest any hardware that is required and describe its function. Thanks you."
