I could not able to transmit the data through the UART when i run the program. But when i put a breakpoint, it seems working fine. May i know where is the problem? i seems like i could not find it. thanks
today i did proble the transmit port from the uC and i could able to see the command send through oscillscope. At first, my guess was the transmit part got problem but i seems like not. I m totally lost about this because i not really sure where my problems lies at.
If you're lost when you have all the code and the hardware and all the information in front of you, how do you expect anyone else to know what's going on when we can't even see all of your code?!
Where did the code come from? Presumably, you didn't write it yourself? Can you contact the original author?
You seem to have basic problems with the operation of your buffered UART "driver". You really need to isolate that part and concentrate on understanding it and getting it working. The GPS unit and everything else are just unnessary distractions & complications at this point.
