sending data to usart of a pic18f452

[abdulmajid]

I need assembly code which samples an analog signal (0-5V) every 5 seconds, convert it via the internal ADC of the pic18f452 and then send this data to the usart to be transmitted to a pc via two gprs modems, on connected to the usart of the pic and one connected to the pc. any ideas? I will be using modbus software (on pc end) to poll the gprs modem connected to the pic.

I look for assembly program pic18F452 that written DTMF "dual tone multi frequencies" any one can help please send me email [email protected]

PBP has no problem with DTMF tone generation. The limitation is that the PIC can do virtually nothing else while generating these tones. It can, however, receive up to two bytes of data over the hardware USART while doing other things.
