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]
