i would like my Pro mini to do the following every 1sec:
- transmit the following TTL message:
- receive the following TTL message (from an external source that replies to #1):
1,RAC,1 // Echo of the received command
Then, for each parameter seperated with a comma, i would like to save in EEPROM (i know how to save to EEPROM).
- print the saved parmeters from EEPROM to LCD (i know the lcd.print function).
my main issue is how do i “listen” for the incoming string and then saved each parameter to EEPROM.
actually, since the parameters refresh every second, i dont even need to save them, i could just print them to the LCF right away.
Can anyone point me to some good info on how to “listen” for a certain string on the TTL input, and once it arrives, save it for LCD printing?
