Hi
I'm building a program which send a command to microcontroller, for instance: send number '1' --> channel ADC 1 OFF. And there is my problem: I have 4 channels, which measure ADC voltage on input. I really don't like soldering (:D) so I'd like to turn praticular channel on/off in my program by sending a command to microcontroller. 4 channels, 2 different status -> 16 different combinations. Have you any idea how simplify this process? Maybe I should send a xxxx numeric (x - refers to state 1 OFF, 2 ON, example '1378', channel 1 ON, channel 2 ON, channel 3 ON, channel 9 OFF), and load it to frame in microcontroler? Byte UDR, which is in charge of reception, have 8 bits, so I have to send '1378' one number by one and I can't do it. Any ideas? :)
