Assume that the following message frame has come from the remote sender:Ġ21356753503 //STX Data1 Data2 Data3 CKSUM ETXģ. The C program isn’t even my problem at the moment. Is the data item of the frame is ASCII Coded binary? If so, provide an example.Ģ. Hello, I’ve been following this tutorial to interface between a C program and my Arduino. RxData = Serial.read() Serial.print(rxData) ġ. HEX : 02 Data Data Data CheckSum 03, but Variable Length.įixed Value : value = 0x02, value = 0x03 In the original 1963 definition of the ASCII standard the name start of message was used, which has been renamed to start of heading in the final release.
