I am new to programming in general, and I have hit a bit of a road block.
I am trying to communicate with an RFID module via a command protocol. Please see page 12 on the attached PDF. This is something which I don not fully understand, despite my endless attempts to get to understand it.
My question is: What way should I send the data to the reader? Should it be something like mySerial.println(“MOF”) and wait for response. Or should I write each character individually? This then brings up the question of what is, and how to write to serial?
I am kindof struggling with this topic at the moment, so if someone could offer any help or some relative literature which I could go through and maybe come back with more intelligible questions.
Many thanks, Micheal.
