I am new to Arduino and I have searched the Arduino forums for something that will help me do what I am trying to do. I have received value bits and parts of information. But I have been unable to piece these together to achieve my end goal.
I am trying to
(a) read in HEX bytes (like AA55FF66DDEE…etc upto 64bytes),
(b) I need to make sure that the keyboard entries are HEX values or Raise an error flag (“Incorrect Entry, not a hex number”)
(c) Display the enter Hex numbers (“You Entered: AA55FF66DDEE…”).
(d) Assign the Hex values that were read into something that I can use to write a CASE to do different things.
Thanks in advance.
