New to world of Arduino and as a electronic hardwear engineer this programing side is all new to me but learning fast thanks to the forums
Ok, i would like to use the function strtoul() but i don't fully understand how to use it so would like your help in understanding how to use the function correctly.
I have a ASCII string for example,
"41 05 1C 7B" (received over the serial)
but i'm only interested in the "1C 7B" and would like to convert it to HEX to get something like "0x1C7B" stored to a unsigned long. So if anyone could show/explain this to me it will be a great help.
Look forward to your replies, thanks.
