Hello,
I'm using the USB Host shield from sparkfun:
And the Arduino Mega, I already solder the pins and it's already stacked up with the board.
I'm trying to figure out how to read and write hex data from a connected device.
by example, I want to send the hex code A9A2 and it will reply with B9B1.
I already installed the library
and run the acm_terminal example by I'm stucked in there.
Any help will be appreciated.
