USB-TO-GPIO Adapter
The USB-TO-GPIO adapter is the link that allows the PC and the EVM to communicate. One end of
the USB-TO-GPIO adapter connects to the PC with the supplied USB cable. The other end of the
USB-TO-GPIO adapter connects to the EVM with the supplied ribbon cable.
When a command is written to the EVM, the interface program running on the PC sends the
commands to the PC USB port. The USB-TO-GPIO adapter receives the USB command, converts the
