Hello. I am working on a senior design project and have a quick question.

What I am designing is a 2 digit 7-segment LED display that displays a value sent to it from a process running in Linux. I am thinking I will need to write a driver for the display to implement. How difficult will this be? I have Googled for about an hour and haven't found anything too helpful yet. There will be multiple USB devices plugged into the computer.

I'm not asking for help on creating the driver, just if a driver is necessary to send 1 byte of data to the display through USB.

Thanks.
