An Open Source Library for Writing Firmware on the Cypress FX2 with SDCC

After playing around with the Cypress FX2 and SDCC for the past while, I’ve developed a library of utilities that make some of the common tasks for writing firmware and performing certain functions a little easier. I’m lucky to work for a company that approves of the open source initiative and believes that it is […]
