I sent an email to the fx2lib mailing list that I thought would make good information for a bigger audience. Eventually, I’ll probably provide a Verilog behavioral model for the GPIF on the Cy7C68013 (and variants), but for now, this may help a few of you: Rdy0,1, txpire etc, are registered (The data 7:0 is […]

I’m lucky to work for a company that approves of the open source initiative and believes that it is […]
I’ve had the enjoyable experience of playing around with the Cy7c68013a chip on the Ez-Usb development board for the past few weeks. I thought I’d post a few tips for developing in this type of environment with open source software. Convert to Linux The tools that Cypress provides with the development kit are Windows based. […]
