We've been using ESPs more and more recently at MAGFest, we were up to 3,000 this year. We are considering a possible direction which would enable us to use many, many more, but we would need to do the two things described at the bottom of this message. Additional PHY register documentation or an ex...

【Resolved】Need better interrupt access for Full-Speed USB

Just to point it out - I do have my ESP8266/ESP8285 communicating at low-speed USB, and I can do things like make it enumerate as a mouse and flash it over the USB interface... https://github.com/cnlohr/espusb Though I am still not 100% sure I can get full-speed USB working, but I think I can so lon...
