 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

just happened upon the following: https://www.eevblog.com/forum/projects/usb-sniffer-using-rp2040/ it uses just a PICO and a USB extension cable to monitor Full Speed and Low Speed traffic. looks like it could be useful in diagnosing issues with USB devices. there is also a link to a nice RP2040 PCB that brings out all 30 GPIO lines: https://github.com/ataradov/breakout-boards/tree/master/rp2040 cheers, rob :-) |

Yes, that looks like it could be useful if you are working with USB coding. I'm far to scared of USB technically speaking, so I leave that to others who know what they are doing, and stick to my old-school UART.  Smoke makes things work. When the smoke gets out, it stops! |
