Problems with the Etherkit Si5351 Library

[frohro]

Hi Cadyn, I noted today that it looks like a person got the Etherkit library to work with the Si5351. They used GPIO20 and GPIO21, not the ones you used. You can change them with something like: Wire.setSDA(20); Wire.setSCL(21); The 20 and 21 are the GPIO numbers, not the pin numbers. You need to change the pin numbers to 4 and 5 respectively to match your PCB. He is using the Earl E. Philhower library to build the code. Rob

I played with it again, and I think the regular MBED library for the pico works now. We can close this.
