Lots of things are working now!
* digitalWrite/Read
* shiftIn/Out (tested using Nokia5110 https://github.com/ionpan/Nokia5110.git)
* SPI/Wire (tested using SdFat 2.0 https://github.com/greiman/SdFat.git ... note that the Pico voltage regulator can't reliably supply enough power for a SD Card so use external power)
* digitalWrite/Read (basic sanity tested)
* shiftIn/Out (tested using Nokia5110 https://github.com/ionpan/Nokia5110)
* SPI (tested using SdFat 2.0 https://github.com/greiman/SdFat ... note that the Pico voltage regulator can't reliably supply enough power for a SD Card so use external power)
* analogWrite/PWM (tested using Fade.ino)
* Wire/I2C (tested using DS3231 https://github.com/rodan/ds3231)
