I am using the RP2040 with the Earle Philhower Arduino library. I have tried all published Sparkfun examples GIT lab and website examples. I have added the SPI.setRx(pin_size_t pin), setTx, setSCK and setCS definitions so the library knows what pins to use related to how the carrier board is wired. I also have a Raspberry Pi pico and arduino library and have used read & write SPI communication with an MCP23S08. The only thing I have seen is using a non sparkfun library is the screen bkinks when using a rounded rectangle write function. It was not showing any thing but horizontal lines with 2 different levels of gray. GPIO numbers RX 20, TX 23, SCK 22 & CS 6. Has any one else had operation of this configuration? I tried using Arduino ide 1.8 and 2.0. If you were able to this working, please post any detail that would help. I have used MicroMod to work with AP color LEDs and Backlight brightness and read A0 as a digital in. If this should work, I may have just got a defective unit. Thanks in advance for help from tech support and/or forum users.
