Is there any chance to make piscreen display working with BrickPi3? There is quite a lot pin overlaps: SPI pin19, 21, 23. Then some pins RPI_* 18, 22, 26. I guess there can be more than one device on SPI. What RPI_* pins are good for? Can there
We don’t support the piscreen display, and we can’t guarantee compatibility with BrickPi3. If you want to try to make it work, note that you shouldn’t use GP18 (HW pin 12 - BrickPi3 microcontroller reset) or GP7 (HW pin 26 - BrickPi3 SPI slave select).
GP9, GP10, and GP11 are the SPI lines MISO, MOSI, and SCK. As long as you don’t interfere with GP7 (SS), you can use these other three pins for SPI communication between BrickPi3 communication calls.
GP24 and GP25 can be used most of the time, as they are only used (in conjunction with GP18) for updating the BrickPi3 firmware.
