This section will cover how to access your board's pins using CircuitPython, I bought a Graphic LCD 12864 Driver ST7920 for a while but I can't find a library to work with it. However the code does not compile for the RP2040 and throws a . For the read methods I use Raspberry Pi Pico. Why does the RP2040 have an SPI CSn pin? That’s only for when the RP2040 acts as the SPI slave, right? When it’s the SPI master, it has to use several independent GPIO pins as chip-select pins, one per 1- I actually am using SPI on my Raspberry so I have dtparam=spi=on 2- I am using BCM-GPIO-21 (PIN 40 on my Raspberry 3 Model B+) as an input pin for other purposes. Some CircuitPython boards do have default SPI pins, but the Pico isn't one of them, so any time you initialise a SPI object, you need to define all 3 pins. cocoa Posts: 5 Joined: Wed Jun 05, 2024 8:04 am.
