I've been using the Adafruit PiOLED which causes some issues with the PiSugar 2 battery I'm using. Because of this, I'm looking for recommendations on a screen that doesn't use the I2C protocol. I'd prefer one with no touch screen if possible.

  • Ah, there are in general two kinds of communication protocols for LCD/LED screens: I2C and SPI. For Rpi, there is a special interface for screens. You can google Rpi to find out more. – tlfong01 Jan 7 at 14:55
  • Gotcha, any recommendations for an SPI screen? I'm currently looking at this one: adafruit.com/product/4393 – Justanothermatt Jan 7 at 15:06
  • To add some context about the one I posted, I'm worried about using it because it is wired to use I2C but only for the STEMMA QT / Qwiic connector. If I omit that cable, I'm worried it will still cause issues – Justanothermatt Jan 7 at 15:10
  • I only know that Qwiic is SparkFun thing, but it is a physical non standard, so you can do your rewiring, similar to what I mess around RS232/serial standards with my own wiring hardware (yes, no nothing about DB9, double shielding etc, just cheapy 2.54 DuPont connectors), in my toy projects (115kBd, home environment). – tlfong01 Jan 8 at 2:45
  • I have posted a couple of answers in this forum on SPI/I2C LCD/LED displays. This is an example: raspberrypi.stackexchange.com/questions/98549/…. I vaguely remember my last post is about Piromoni SPI display which I think is good. I usually follow tutorials from AdaFruit and WaveShare, less frequently but more recently Piromoni and sparkFun. – tlfong01 Jan 8 at 2:50
