Could you add a wireup diagram between the Pico and the TFT? |

Sure, thanks... I've tried various but the current one using shown in the code above is: As I've continued to work on this I was able to get https://github.com/Bodmer/TFT_eSPI to fully work with the Pico and this screen. So that's very positive! This could be the solution for me for now... but as I've gone thru this much - maybe I can help see if we can get this to work with Pico and this common screen and help spell out the config needed to get it to work more directly with arduino-pico. In TFT_eSPI there definitely was a big step to configure with the User_Setups folder and file...so maybe that is the missing step here that isn't well documented??? idk. |

I appreciate the guidance from other related forum posts but can't seem to get anything to work for my SPI Screen. A different screen but similar and common type. GMT130-V1.0 From GoldenMorning (looks the same as many off of Amazon etc.) using ST7789
Could you please show the code you used to get it working (and pin out)? I've tried every combo I can think of but can't get it to display anything.
Also, of important note: The screen does work! and with Arduino. I had a Teensy 3.6 lying around and tried it and it works fine; displaying the whole demo perfectly. So just wanted to clear that up that I know the screen works, just not with the pico and arduino-pico. :(
This is the code that works on the Teensy (tried it and many variations on pico) (commented out stuff attest to what was tried)
(it continues but it just mirrors the basic example from adafruit)
Code of what exactly works here (especially regarding any SPI configuration needed here but not in teensy) would be very appreciated and the pinout that is required. I also tried various SPI or SPI1 (&SPI1) combos to no avail - but could use guidance on what really works for that - I could use SPI0 or SPI1...it doesn't matter here - anything that would work.
Thank you, please help!
