Wrong pin number in ilidriver.c #1

Closed kagouraki closed 1 year ago

kagouraki commented 1 year ago

I am trying to connect a TFT SPI 3.2 inch display with ILI9341 to an esp32 LOLIN32. I have a TTGO T-Display 1.14 Inch LCD and works perfect with the micropython file you provided in this thread

https://forum.openmarine.net/showthread.php?tid=3849&page=4 plus the "make upload" from HAT directory

When i replicate the steps for the Lolin32 with the 3.2 display i get nothing on the screen. I connected the pins of the screen as the product description of the TTGO diplay says.

Notice the RST pin. It says pin 23 but in your ilidriver.c file the RST pin is 20. There is no gpio20 on the esp32.

If you change the pin number in the code does it work?

Different boards use different pins.

Yes i changed the RST from 20 to 23, compiled micropython with ugfx again and the screen works. Tomorrow i will modify the driver because the screen has inverted collors, is mirrored, i want portrait and the size is small. 

I forked and made another branch. If i manage to do this i will push a commit and remember this time not to change you defaults like the touchbutton addition i made so you can merge is directly. 

My setup will be a stationary pypilot remote powered by ships service battery and touchpads instead of buttons(easier waterproofing). Of course i will share pcb,case parts and a guide when i am done.

You made an awesome work. I hope you had more comments though. I am a hobbist and my regular job has nothing to do with pc programing. 😅 Takes time to understand but baby steps !
