I think I got this. I added a condition in ST7798_t3::init() as follows: } else if ((width == 320) && (height == 480)) { _colstart = 0; _colstart2 = 0; _rowstart = 0; _rowstart2 = 0; That seemed to set everything right...

This is the display: http://www.lcdwiki.com/3.5inch_IPS_SPI_Module_ST7796 There were a bunch of libraries and examples on that wiki page but they were very hardware specific and I couldn't get them to go with the Teensy (hackin' again)...

Looks like I will need to add some sizing support to void ST7789_t3::init(uint16_t width, uint16_t height, uint8_t mode) in ST7789_t3.cpp to account for a 3.5" display.

Welp, using the correct libraries worked perfectly, thanks again. FYI, I was using this Github: https://github.com/PaulStoffregen/ST7789_t3. I clearly didn't understand the ramifications. My next task is to get this going with a larger...

Really appreciate your help! That is not the GitHub I was using. I will review this, try again and get back.

I copied those two files where they could be found. So, I started over and downloaded the zip file and used the Include Library -> Add ZIP Library, same issue. I don't see that there is are st7735_t3.h/cpp files in that Github project. I tried to...

Tried that, same problem, but thanks.

I presume this is an easy answer because I didn't find anyone else with this problem. Just trying to compile the basic 'graphicstest.ino' in the PaulStoffregen/ST7789_t3 examples. This is with Arduino IDE. The compiler finds ST7789_t3 and...
