This is a testing repo for the ST7789 135x240 screen to validate that a PR fixes an off-by-one issue. (News flash: My initial PR doesn't fix it fully!)
To try it out yourself, copy the contents of
test.cpp
into a new Arduino sketch, configure the TFT_CS, TFT_DC, and TFT_RST (and
optionally the BACKLIGHT) pin numbers and run it.
Correct operation should be a full bright green outline for all 4 orientations, and never a blue line anywhere (You may see the screen go fully blue occasionally, but it should immediately go back to black)
This repo is an overly-complicated setup so I could easily test my own fork of the fabulous Adafruit-ST7735-Library. (Seriously: buy their products, just to support their software. It's really, really good stuff).
For other reasons, I made a
tool a while back that spits out
Makefile includable stuff, so I can do make -j and compile & link an order of
magnitude or two faster than the silly Arduino Studio build system. (I'm quite
comfortable make sure I #include all the necessary files, Arduino, thanks
anyway). It's obviously faster on my Mac laptop & Mini. On my 12 core Windows
desktop? Yeah, there's just no contest. Besides the incredibly slow "let's check
to see if they forgot any #include files" step, the Arduino build is
single-threaded.
