nekuneko commented 4 years ago

Describe the scope of your change: Related to the pull-requests #124 and #118 I manage to make work my 160x80 mini BGR display module by performing these changes:
- Added two methods to manage hardware vscrolling on ST7735S driver.
- Changed init and inverted color behaviour to match the color scheme for 160x80 mini BGR.
- Changed _colstart and _rowstart values to match the 160x80 mini BGR bounds.
- Added madctl variable in order to simplify the code on setVerticalScrollConfig method.
- Added Arduino script to test all these changes all.
Describe any known limitations with your change. These changes are thanks to the code viewed on https://simple-circuit.com/st7735-tft-vertical-scrolling-ccs-c/ tutorial.
Please run any tests or examples that can exercise your modified code. I've tested the new testing sketch code on Adafruit Feather M0 and Adafruit Feather M4 succesfully. Please test it in your platforms and let me know if these changes works for you.

I hope this can get sorted out, I am using these displays and it would be nice to have them work without weirdness.
