This kind of display, tipically selled on the internet with ST7735S driver, looks like to be BGR, use different bounds coordinates, and the color scheme is inverted by default. Hardware vscroll is available on ST7735S driver, see datasheet for more information. These changes are thanks to the code viewed on https://simple-circuit.com/st7735-tft-vertical-scrolling-ccs-c/ tutorial.
Also includes ST7735S 160x80 mini BGR color scheme test.
Changes to match esp8266 needs

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

Please, feel free to test the changes, if any issue please post it and we will discuss it. :D |
Will do. So far, so good 👍 |

Describe the scope of your change: Related to the pull-requests Add init method for ST7735S (RGB, 80x160) #124 and add support for another 160x80 module #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
_colstartand_rowstartvalues to match the 160x80 mini BGR bounds.- Added
madctlvariable in order to simplify the code onsetVerticalScrollConfigmethod.- 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.
