STM32, Arduino environment, ST7735 screen. Bugs and workarounds.
I was working with the ST7735 screen in a project at NTHUEE 822 Maker Space. We were controlling the screen with an STM32F103C8T6 Blue Pill and Adafruit's ST7735 & ST7789 library. And we ran into a very interesting bug, which was caused by the value of "pins" in the STM32 Arduino core. In this article, I will explain the cause of the bug and the workaround for current version of the libraries.
