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.

Operating the ADS1115 ADC in continuous mode with Arduino

ADS1115 is a 16-bit delta-sigma analogue to digital converter(ADC) designed by Texas Instruments. It has a maximum sampling rate of 860 samples per second. However, the maximum sampling rate can only be achieved in continuous mode. This article provides an Arduino example of how to interface the ADS1115 in continuous mode.
