I connected a STM32F411 to a 16 X 2 LCD using I2C to respond to a comment I received in my Youtube Channel. I decided it might be of some use to someone else so I created this video. As part of this exercise I also connected the STM32 to a 20 X 4 LCD using I2C. The video shows a demo, loading the required library, Arduino IDE loading set up and the sketch example modified for the different LCD displays.
