25. How to Interface an LCD to an ARM Microcontroller Tutorial – Part 12

Purchase my new book: Arm Microcontroller Programming and Circuit Building Volume 1

I recommend using the STM32CubeIDE:

You can still download the CoIDE here:

In this video, a look at the timing of the LCD is done so we can make sure the LCD is ready for characters to be delivered by the STM32 microcontroller. How to interface an LCD requires that you respect the time the LCD takes to do it’s work internally. The ARM Microcontroller is much faster than the LCD display.

In this video, I am programming for a 16×2 LCD, but an LCD with more lines and characters per line is ok.

The way I teach is to understand the fundamentals of production, not Arduino style one-off projects. I urge all Arduino fans that want to develop projects that will be offered to consumers to be production oriented and use the Arduino bare chip to learn how to develop rather than using the Sketch environment and the Arduino boards that contain many passive components that need to be removed during the production development phases.
