#Stm32 part number decoding driver

Instead of having to do the multiplexing work by our target microcontroller, the dot matrix module has a MAX7219 driver IC that will handle these multiplexing refresh cycles for us. One column can be controlled at a time, so we need to keep looping through all the columns quickly enough to trick the human eye to see what we want to show (which is called persistence of vision – POV). Just like the keypad matrix, the dot matrix display consists also of multiple rows and columns. Unlike small LCD screens that could only be used in close-range sort of applications, the dot matrix display is more fitted to showing messages or advertisements for a long distance. Mainly in any project where you need to have a display that could be seen from such a far distance. This is one of the most popular display modules that can be used in a wide range of projects.

In this tutorial: 4 LABs LAB 58 STM32 With 1 Independent Dot Matrix Display Unit (1 Module No Cascading) – Static Mode LAB 59 STM32 With 2 Independent Dot Matrix Display Units (1 Module Per Unit, No Cascading) – Static Mode LAB 60 STM32 With 1 Independent Dot Matrix Display Unit (2 Cascaded Modules) – Scrolling Mode LAB 61 STM32 With 1 Independent Dot Matrix Display Unit (2 Cascaded Modules) – Scrolling Mode + Manual Scroll Speed Control Without further ado, let’s get right into it! To get you started and help you understand the operation of each part in the systems we’ll be building. For testing our library, there will be 4 LABs in this tutorial. I’ll show you how my library works, the available APIs, and so on.

However, you can still use any other STM32 microcontroller part instead. I’ll be using the STM32F103C8T6 (blue pill) board, as usual.

Then, we’ll develop our own Dot Matrix Display Library (driver) based on HAL for STM32 microcontrollers as we’ve used to in this series of tutorials. Starting with how dot matrix display works and the features of the MAX7219 driver IC highlighted from the datasheet. In this tutorial, we’ll be interfacing STM32 with the MAX7219 Dot Matrix Display.
