Manage embedded software libraries with STM32CubeMX

Starting with STM32CubeMX version 4.27.0 ST added an option to manage embedded software libraries directly into CubeMX and have fully integrated graphical tool to configure project into very details before building application in final toolchain (Keil, IAR, TrueSTUDIO, …). Embedded software libraries are libraries (also) provided by STMicroelectronics. You will notice them with X-CUBE-library_name name format, like X-CUBE-MEMS1 which is complete solution for ST MEMS sensors. Steps to follow To enable embedded libraries to be added to CubeMX, please follow steps, explained...

Getting started with STM32 step-by-step

STMicroelectronics recently launched STM32 step-by-step learning program to educate and speed-up learning curve. It is ready for beginners and everyone interested to learn STM32 ARM-Cortex-M based microcontrollers together with its ecosystem around microcontroller itself. From beginner to pro in 5 steps Step 1: Pre-requisites: In this part, user must install all required software tools and make sure it has board for further development Step 2: LED blinking using STM32CubeMx and NUCLEO-L476RG development board Step 3: UART interface on NUCLEO-L476RG and L475 IoT...

C code style and coding rules

I’ve been trying to make my own C code style and coding rules approach, to be used in all my libs. From my first coding experience till today, I changed style many times, from first STM32F4 Library to latest projects, such as ESP_AT_Lib, onewire_uart and others.   Code style rules are published and regularly updated on my Github account, under c_code_style repository name. Please use URL below to access website: https://github.com/MaJerle/c_code_style It was originally inspired by LwIP coding style with some modification....

Tutorial: Control WS2812B leds with STM32

In this tutorial I will explain how to drive WS2812B with STM32 using TIM PWM and DMA peripherals in the most efficient way by using minimum amount of RAM, required to process all leds. There is a good explanation, already available on the web. If you have no experience with WS2812B leds, I strongly recommend you to read the blog post. It is very well written, but it has one major issue. It uses 24 words of RAM for each LED,...

STM32 tutorial: Efficiently receive UART data using DMA

Latest updates and examples are available at my official Github repository. STM32 + UART + DMA RX + unknown length This repository may give you information about how to read data on UART by using DMA when number of bytes to receive is not known in advance. In STM32 microcontroller family, U(S)ART reception can work in different modes: Polling mode (no DMA, no IRQ): Application must poll for status bits to check if new character has been received and read...

EasyGUI preview on STM32F7-Discovery

Last 2 months I was working hard to build a platform independent graphical user interface library for embedded systems. I called it EasyGUI because idea behind is very simple library with support for custom user based widgets with touch and keyboard support. So far I built these features: Unlimited widgets (limited to RAM memory) Support for widgets which support children widgets (windows, panels, etc) Support for touch and keyboard events Support for UTF-8 encode and decode functions Support for custom...
