STM32 Tutorial

The STM32F4 microcontroller series is popular in embedded systems applications due to its powerful features. One of its key peripherals is the Digital-to-Analog Converter (DAC), which enables the generation of analog waveforms. In this article, I will show you how to generate sine, triangular, and sawtooth waveforms using the STM32F4 …

The serial port is the most usual comm channel between a microcontroller and a computer. However, the different voltage levels and loss of the RS-232 port in modern computers led to the use of USB-TLL converter chips like CH340, CP2102, etc. This is what happens in the NodeMCU ESP8266 and …

Needless to say, a serial output is a necessary tool in debugging embedded system applications. Placing the right messages in the right place will help you save hours in figuring out what went wrong in your code. Arduino programmers are very familiar with Serial. print() and its derivatives. But how can …

I just got my hands on a STM32F407VET black development board from China and was excited about the possible projects I can build with it. To my demise, there’s not much information about programming the board so I had to find that out by myself. This post is for those …

If you’re looking to learn how to make your own electronic devices at home, it’s important to understand that you’re going to need two things: a microprocessor and the microprocessor board to put it on. In an earlier post, we taught you how to program the PIC16F84A — sometimes known as …

Arduino is easy to use but that’s at the expense of numerous features, the most glaring of them is speed. Hence you would rarely see an Arduino in an embedded, industrial setting. ARM Cortex-M microcontrollers are low-cost, energy-efficient 32-bit devices with up to 2 DMIPS/MHz. They are the microcontroller of …

Debugging through the serial port is one of the ways to find errors in your code. In this tutorial, I’ll show you how to add serial communication function to your STM32 Nucleo board.

We managed to blink an LED in the previous tutorial. This time, still featuring the STM32F1 Nucleo, we will add a button that will control the attached LED and a simple clap switch.

On the previous tutorial, we managed to create our first program with the STM32 Nucleo board. Now we will dig deeper on the pinout and other functionalities of the board.

The STM32 Nucleo boards by ST pack a lot more power than an Arduino UNO and have headers aligned the same way with the latter which makes it compatible with Arduino shields.
