STM32 microcontrollers.
Today I would like to talk with you about the L3GD20 digital gyroscope. We will discuss the main features of this sensor and create an example project for STM32 microcontroller. L3GD20 – is a small chip, produced by the STMicroelectronics. It can measure the three-axis angular rate and provide it through a digital interface – ...
Hi to all! In one of previous posts I promised to tell about the clock configuration in the STM32CubeMx. So this article is devoted to the RCC and the clock frequencies. We’ll also consider some examples today, so we’ll take the project from the post about the timer configuration as a basis. Let’s open this ...
We continue to improve our STM32CubeMx course and today we’ll speak about the combined usage of SPI and DMA peripherals. Of course, we’ll also create an example for STM32 microcontrollers. To make our task more difficult I’ve decided to use four SPI modules and respectively four different DMA channels. So, let’s begin immediately! 🙂 Firstly, ...
My aim for today’s post is to show an example of Virtual COM Port USB mode. Some time ago we worked with the USB Mass Storage mode - please don't miss this article 🙂 In previous posts devoted to the STM32CubeMx I've used the STM32F4Discovery board, so today I'll use it again 🙂 It's very ...
Hi to all visitors of our site! Today I'd like to talk about the STM32 ADC peripheral module and it's configuration via STM32CubeMx. Before speaking about the aspects of configuration the project, I'd like to say some words about the challenge of this article 🙂 Let's toggle leds on the development board (STM32F4Discovery) depending on ...
Hello to all! Today we'll try to connect SD-card to our STM32 microcontroller and to create a FAT filesystem on it. In order to test the filesystem we'll create a new file and write some data to it. In previous posts I've used the STM32F4Discovery board, but today the development board with the STM32F10x MCU ...
Let's continue with STM32CubeMx application and different MCU units. Today we'll configure and use the STM32 USART interface! We'll set ourselves the following task: Thus, in case of receiving the correct amount of data we can see that the USART module is configured correctly. I'll use the STM32F4Discovery development board so the project should be ...
Within series of articles devoted to STM32CubeMx we start discussing different USB modes. And today we'll realize USB Mass Storage Device class with SD-Card connected to the MCU. Thus, microcontroller STM32F10x acting as a card reader will be the result of this post 🙂 As I've mentioned at the beggining of the post, I'll use ...
Some time ago I developed my own USART library for STM32, and it turned out to be very effective. So, I've decided to share it with you. I hope you'll also find it very useful 🙂 In this article I'll describe the USART library and some of its features and give an example of using ...
Hi to everyone! Today we'll continue studying STM32CubeMx! The next stage is configuring STM32 timer parameters and using interrupts. Here are the previous posts: Previous post has been devoted to GPIO configuration, we learned how to turn on/off LEDs with the help of STM32CubeMx. So, today we will also toggle the LED, but we'll do ...
