Summary This article describes the steps that are needed to make time measurements of code execution using the GPIO pins 'EVENT OUT' function and a lab oscilloscope. Most of the STM32s GPIOs can be placed in an alternate function of EVENTOUT. In th...
1. Introduction The STM32’s integrated LTDC (LCD-TFT Display Controller) peripheral can be used to interface with parallel displays. It is very common for HMI-of-Things applications to have the capability to control and display data between user and ...
1. Introduction In most of the STM32’s ADC (Analog Digital Converter), there is a feature called the Analog Watchdog. In this article we will learn how to configure it using the STM32CubeIDE tool and how to use it in an application. 2. Prerequisites...
ThreadX provides 32-bit counting semaphores that range in value between 0 and 4,294,967,295. There are two operations for counting semaphores: tx_semaphore_get and tx_semaphore_put. The get operation decreases the semaphore by one. If the semaphore i...
In continuation of part 1 of this article [1], we will also briefly discuss how you can easily export your STM32 project to different STM32 series using the “List pinout compatible MCUs” option in the STM32CubeMX. 1 Troubleshooting sourcing the STM32...
The following article is part 1/2. In part 2, we briefly discuss how you can easily export your STM32 project to different STM32 series using the “List Pinout Compatible MCUs” option in the STM32CubeMX. Furthermore, part 2 also includes troubleshooti...
You can reach 480MHz only for the following STM32H7 part numbers: STM32H747/757 STM32H745/755 STM32H743/753STM32H742STM32H750 Note: For some parts, you need to check the maximum frequency from the datasheet.This is not enough! you also need to check...
Question How to add or update the SVD file in a project using STM32CubeIDE, IAR or Keil®? Answer 1. Introduction To check the behavior of the project, it is necessary to control the changes made to registers status. To do that, it is important to ...
Introduction Welcome! In this article, we will cover how to run a Bluetooth® Low Energy application simultaneously with USB CDC functionality on STM32WB55xx devices.When trying to run both APIs together, we need to pay attention to some details regar...
1. Introduction Onboard, the NUCLEO-WB55RG includes a ST-LINK/V2-1 debugger/programmer with USB reenumeration capability: mass storage, virtual COM port and debug port.The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 mic...
Introduction In this article we will see how to create an I2C target device with interrupts using the STM32CubeMX and STM32Cube HAL Library. All the I2C target communication will be handled by firmware. 1. Pre-requisites1.1 Hardware: Micro USB cable...
Welcome to the second part of the article covering how to use the Mutex in the ThreadX using STM32 (Part 1 available here). This will cover the code editing and debugging. 1. Code Editing and debugging Using the previously code generated, open Core\S...
