How do ThreadX Message Queues work on STM32? Welcome back to the third part of the "How do ThreadX Message Queues work on STM32" article. 1. How to add Sender2 thread Now that the first demo is completed, let’s add our Sender2 thread and evaluate th...
This is the part 2 of the article to explain how the ThreadX Message Queue work on STM32 with working examples. Welcome back! 1. STM32CubeIDE – step by step demo: Launch STM32CubeIDE (version used 1.7.0), select your preferred workspace, click on Lau...
Message queues are the primary means of inter-thread communication in ThreadX. One or more messages can reside in a message queue. A message queue that holds a single message is commonly called a mailbox. Messages are copied to a queue by tx_queue_se...
A mutex is basically a binary semaphore, which means that only one thread can own a mutex at a time. In addition, the same thread may perform a successful mutex get operation on an owned mutex multiple times. There are two main operations on the mute...
Summary This FAQ describes few tips related to I2C peripheral on STM32 devices. 1. I2C Hardware 1.1 Signal integrity The I2C IO pins must be configured as open drain mode. The logic high level is driven by external pull-up resistor. Typical value of...
1. Introduction It is very common to have multiple GPIOs used as External Interrupt (EXTI) sources in an embedded system. But how to manage them in an application code? This is exactly what is going to be covered in this article. 2. Prerequisites Har...
1. Introduction The PSSI which stands for Parallel synchronous slave interface and was introduced in our high performance STM32H7 family. The PSSI can be used as a fast interface between two STM32 microcontrollers or between an STM32 and an MPU or FP...
Introduction When a specific STM32 part number selected for a project is not available in the desired time frame, it is essential to find a compatible alternative. This article guides you through the process of using STM32CubeMX to identify and confi...
Introduction A typical question new STM32 users ask is what are the preferred IDEs for developing and debugging application code. There are a variety of IDEs available that support the STM32. The most used are STs STM32CubeIDE, Visual Studio Code wit...
Baby Detector is an application developed to sense the presence of babies in a small environment. The idea is to face the problem of babies forgotten inside cars, that can lead to their death especially on hot summer days. The core elements of the sy...
1. Introduction and theory When running instance of FreeRTOS on each core, we can implement inter-process communication (IPC) using FreeRTOS message buffers as described here:https://www.freertos.org/2020/02/simple-multicore-core-to-core-communicatio...
In NanoEdge AI Studio v3, sensor data can be imported either from file, or "live" from a data logger via serial (USB) port. In both cases, the data format is the same. There are 3 cases to distinguish, depending on which project type is selected in ...
