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...
STM32 I2C does not workSummary 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...
