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...
