WebDec 7, 2024 · STM32 I2C peripheral is simple enough to use without the burden of HAL libraries, additionally I needed a custom driver because my application uses FreeRTOS. This driver supports both sending and receiving data from most common I2C slaves. Very often an I2C slave has its own registers that can be read and written. WebThe taskENTER_CRITICAL () and taskEXIT_CRITICAL () macros provide a basic critical section implementation that works by simply disabling interrupts, either globally, or up to a specific interrupt priority level.

WebOct 20, 2024 · The reason for calling vTaskDelay () is to give other tasks a chance to run while this task is delaying. So it seems counterproductive to disable interrupts with taskENTER_CRITICAL. If you don't want other tasks to run during the delays then call a non-blocking delay function rather than vTaskDelay ().

WebSep 26, 2024 · Entering a critical section means that interrupts ( up to a certain priority ) are suppressed. Now you call xSemaphoreTake() during a critical section: how can it block when interrupts are not allowed. PS. Have you defined configASSERT() in a proper way ? I would recommend to either use a semaphore, or a critical section, preferably the former.
