Webissues contain lock and unlock hooks. The lock hook is called at entry of the critical section, and the unlock hook is called at the exit of the critical section. The thread-safe solution implements the required lock-related functions. Figure 2 indicates a simplified interaction between the user code, the C library and the thread-safe solution upon WebMar 3, 2015 · To solve this trouble, I added taskENTER CRITICAL (); and taskEXIT CRITICAL (); between the beggining and the end of the I2C communication function, to be sure that this region will not be swapped by the RTOS scheduler. To my surprise it did not affect the task swapping, vScreen_Loop is still swapped by vCore_Loop during the I2C communication.

WebOct 13, 2024 · This means that he, at least, is 100% sure 4-byte reads and writes are atomic on STM32. He doesn't mention smaller-byte reads, but for 4-byte reads he is conclusively sure. I have to assume that 4-byte variables being the native processor width, and also, word-aligned, is critical to this being true. WebtaskEXIT_CRITICAL_ISR(&spinlock) exits a critical section from an interrupt context. Note. The critical section API can be called recursively (i.e., nested critical sections). Entering a critical section multiple times recursively is valid so long as the critical section is exited the same number of times it was entered. career share nm

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.

WebApr 13, 2024 · This is exactly what critical sections were designed for. We also discussed a few times that there are more fine granularity mechanisms to accomplish mutual exclusion - for example, if the exclusion is only against one single thread of execution, then a mutex (if the other thread is a task) or a “surgical” diasable of a particular interrupt (if the other … 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 ().

WebJun 13, 2024 · Calls to taskENTER_CRITICAL () and taskEXIT_CRITICAL () are designed to nest. Therefore, a critical section will only be exited when one call to taskEXIT_CRITICAL () has been executed for every preceding call to taskENTER_CRITICAL (). That sounds like the opposite of nesting to me...but I just work here. IMO It is nesting (or re-entrant).
