freeRTOS the priority grouping problem

My brother once told me to learn attention to detail, I never seriously, the results are now fulfilled in me, maybe just write a static, it will cause the program to run it up; haunt you three or four days of issue Maybe not a problem but often you ignore the details!

Process now entered, in freeRTOS interrupt this has nothing to do between two and priority task priority, priority regardless of how many interrupts, interrupt priority is always higher than the priority of any task, that task execution in the interruption began to execute the interrupt service routine.

In addition to STM32F103, F407 and F429, the smaller value of the priority interrupt, the higher the priority. FreeRTOS the task priority is the task priority the smaller the value, the lower priority task. Therefore, the code will have freeRTOS in the following sentence

Today, when writing the microcontroller 107 basis timer freeRTOS code, ignore this, resulting in my program stuck, look for the issue of the day, the last packet timer into the following figure just fine.

I hope you pay attention to it.

If you like my blog, thumbs up trouble you to look at me the way, we will study together, share together, progress together.
