Hello,

Your SW Task has lower priority than Main and ADC ones, thus it is quite difficult to get CPU time by this task. Have you checked how much time you need to one loop of each task function?

sprint and printf functions are quite heavy in terms of execution time.

Hey Artur I,

i modifed the code by setting SW task priority as Main and ADC tasks,

i also use mutex when trying to access to the queue, and change Main Task periode to 100ms.

and now i get this result:

Hey from SW Task; cnt2= 1

Hey from ADC Task; cnt1= 1

Hey from SW Task; cnt2= 3

Hey from ADC Task; cnt1= 2

Hey from SW Task; cnt2= 5

Hey from SW Task; cnt2= 6

Hey from ADC Task; cnt1= 4

Hey from SW Task; cnt2= 8

Hey from SW Task; cnt2= 9

Hey from ADC Task; cnt1= 5

Hey from SW Task; cnt2= 11

Hey from SW Task; cnt2= 12

Hey from ADC Task; cnt1= 7

Hey from SW Task; cnt2= 14

Hey from SW Task; cnt2= 15

Hey from ADC Task; cnt1= 8

Hey from SW Task; cnt2= 17

as you can see their is data lost on SW Task.

also how can i checked how much time it need to one loop of each task function?

Hello,

Usually I am using a standard ping toggling (HAL_GPIO_TogglePin() of one of the remaining pins) or I am using EVENTOUT function of the pin (it is connecting the pin to the core, and once you execute 'sev' assembly instruction you will see a pulse on all of the pins configured to EVENTOUT configuration.

I am attaching you modified code (main.c file -> please have a look at StartSW_Task() function and

#stm32cubemx
