HAL_GetTick() and xTaskGetTickCount()

Posted by spflanze on 2016-01-09 01:24

I am using a STM32CubeMX version 4.12.0 generated files with the FREERTOS option enabled.

I cannot find any information about HAL_GetTick() in the doxygen generated documentation. A search for this in this documentation’s Main Page’s search function does not get any hits. Also, I cannot find a definition for this function in the generated code. I can only find its declaration in stm32f3xx_hal.h. And so this leaves some questions unanswered about it.

What is its unit of time?

Why can’t I find its source code?

How similar is HAL_GetTick() to the FREERTOS function xTaskGetTickCount()? Under which circumstances would it be appropriate to use each of them?

I made some changes to doxygen configuration and was able look up the source code and documentation for HAL_GetTick() in file stm32f3xx_hal.c. There I found the default unit of time is the millisecond.

I do not know what change in the doxygen configuration made HAL_GetTick() available to be looked there.
