Does HAL_GetTick() return ticks or milliseconds? (and how to measure in microseconds)

Question

I\'m new to using HAL functions. The description of the function HAL_GetTick() says that it \"provides a tick value in millisecond

Answer 1

When viewing my debugger, I can see I have available the uwTick global variable which seems to be the same as the result of calling HAL_GetTick() against my own defined global variable.

As per the docs:

void HAL_IncTick (void )

This function is called to increment a global variable "uwTick" used as application time base.

Note:
In the default implementation, this variable is incremented each 1ms in Systick ISR.
This function is declared as __weak to be overwritten in case of other implementations in user file.
