Hello Xiang Xiao,
The DWT_CYCCNT register provides the high-resolution time I need.
Thanks for the solution!

Hi Jiawei Wang
I have a similar requirement. The solution with SysTick and a little
tick in configuration used through semaphores, doesn't solve the problem
in a good way: shorter sampling times (<500us) are difficult to obtain,
in particular in pysimCoder generated code. This is my experience
Hello everyone,
I am currently developing on an STM32H7 board using NuttX and am in need of a
high-resolution timer to profile my program.
A timer with microsecond resolution would suffice.
My initial approach was to utilize one of STM32's timers configured in 1MHz
auto-reload counter mode, an
