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, but
I'm still waiting for a better solution.

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, and then combine the counter register value with the
SysTick value to derive a time measurement. However, this method feels somewhat
hacky and bypasses the OS's abstraction layer, which I prefer to maintain.
As I am relatively new to NuttX, I am unsure of the conventional method within
NuttX to achieve this functionality and have not found relevant examples. Any
guidance or pointers would be appreciated.
Thank you,
