How read STM32 HRTIM master timer current counter value
The STM32 HRTIM (high resolution timer) provides a high speed counter that is suitable for benchmarks due to its high counting frequency of up to 240 MHz on the STM32H743.
You can read its current counter value using
example.cpp
uint32_t t0 = HRTIM1->sMasterRegs.MCNTR;
