I have a plan to make a high-end grblhal development board based on the stm32H7 series chips, and sell it for people to study, but after my test, it only has a single-axis maximum stable output of 500KHZ, (STM32F446 is 400KHZ), a little discouraged, there is no reason to compare with The performance advantage made it, I don't know where is the problem, I downloaded the early H7 driver file and the early grblhal core, the file is about March 2022, I don't know if it is the reason,
