I'm trying to control the timing of ADC for best performance.So, I want to give exact delay based on the number of clock cycles. However, I don't know what API should I use to give delay.Right know, I turned on TIM16 and I know how to get timer like ...

Reset pin goes down every 400ms for 50us

Hi,we have problem with our custom designed board. We are using STM32L011F4P6 MCUs and some of them behaves very strange. After reset, every 400ms for 50us, reset pin (which is internally pulled up), goes down. We don't known what causes that behavio...

Resolved! I recently ported my STM32F413 (run at 100Mhz) application to a STM32H7A3 (run at 280-Mhz). But my DSP routine does not run 2.8x faster. Anyone has any idea how this happened?

I measured the time took to run a length 127 Multiply–accumulate routine by togging a GPIO pin before and after the arm_dot_prod_q15() routine. And then I can measure pulse width by a scope. It was 7us on the STM32F413 and 6us on the STM32H7A3.
