Observing the different execution time for a function if placed at different code memory location on STM32F765NIHx controller

e.g: Below are the execution time of memset() function at different locations.1. memset() plcaed at 0x0000000000219e96 : Time = 57.10 usec for 3k buffer size.2. memset() placed at 0x0000000000219d42 : Time = 28.66 usec for 3k buffer size.- memset is ...

RTC criteria for activating CSS

Hi ST Community.A colleague and I were having issues on an STM32L4, in that the CSS detects an LSE failure and swaps to the LSI.We looked at Errata ES00335 - Rev 15 and it confirms what we see that the LSI becomes unstable. We're looking for a workar...

Synchronization of timers in stm32f7

Hi Sir / Madam,I am trying to synchronize two timers or reduce delay between two timer outputs.Yellow signal represents low frequency signal ( Timer 3 around 4Khz ) and blue signal represents high frequency signal ( Timer 1 around 1.5Mhz ). They are ...

How can I get minimum nanosecond delay with a Nucleo F446RE using a Cortex M4 180 Mhz?

Hi everyone,I am using a nucleo F446RE using a Cortex M4 180 Mhz, and I have a problem when I try to get nano second delays.void delay (uint16_t delay)   {   __HAL_TIM_SET_COUNTER(&htim1,0);   while(__HAL_TIM_GET_COUNTER(&htim1)<delay);       }In t...
