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...
Resolved! Can't communicate with another device via UART
I've been fighting this problem for some time. I have a simple custom made board based on STM32G05. I'm utilizing 2 UARTs. One of them I use just for serial port debug. Takes keyboard input (but don't use it) and print out data for debugging. The ...
Resolved! STM32 Bus Matrix behavior and arbitration mechanism
Hi,I'm trying to learn DMA in depth, but I'm confused at some points. It's about Bus Matrix and Arbitration mechanism. In STM32F446RE, there are 2 DMA controller and each one has 1 peripheral bus and 1 memory bus. Question is not about memory bus of ...
