What is the efficient way to measure the time taken by ADC DMA conversion?

I toggle a GPIO pin in the ADC call back function, I get time values on the oscilloscope close what is the supposed to be according to the datasheet, is that correct and efficient? Is there a method better maybe?

Bonjour,j'ai un système communicant avec des cartes identiques possédant des modules STM32F411 CE8 black pill . une carte est maitre et les autres cartes sont toutes esclaves. je suis en mode "UART_TwoBoards_ComPolling"mon IDE est STM32IDE avec les ...

STM32L0 Current Drive for GPIO in STOP 0

Hello:Hoping to find out the answer to a question that I cannot find in the data sheet for the part. What is the the drive current used to keep a GPIO pin enabled (SET) while in STOP 0? Page 65 of the data sheet indicates a value of 2.5uA/MHz in ran...

STM32H743 - NUCLEO SPI-DMA not working - always busy

I have attached my sample project with STM32H7https://1drv.ms/u/s!AuUAN7PWAxFS8l9pJ-mzXLp1vpXc?e=oFnJSXIn short, The basic function HAL_SPI_Transmit(&hspi1, aTxBuffer, 2, 1) work fine but it took a long time.For that reason, I tried to use HAL_SPI_Tr...

Hi, I want to write scrolling data to RTC Backup reregister. But how can I do this, I have no idea. I looked at the hal library but it doesn't support float data.

Moving SystemClock_Config Causes Strange Erros

I know this is a vague question, but it's a very strange problem I'm facing. My application (based on STM32G0) is working fine. I used CubeMX to autogenerate all the code, and have been building on top of it. Now I am looking to clean things up a bit...
