Hello,We currently have a board with the STM32H753XI Rev.Y MCU.We're building a new revision of the board, and saw that there is a new STM32H753 revision (Rev.V). This revision has significant changes.There is no new part number for the Rev.V devices...

Problems with UART4 on the Nucleo-F429ZI

I'm working with the Nucleo-144 (STM32F429ZI) on a multi sensor system. I am developing using STM32CubeIDE.One of our sensors communicates over UART and we have broken out UART4 such that PC10 is TX and PC11 is RX. This configuration is suggested as...

I have managed to get ADC working in Interrupt mode and can read the three sensors values into a buffer called ADC3_VALUES[] on each of 3 callback events triggered by the ADC..../* USER CODE BEGIN 1 */void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* ...

What online training course should I take for stm32f4 series?

Does input frequency matter for smooth digital calibration

Hi, does input frequency have effect on the smooth digital calibration period since in the documentation(screenshot attached) it says the calibration is performed during a cycle of 2 to the power of 20 which amounts to frequency of 32.768 x 32 . Does...
