NUCLEO-H5E5ZJ — Redrawing the Schematics as a GPIO View

I have redrawn the NUCLEO-H5E5ZJ schematic as a personal exercise in understanding the architecture of the board and the STM32H5E5. I have consolidated the original multi-sheet design into a main STM32H5E5 schematic and a separate STLINK schematic,

Should i use single transfer mode instead of double buffer mode in DMA for my program?

Hello everyone,Actually I am making a data acquisition system in which my mcu takes analog data from a sensor and stores it in a buffer, and then into a 2nd buffer with the help of DMA in double buffer mode. Now i want to transfer this data via UART

Does MotionFX support multiple simultaneous 9X/6X instances?

Our application is an intelligent antenna pointing system that uses two identical sets of IIS2MDC magnetometer + ISM330DHCX accelerometer/gyroscope — one pair on our base board, and one pair attached to the moving gimbal. Our overall hardware design

STM32H755 DMA peripheral read timing differs from AN4031, actual hold time shorter, seeking explanation

Hello,I have recently tested the timing of DMA reading data from GPIO on an STM32H755 and found that the required input signal hold time is shorter than what is described in AN4031. I would like to ask whether my understanding is incorrect or if it i
