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

Missing bootloader command

The AN3156 explains on page 18 the Read Unprotect Command:This command is selected when wValue = 0 and the first byte of the buffer sent by the host is 0x92. The buffer length is only one (the command) byte.The host sends a DFU_DNLOAD request with th

STM32C071 clock config problem in CubeMX

Hi ST,I’m trying to configure the clocks for the STM32C071GBUx MCU in CubeMX (latest version, 6.17).This MCU has two SPI interfaces, two UARTs, and two I²C peripherals. However, CubeMX only allows me to configure the clock for one UART, one I²C, and

How to Use an STM32 Microcontroller for Smart Home Lighting Control?

I’m exploring ways to use an STM32 microcontroller for a smart home lighting project. The goal is to control multiple lights while monitoring switches and sensors, with reliable communication between the controller and other devices.I’m considering u

CAN communication not working on STM32H723ZG

I am using a STM32H723ZG and a jetson orin nano in my project. but to communicate between them i am using a sn65hvd230 CAN module and have chosen pd0 and pd1 as fdcan_rx and fdcan_tx. i have tried several times but for some reason when i have alreay

STM32U5G9J-DK2: What size are the bolts holding the boards/display PCBs?

Hi all,I have this kit but I don’t have any bolts holding the display PCB to the main PCB. I tried to look at the BOM for a reference to the part number but I don’t see anything for the bolts. I took one of the bolts holding the standoffs to the main

problem is with placing the crystal on the PCB design.

Hi, I'm new to PCB design. I'm planning to build a handmade board for a project that uses the STM32F103C8T6, and I've run into some issues in certain parts of the PCB design. My board only has copper on one side (single-sided). For the HSE 8MHz and L
