Hello, I'm working on STM32H743BIT6, It is in production phase. During flashing the software, it is failed to configure LSE crystal with internal RTC enabled. out of 50 boards 2 board got failed.During debug it is observed that the RTC clock configur...
@Erwan SZYMANSKI I am trying to establish SPI communication between two STM boards: the Nucleo G431RB as the master and the STM32MP157F-DK2 as the slave. I followed the instructions provided in the Getting Started with SPI guide and configured the se...
Hello All, I need to design a board that will carry an IS42S32400F-6BL SRAM ,STM32H750XB MCU,Flash MT25QL512ABB1EW9-0SIT and Couple of support components along with Power supply.My questions-1) MCU Power Supply Protection2) High frequen...
Hello everyone! I want to use some MOSFETS to individually power up/down sensors on a PCB. Here's the schematics : The MOSFET is a DMG1012T-7 (N-Channel) and here's it's datasheet : https://www.lcsc.com/datasheet/lcsc_datasheet_1809050424_Diodes-Inc...
I'm working on a project using the STM32H563RIT6 microcontroller where I need to receive data over UART using DMA with idle line detection. The data is sent from a Python script using 'pyserial'. My setup is as follows: typedef enum{ IDLE, SE...
I am trying to use ADC with DMA on STM32H743XI. I set up ADC1 IN7~IN9 and use three uint16_t to store their converted values. I use DMA2 Stream 0 to transfer data. CPU ICache and DCache as well as MPU are disabled. ADC Clock Mux is set to PLL2P 50MHz...
Dear, I am trying to run the CAN Communication in STM32F407 discovery board, In CAN_INIT I have made controller state to Ready after that I have changed the controller state from ready to LISTENING in CAN_START function, but when I am trying to exe...
Hello,I tried to set a capture/compare register to a value beyond that of the auto-reload register, and the timer I used (TIM8) behaved as if the value had not been written. Reading back gives the expected value though. I haven't dug more but I'm cur...
Hello,I'm trying to use a STM32H743XI to run a 1280x800px LCD display. I'm using an external 32bit SDRAM (IS42S32200L) running at 110MHz.The active framebuffer (RGB565) is located in the first SDRAM bank and I can display a stable image with LTDC clo...
[Not a bug report, explanation below, first post kept for context]I'm writing a USB host library for the STM32H743 rev V. Bits PENA and PENCHNG of register OTG_HPRT represent Port enable and Port enable/disable change. Port enable is supposed to be a...
