Resolved! STM32H755 WWDG interrupts
Hy every one,I'm facing up the WWDG usage on a STM32H755 MCU.I noticed that WWDG peripheral has 2 interrupts: normal one and the early wake-up EWI one.What is the difference?Manual is not clear! Thanks in advance
M0 in-line assembler moving from bootloader to main app
Folks,I have a bootloader for an M0 which works without using interrupts. It works in that it loads the new app, the CRC in the new app matches and I then try and jump to 0x8004000.In the past I have used a couple of different methods with M3/4 to bo...
Resolved! UART with DMA, not working with TCIE (Transmission Complete Interrupt Enable)
Dear together, For the past dew days Im stuck kwith UART communication with DMA.To start with, I am implementing TX now. Later I will implement RX. I have managed for TX to work without interrupt. As per my application, I need Interrupt to inform the...
HAL_FLASH_Program problem on STM32C071CB
I'm using HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 32-bit-addr, 64-bit-data) and it crashes with an 0xfffffff7 exception. Has anyone else seen this? I've checked that the addresses are aligned to 64-bit boundary.
Resolved! No CAN Communication on STM32H723ZG-E01 (A230801274)
Dear STMicroelectronics Support, I am working with the STM32H723ZG-E01 board (Serial: A230801274) and encountering an issue where CAN communication is not functioning as expected. Based on the documentation, I have configured the FDCAN1 interface to ...
STM32H7 Max UART Baudrate
Posted on November 24, 2017 at 16:15I tried to figure out the specification of the max. UART baudrate for the SM32H7 series (@ 400MHz system clock).The data sheet says 12.5 MBit.Does this apply to all UART ports or only selected ones?I need 8 MBits ...
Resolved! STM32F723x USB HS CoreReset Issue
Hello, for the last couple of days I've been trying to set up my STM32F723ZET6 project as a USB HS CDC device with internal PHY.My code gets stuck in this loop do { count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; ...
STM32 Boot mode Pin functionality
Hi,I’m currently working with the STM32G491RE MCU and have encountered an issue related to GPIO pin PB6.In our normal user application, PB6 is configured as a push-pull output. However, we would like to understand its behavior when the device enters ...
Resolved! STM32H7 FMC - SDRAM byte and bit swapping
HiI am working on a project with an STM32H743 and a 32-bit SDRAMThe FMC signals are quite randomly scattered across the package and this makes layout quite convoluted and difficult. I'd like to swap byte-lanes and individual bits within each byte, fo...
