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 ...
STM32H7RS MCE
Hello,I have a question about the usage of the MCE in the STM32H7RSI have the STM32H7S78-DK boardI'm starting with a project that show images to LTDC with images on the flash (copy with DMA2D) and the framebuffer is on the PSRAM.My project works with...
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 ...
