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 ...
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 ...
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...
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; ...
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 ...
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...
IS61WV25616MEBLL and IS64WV25616MEBLL are recent Muxed PSRAM from ISSI. I would like to use these with an LQFN100 STM32H750VBTx to avoid complicated routing with SRAM and going to a larger LQFN or BGA package.The FMC of this MCU supports Muxed PSRAM....
Hi,While working on the code for an STM32H7B0, I'm having issues with the blanking function of COMP1. Specifically, it works correctly when the comparator is in non-inverting mode, but if I invert the comparator's output (to detect falling thresholds...
I wrote a code for this microcontroller to test the CAN protocol, and it worked successfully in loopback test mode—data was transmitted and received correctly without using any external CAN transceiver. Then, I switched the CAN mode from loopback to ...
Hi All,I have written a baremetal code to initialize the USART2 of STM32F401RE and print HELLO WORLD. The code does not use HAL and rather accesses and writes to USART2 peripheral registers using the C pointers. I have cross verified the code multipl...
