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 ...
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 methids with M3/4 to bo...
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...
Will STM32H743BIT6 support only OTG_HS mode? Will it support normal USB operations by disabling OTG option? If yes which pin will control that functionality?
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...
Hi everyone,I have STM32 Nucleo F767ZI Board and OneRNG V3.0 by Moonbase. OneRNG is using USB Serial Protocol. When I connect OneRNG directly to PC through USB connector, open it's COM Port on Serial Monitor like Putty, send CMD "cmdO", it starts giv...
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 ...
