Today, I suddenly experienced a bus fault on my stm32h563 which I traced down toDBGMCU->APB1FZR1 |= DBGMCU_APB1FZR1_DBG_IWDG_STOP;which I use to configure the watchdog to stop when the core has been halted by the debugger. fault status registers:SCB-...
Hi,I would like to enable the SWO signal on the SWD connector, but one of the SDMMC data pins is already using that line. To avoid creating a long stub on the SDMMC bus leading to the SWD connector—which could cause line reflection issues due to the ...
Hello,I have successfully setup a virtual port and communicate from WebUSB/WebSerial and plain serial ports with my STM32F373. I'm now looking to implement Bluetooth to eliminate the need for a USB cable. What is the simplest way to add a bluetooth...
Hello , I am using the STM32G0C1RET6 MCU and want to generate the frequency in between 20Khz to 200Khz, with dutycyle in between 1 to 100%, but frequency below 10 percent is not generating, as my CCR value gets 0, due to low ARR value. Am I going in...
Hi,I'm trying to use SPI Tx DMA transfer on a Nucleo STM32H563ZI board connected to a LCD module that works on 3wire spi, so just 1Tx line. I know the SPI configuration and code for the LCD driver is OK because everything works if I run in interrupt ...
Hi,I am able to read the mcu temperature but I want to know the maximum worst-case time required to read the internal temperature of stm32h743.The clock for the ADC is configured as 76 MHZ. Does that mean that 1 ADC cycle is 0.013 uS (1/76M) ?#defin...
Hi STM32 Team,I am working with the STM32F7508-DK development board and interfacing it with an SD card using the SDMMC peripheral. The 1-bit data transfer mode works flawlessly, but when switching to 4-bit mode, the interface fails to operate as exp...

Hello,I need the BSD-File for STM32L151RCT6 for Boundary Scan. Does anyone know, where I can get it? In the recources section I can only find an older .zip file with bsd files for other processors.Thanks.
Hi. I am working on creating parallel threads on my STM32U5G9J-DK2 board using freeRTOS. Are there any freeRTOS example projects for this devkit I can reference? I could not find any while creating a project in the STM32 Cube IDE.Thanks, Michael
