Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Can I use STM32F401RCT6 to be I2C master and slave at the same time?1: For the Master, I use I2C1 -> pin PB6 and PB7, I will read data from the current sensor ICs.2: For Slave, I use I2C3 -> pin PA8 and PC9, I will send and receive data from another ...
Hello.I have some questions while testing a product using the 107MCU.As the title suggests, when I set up FreeRTOS and create a task, the commonly used callback functions cannot be called:void HAL_SPI_RxCpltCallback(SPI_HandleTypeDef *hspi) void HAL_...
Hi,I'm trying to get the infamous Synopsys OTG module to work. I'm not using the STM32Cube libraries, instead I'm rolling my own HAL based on the reference manual, which, as some have noted elsewhere in this forum, is pretty bad.Currently I'm stuck b...
Hi,With the latest CubeMx (6.9.1), when calculating the consumption of STM32U535VET6Q, the peripheral consumption is not taken into account in STOP/STANDBY/SHUTDOWN modes. It only seems to work with RUN/SLEEP modes.Thanks
Hello,I'm trying to use FatFS with both USB HOST MSC class and SDIO.FatFS always tries to access the SD card whatever the drive number used in f_mount.May be I'm wrong with the path I use to access the devices : "0" for SD card, "1" for USB.Any help ...
Hello,I'm developing a USB-Host application (MSC / Fullspeed) with the STM32H743 µC (using STM32H743I-EVAL2 Board)The application works fine when using PLL3Q as clocksource.But when I use PLL1Q or RC48 as clocksource the USB "Core soft reset" timed o...
I'm wondering if this is caused by the use of a usb type-c connector. Is there recommended wiring for how to connect a type-c to STM32 processors while retaining the ability for dfu functionality? Note that for BOOT0 R30 has been modified to be 0 ohm...
I've been trying for a while to get DMA working on SPI, it returns an error when i poll the DMA so it stays in the while loop but I can't seem to figure it out and there is not much Info that helps me. Maybe someone can help me to get it working, my ...
Hi.I am trying to configure a timer with PWM in one-pulse mode (TIM5) as slave of another timer that sends N pluses to trigger TIM5.I am unable to do it could you give me a hand to understand what I am doing wrong?TIM1 when started should triggers an...
I am trying to use the HAL driver - HAL_I2C_MEM_READ(....)The stm32 is the master and there is a slave i2c device that I want to read from. The I2C transaction goes like this: <start> <dev address> <register that I want to read address> <start> <dev...
