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...
Hi all,I'm having a go at programming on the STM32N6570-DK. My goal final goal for this little project is to show the difference in pixel values between the first frame and current frame. This is usually done in vision systems to "filter" out the sta...
Hello,I have a custom board based on the STM32U5A5 microcontroller. I am trying to run a fingerprint reader sensor over USB on this board. For this project, I am using USBX Azure RTOS.The configurations I made on the CubeMX side are as follows:High S...
Hello Team, I want to connect a USB camera to an STM32H7 board. My STM32H7 supports USB OTG/Host. Is it possible to interface a USB camera with STM32H7?Does STM32H7 support USB Video Class (UVC), or is it better to use a DCMI parallel camera instead?...
Hello, I have a device with a variable message stream in UART and there is the issue that I cannot know when it's stream ends due to gaps (so a single ReceiveIdle won't work). The device has clear framing via an interrupt so I use that.The final syst...
I have a STM32F427 bootloader code, the jump from bootloader to application is working before enabled IWDG. The IWDG configuration is as followings: - hiwdg.Instance = IWDG; hiwdg.Init.Prescaler = IWDG_PRESCALER_256; hiwdg.Init.Reload = 1000; // 8S, ...
In my test environment, STM32H7S3Z8T6 works as the I3C controller and talks to the STM32H5 (I2C slave). The goal is STM32H7 will send out the entire SETDASA bytes at Legacy I2C speed, once STM32H5 receives the I2C speed SETDASA bytes, it decodes the ...
Hi, During the development of a bare-metal driver for USB CDC (virtual com port) in device mode i noticed an unexpected behaviour when trying to configure the USB Core to do a transmission of a multi packet message. I've got the following code which ...
Hi,I have a question regarding the STM32N6 BootROM flash boot process.My understanding is that the BootROM loads the FSBL from an external XSPI flash device. However, it is not clear to me whether the BootROM:Uses a fixed XSPI/XSPIM configuration (fo...
Hi, I want to use my F072's DACs to output a sin and cos signal. to save on memory I want to have only one buffer holding the values of a SIN function, COS values should be taken from the same buffer. Basically, I need the DMA for channel 1 to start ...
Dear ST experts,I have configured UART (both RX and TX) in Normal DMA mode. I want to send a small data packet every 500 ms with using HAL_UART_Transmit_DMA (&huart, buffer, 10). But I noticed that only one shot is triggered. What is the problem? Sho...
