Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I'm really trying to tell if the board is connected to an external comm port to turn off usart sends so they don't potentially backup and slow things down. I know other products expose thinks like vbus sensing? Don't know much about it. I tried to...
I have an STM32F508 board and want to connect a USB stick. However, the stick is not recognized. I get the following messages in the debug messages:DEBUG : Cannot allocate memory for MSC HandleDevice not supporting MSC class.Tried it with the same se...
Hello,I'm trying to use the async Zephyr UART stm32 api, but I've encountered an issue. I'm using STM32F412.I'm trying to use the Zephyr UART stm32 async API(with DMA), with 3Mbps. I can see that the received data are correct so the baudrate/frame/DM...
I'm designing a board G4 MCU and want to be able to power the board from USB C as well as debug or program the board.Is it possible to program the MCU via the USB C or usb 2.0 interface? If not, and I have to use SWD, what would i need in order to pr...
using STM32CubeIDE, the ETH and LWIP are enabled, but no init file eth.c generated.The main.c includes MX_LWIP_Init(), but not MX_ETH_Init().Is it right?Thanks.JYI
Hi community. Greetings of the day!I'm using ThreadX RTOS thread to receive the data from USART and I'm sending it to the ThreadX queue & transmitting it to the USART(Tera-term display).What happening is that I'm using IT(interrupt) method to receive...
For the USBX ACM class, the ux_device_descriptor files are generated by CubeMX in USBX/App folder. When trying out the RNDIS class type, no files are generated here. Is this a bug or not implemented? If not are there any examples of this to read? B...
Hello,I'm working on STM32U5. We integrated the USB lib without AzureRTOS using the stm32_mw_usb_device (from STM github) as example.I use my STM32U5 as a USB device CDC, using the USB_OTG_FS. Everything seems to be working fine (Linux can mount it a...
Hello,We are using UART polling and had it configured using STM32Cube. That was great until we realised there wasn’t any built-in checks for parity errors, overrun errors, …. How come those errors seems to be checked within the handler when using non...
Looking at this post pwm and callbacksIt does indeed look like the PWM pulse callback is used rather than the HAL_DMA_XFER_CPLT_CB_ID CalllbackI have set up DMA to transfer to PWM. It is a circular buffer so I am just changing the pointer "audio_chan...
