Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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,how am I supposed so handle the reinsertion event while using the FileX with an SD card? All the examples I saw assume the SD card cannot be ejected while in use which is obviously unrealistic.I tried to do it according to the official docs and wh...
in HS, HAL_PCD_Init fails with timeout in USB_CoreReset Hello everyone,I am working with an STM32H7S78-DK and I’m trying to use USBX in standalone mode for a composite USB device (CDC ACM + PIMA) over USB_HS at 480 Mbit/s.At the moment, I have only ...
Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebu...
I have looked https://community.st.com/t5/stm32-mcus/implementing-uart-receive-and-transmit-functions-on-an-stm32/ta-p/694926 and https://wiki.st.com/stm32mcu/wiki/Getting_started_with_UART#Configure_UART_Interrupt and tested sending tx data with a S...
Hello, I am using HAL2 and wrote the basic code below: while (1) { HAL_GPIO_TogglePin(LD1_PORT, LD1_PIN); HAL_Delay(1); } I looked at the pin with an oscilloscope and I see that the signal stays 2ms low and 2ms high. If I change the code t...
Hello, I used STM32CubeMX2 to configure a timer (timer 2, channel 4) for input capture. I'm starting the timer and then applying the signal on the timer input pin. Since I configured the TIM interrupt, the interrupt callbacks do occur. void HAL_TIM...
Hello,I am working on USB device CDC ACM for STM32N655L0. I found an example about "Ux_Device_CDC_ACM" for NUCLEO-N657X0-Q. Can I use this example for my mcu? How can I find ioc configuration of this example?I also tried to implement this example to ...
e.g. select I2S with "Master transmit" which should only use I2S_CK, I2S_WS and I2S_SDO, yet the I2S_SDI pin is also muxed and blocked for other use (and both DMA directions are available)
Hi Team,We are planning to use an STM32 camera interface over USB using the UVC protocol in our upcoming design. We would like to understand if there are any evaluation or development boards available that can be used for initial testing.Our key re...
