Problem DescriptionI am having some trouble using HAL_UART_Receive_IT() to receive UART data in interrupt mode, the callback HAL_UART_RxCpltCallback() only triggers once for the first byte, subsequent bytes do not trigger the interrupt. I don't know ...
I am trying to switch the USB to DisplayPort mode via the PD (Power Delivery) line. I have a custom board based on the STM32G0B1CBT6, and another board based on the RTD2556, which works well for switching. I am sniffing PD communication using the LA1...
Hello!I am using STM32F427VIT6 and OV5640 camera to stream MJPEG to a webserver. I used DCMI DMA to get a jpeg_frame, size around 10KB to 25KB per image, with almost 30FPS and send it to jpeg buffer in CCMRAM like this.__attribute__((section(".ccmram...
Hi,I'm using the STM32H743, with TLV320AIC3254 audio codec to send and receive audio using the SAI peripheral in I2S mode, 16 bits (extended mode, i.e 32 bit slot), master, stereo.I'm using DMA to send/receive the data, but have come across an issue ...
Hello everyone,I am looking for a solution for a CustomHID device on a STM32C071.I would like to implement a CustomHID device, with TreadX and USBX.Unfortunately I can only find examples for mice in the templates. It is a bit difficult to deduce a Cu...
Hello,I am just trying to compile the example project GPIO_IOToogle_FSBL by using the STM32CubeIDE and firmware with its patch STM32Cube_FW_N6_V1.1.0.zip (i.e., en.stm32cuben6-v1-1-1 (patch).zip) and after following the instructions per "UM3249 - Use...
Greetings, I am using a Discovery Kit (B-U585I-IOT02A) and I want to use the LPTIM1 to wait 5 seconds (counting x ticks), at the end of the 5 seconds enter in a Callback to do something and then restart the counter again.I want to use as clock source...
We are using the STM32U575RIT6 device and performed a RX/TX swap on LPUART1, ports PC0 and PC1. When we enabled the Swap TX is properly transmitting out of PC0. But we are unable to read anything on the new RX pin PC1. Other than enabling the pin swa...
