Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Recently I’ve been developing a host application on a Mac Mini (Apple M4, Sequoia 15.5) using Xcode. It communicates with a STM32H7 board via USB CDC, using the internal PHY at 12 Mbps. The USB CDC code is auto-generated by CubeMX with all default pa...
Hi, I assume there have already been posts on this topic, but I can't handle this problem. I have an STM32F429I-DISC1 board and I'm trying to connect it as a USB HID keyboard. Unfortunately, all the guides and articles don't work, and my board isn't ...
Hi, I'm working on STM32H7A3NIH6Firmware Package: STM32Cube FW_H7 V1.11.2 I have a very interesting issue with bootloader jumping.According to the file "an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics", the bootloader address ...
I have an STM32H735 Discovery Kit and am running the example LWIP code from STM32H7-LwIP-Examples/STM32H735_Disco_ETH. This works great. But, when I add MDNS, I get a very curious crash.I enabled MDNS in CubeMX, and then created a new thread to wait ...
HiI'm having troubles programming the stm32h755zit6 on my selfmade PCB. The schematics should be right, as i am able to programm the STM32. But if i run a simple code inwhich a certain pin should be pulled up high, it just won't work. Therefore I tho...
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...
