Hi! I've got a very strange behaviour of stm32g431. Sometimes, when I plug my device into USB port, it doesn't start, becoming completely non-functional. When I try to reprogram it, openocd shows that device is protected
processing full erase cycle helps, but still have no idea, why device enters such condition!Please help!
Getting started with analog, STM32F769I-DISCO. undefined reference to wm8994_drv
I am trying this example on my STM32F769I-DISCO. I followed the given tutorial for adding the dependecy. wm8994 is in ../Components/wm8994/wm8994.h. But when building the code I am getting ../stm32disco/test2_audioread/Debug/../Core/Src/main.c:1263: ...
Resolved! STM32L010F4P6 which pins are used by UART bootloader
Hello, I'm attempting to flash firmware to aforementioned microcontroller using STM32CubeProgrammer. I have connected ST-Link VCP port to PA2 and PA3 ports, and i can communicate with my application fine. I even erased flash memory so I could be sure...
I have an issue with STM32L552 USB library. After sending an HID message once, the usb will send empty packets indefinitely (len=27, data len =0).
This is the data I recorded with WireShark. As shown in the picture, when I send HID packet once (len=91), the USB will send empty data packets indefinitely (len=27), then trying to send packets from host to device (out direction) will cause the tran...
