Using a Nucleo-G431KB developoment board, I played a bit with UART RX DMA.I started a DMA RX on a linear buffer, and would stop and then restart the DMA.I just observed that after receiving a couple of bytes, HAL_UART_DMAStop no longer stops the DMA ...
I am trying to transmit/receive data via Virtual COM port in the STM32L5xx using the USB CDC libraries. I understand that the entry to the CDC_Receive_FS() would give me an entire packet of data that I enter on the serial terminal. I would like to kn...
helloWe have some problems to run the "32L496GDISCOVERY\Nx_TCP_Echo_Client" from the "STM32CubeExpansion_CELLULAR_V7.0.0" package (with AZURE RTOS).What we did so far: we changed the entries in "plf_cellular_config.h" to meet the requirements of our ...
There is a bug in STCubeMX regarding LevelX. After changing the settings in the Code Configurator (even those not related to system settings, only e.g. UART) the "lx_stm32_nor_custom_driver.c" file is being damaged. Namely, the content of our custom ...
Hello , I'm using Nucleo-G431RB board , and I am trying to flash the MCU via UART1 using PA9 and PA10 pins but I can't make it work .. I get an error like "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial ...
Hello. I'm trying to implement a laptop keyboard on a microcontroller. I can not find usb codes for some fn buttons. The usb protocol has descriptions for combinations of changing the display brightness, volume, media keys, but more is needed. Can so...
