Hi,I am trying to setup an USB HS CDC example with NUCLEO-H7S3L8.After setting up the projects for both CDC_Standalone and NUCLEO-H7S3L8 board example (for the latter I manually enabled the USB HS Device from CubeMX), I successfully ran each example ...
Dear All,I am interfacing my STM32U5G9 device with VS1011 audio decoder, over SPI using DMA.My setup mostly works, I can configure the decoder send and receive data from the chip.But over a long period of time (hours of having the device running) I a...
Hi everyone,I faced a frustrating issue with lwip_connect() hanging forever when trying to use an STM32 as a TCP client (FreeRTOS V1 + LWIP stack). 易 Problem SummaryCalling lwip_connect() inside my STM32 TCP client code caused the system to hang inde...
I've inherited some code, the original owner is long gone, and I'm trying to understand his code which has ZERO comments (I'm sure I'm not the only person who's been in this position)It's using the STM32H747IGT6 so it's dual core, got one M4 and one ...
