STM32H747 USB audio DataOut issue
Hi together,I'm trying to make a basic USB audio speaker from STM32H747 DISCO board with Cortex-M7.I start a new CubeMX project for this board, add in the USB_HS and audio drivers on default settings.Once I do this, the Windows 10 machine will see th...
Resolved! How can I program and / or debug the microcontroller of a NUCLEO-H743ZI2 without the CN1 micro USB connector?
Hello Community,I have a curiosity to ask you. I have a NUCLEO-H743ZI2 without its micro USB connector (STLINK-V3E USB connector CN1).I would like to know if it was possible to continue programming and debugging on the microcontroller integrated into...
32F417 RTC errata sheet if reading subseconds - is this code ok?
I am referring to the bug whereby the shadowing of the date/time registers is very occassionally broken if the sync prescaler was read beforehand.That reading order is exactly what the ST HAL functions do. See below.HAL_RTC_GetTime reads the SSR and...
