It is enable ADC DMA interruption by default in the STM32CubeHAL library, why did you do that?I do not need the ADC DMA interruption, what should I do?Please help me, thanks.

HS in FS Unclear Functionality While Troubleshooting Issues

All,I am using an STM32F769 chip as a USB MSC Host. The device is fully functional with certain USB sticks, but not with others (typically works with 2.0 but has a range of issues with 3.0). Specifically, I am seeing that if I control the VBUS line v...

STM32F3Discovery power-up delay, MCO clock drop-out

When powering a F3Discovery (rev.D) board through the USB-USER port, there is a 2 second gap in the MCO clock signal (coming form the ST-LINK chip). See sceenshot1 (ch1=5V , ch2=MCO at SB12). When power is applied there is about 20ms worth of clock-c...
