Resolved! DMA request generation on STM32H7

Hi!I am looking into the possibility on using LPTIM1 to trigger a DMA transfer with no CPU interrupt. This timer is chosen because it can be clocked directly by the HSE clock input. In the datasheet of STM32H7B3 (DS13139 - Rev 8) table 4, it states t...

DCMI and DMA to save multiple images on RAM

I'm currently evaluating the STM32U5 series to connect to a camera via DCMI and store video (i.e., multiple frames/images). For now, I would like to keep things simple and also learn how the DCMI and DMA workflow is like. So, I'll keep this forum pos...

Question about USB 2.0 HS support on discovery board

I need to do some testing with the STM32F767BIT6 MCU, to use the USB 2.0 HS USB peripheral. I can see it's used on this dev board ( https://uk.farnell.com/stmicroelectronics/nucleo-f767zi/dev-board-nucleo-32-mcu/dp/2546569 ) but the data sheet states...
