I am using an STM32L151VET7 as a full-duplex SPI slave, and after using HAL_SPI_TransmitReceive_DMA and receiving/transmitting any number of bytes, the SPI remains busy, and further calls to HAL_SPI_TransmitReceive_DMA return HAL_BUSY. Upon transmiss...

Hi all,I'm using a 480 MHz STM32H753 uC for a graphics project, and I'm trying to use a very fast PWM signal. I can achieve a 5 MHz square wave that is relatively clean, but when I up that to 10 MHz it's clear that the rise/fall times are too long, a...
