Resolved! Difference between DMA normal mode and circular mode - using SPI to sample a fast signal
Dear all. I stumbled across something I don't really understand. I'm trying to detect a signal using SPI1 on STM32f723 as fast as possible and fill a buffer. I configured SPI1 in SPI_DIRECTION_2LINES_RXONLY mode, set prescaler to SPI_BAUDRATEPRESCALE...
