Robert Fisk 2983da24b2 Changed Upstream and Downstream SPI transfers back to DMA. DMA works ... correctly now, either because SPI is in 16-bit mode, or because I found all the other bugs! Doubled SPI baudrate to 10.5Mbps. Transfer speed now limited (again) by Downstream's lack of FIFO buffering in the USB host controller. Also disabled DMA transaction half-complete interrupt in stm32f4xx_hal_dma.c, as it wasn't doing anything useful.		10 years ago
