Robert Fisk 2e3293e84f Increase SPI interface speed 4x, to 5.25Mbps. Required modifications to ... SPI peripheral library. At this speed SPI requires ~60% CPU time at -Og optimisation level. This could be further improved by trimming down the SPI interrupt. But... Speed is now limited by Downstream's single-packet-per-URB restriction, to about 460kB/s. USB Middleware does not implement TX FIFO empty interrupt, so a bit of work is required here.		9 years ago
