Robert Fisk	58308c4a89	Added Mozilla Public License information to file headers. ... Mozilla Public License v2.0 is compatible with the various licenses used by ST and ARM.	9 years ago
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

Robert Fisk	d48815d8d9	IT. WORKS. !!!!!!!	9 years ago
Robert Fisk	ce03845623	Completed moving Upstream to interrupt-based SPI. ... Although I am not entirely convinced this is necessary, as the SPI data stall issue only appeared with optimisation off (-O0). Perhaps re-visit this if Upstream needs more free CPU time later...	9 years ago
Robert Fisk	b9cc31d036	Crazy hardware issues, about to revert Upstream SPI from DMA to ... interrupt transfers	9 years ago
