* Add a work around to have each pio data change fiq followed by a regular IRQ ↵henryk2007-11-231-3/+0

| | | | | | | | | | | added during the last week) Change freertos code to not mask FIQ, this finally makes the FIQ working (with approx 700ns +/- 100ns latency; yeah!) and therefore reception starts working Change to two times oversampling (keep four times oversampling code ifdef'd, extract all the magical values to a header file) because at four times oversampling every other sample is very close to a possible data edge and therefore not reliable git-svn-id: https://svn.openpcd.org:2342/trunk@347 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

Lots of debug statements still in there git-svn-id: https://svn.openpcd.org:2342/trunk@335 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

Almost all of these have not been checked yet, I just copied them over and hot-fixed compile time errors F.e. all ssc usb code has been removed git-svn-id: https://svn.openpcd.org:2342/trunk@323 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
