* Revamp SSC buffer handling, should severely reduce buffer leakagehenryk2007-12-051-42/+25
| | | | | | | | Switch SSC IRQ handling from edge triggered to level triggered. Somehow I was losing the ENDTX interrupt otherwise Modified ISO14443 code for testing to enable repeated REQA->ATQA cycles. Somehow only the first ATQA is correct, subsequent ATQAs are missing the first two bits. Need to debug git-svn-id: https://svn.openpcd.org:2342/trunk@373 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
* ATQA needs to be transmitted with parityhenryk2007-12-031-1/+1

| | | | | | | | | | | 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
