* Fix sendinghenryk2008-03-091-1/+1
| | | | | | | | | | | Add Tx abort and SSC reset functionalities There is a bug workaround for a peculiarity in the SSC Tx: When it is set to START CONTINOUS while a transmission is in progress (started by START TF RISING EDGE, which is necessary for the correct timing) it will lose one (or two?) bits of sample data. The resetting of the start condition itself is necessary because the SSC will only transmit up to 64 bytes (32 bit times 16) per start condition Add performance counters for sent and received frames git-svn-id: https://svn.openpcd.org:2342/trunk@445 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

* Implement transmissionhenryk2008-03-031-2/+1
| | | | | | | | Implement a 'pretender' for PoC: Since Rx is not working properly we'll just pretend to have received something based on the approximate length. Clarify length calculations in machester encoder and remove obsolete test code git-svn-id: https://svn.openpcd.org:2342/trunk@437 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

* Revamp SSC buffer handling, should severely reduce buffer leakagehenryk2007-12-051-0/+3
| | | | | | | | 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

* Commit status quo (pending cleanup of the debug and experimental code that I ↵henryk2007-11-231-0/+11
| | | | | | | | | | | 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
