* Add T/C based receiver code with integrated miller decoderhenryk2008-03-141-30/+41
| | | | | | | | | Integrate T/C receiver into iso14443 layer 2a Add state field to iso14443_frame, rename ssc buffer state constants Sniffer seems to work with the new code git-svn-id: https://svn.openpcd.org:2342/trunk@452 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
* Fix sendinghenryk2008-03-091-0/+10
| | | | | | | | | | | 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

* Sending seems to be reliable now.henryk2008-03-031-1/+5
| | | | | | | Once in a while (about 1 in 20) there's an error condition that's not being recovered from, need to investigate git-svn-id: https://svn.openpcd.org:2342/trunk@438 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
* Implement transmissionhenryk2008-03-031-8/+84
| | | | | | | | 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
