- add new DAC driver (instead of poti) for PICC
- DFU: put all DEBUG_ defines in "#ifdef DEBUG" enclosure - alter GPIO defines for new OpenPICC v0.4 prototype - add new AT91F_DBGU_Fini() function - take care of new inverted USB pullip in OpenPICC v0.4 prototype - fix typo in 'opicc_reg_write' macro - add some more PICC related SSC code NOTE: this firmware is the first version that will _NOT_ run on a OpenPICC v0.3 anymore! (All changes by Henryk Ploetz) git-svn-id: https://svn.openpcd.org:2342/trunk@283 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
