* code deduplication. Use functions from iso15693.c * speedup CodeIso15693AsReader() * invert reader command coding. 0 now means 'unmodulated' ( = field on) * decode SOF only as a valid tag response in Handle15693SamplesFromTag() * complete decoding of EOF in Handle15693SamplesFromTag() * determine and write correct times to trace * FPGA-change: generate shorter frame signal to allow proper sync in StartCountSspClk() * modify StartCountSspClk() for 16bit SSC transfers * whitespace in util.c * add specific LogTrace_ISO15693() with scaled down duration. Modify cmdhflist.c accordingly. * allow 'hf 15 raw' with single byte commands * check for buffer overflow, card timeout and single SOF in 'hf 15 raw'
