Yann GASCUEL	38d49097f9	iso15 sniffing: intragrate 2SC sniffing in same FPGA mode ... switching Fpgamode while sniffing with FpgaWriteConfWord() was sometimes too long so the tag answer start was lost. Now, (only with FPGA_BITSTREAM_HF_15) with "FPGA_HF_READER_MODE_SNIFF_AMPLITUDE | FPGA_HF_READER_2SUBCARRIERS_424_484_KHZ": the amplitude is shrank from its 2 LSB bits and those 2 bits are now used to return the current frequency. From my tests, this 2 bits reduction does not affect quality of 1SC sniffing, but it may have slightly reduced the receiving range. FPGA FSK decoding code is also improved.	2022-03-08 10:11:14 +01:00
