14 | This script will program a T55x7 TAG with the configuration: block 0x00 data 0x00088040 | |
15 | The outlined procedure is as following: | |
16 | ||
17 | "lf t55xx write 0 00088040" | |
18 | "lf read" | |
19 | "data samples" | |
20 | "data pskdet" | |
21 | "data psknrz" | |
22 | "data pskindala" | |
23 | "data psknrzraw" | |
24 | ||
25 | Loop OUTER: | |
26 | change the configuretion block 0 with: | |
27 | -xxxx8xxx = PSK RF/2 with Manchester modulation | |
28 | -xxxx1xxx = PSK RF/2 with PSK1 modulation (phase change when input changes) | |
29 | -xxxx2xxx = PSK RF/2 with PSk2 modulation (phase change on bitclk if input high) | |
30 | -xxxx3xxx = PSK RF/2 with PSk3 modulation (phase change on rising edge of input) | |
31 | Loop INNER | |
32 | for each outer configuration, also do | |
33 | XXXXX0XX = PSK RF/2 | |
34 | XXXXX4XX = PSK RF/4 | |
35 | XXXXX8XX = PSK RF/8 | |
36 | ||
37 | In all 12 individual test for the PSK demod | |
