This script will program a T55x7 TAG with the configuration: block 0x00 data 0x00088040

The outlined procedure is as following:

|
|
|
"lf t55xx write -b 0 -d 00088040"
|
|
"lf t55xx detect"
|
|
"lf t55xx info"

Loop OUTER:

change the configuretion block 0 with:
|
|
-xxxx8xxx = PSK RF/2 with Manchester modulation
|
|
-xxxx1xxx = PSK RF/2 with PSK1 modulation (phase change when input changes)
|
|
-xxxx2xxx = PSK RF/2 with PSk2 modulation (phase change on bitclk if input high)
|
|
-xxxx3xxx = PSK RF/2 with PSk3 modulation (phase change on rising edge of input)
|
|
Loop INNER

for each outer configuration, also do

XXXXX0XX = PSK RF/2

XXXXX8XX = PSK RF/8
