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

The outlined procedure is as following:
|
||||
|
||||
"lf t55xx write 0 00088040"
|
||||
"lf read"
|
||||
"data samples"

"data psknrz"
|
||||
"data pskindala"
|

"data psknrzraw"
|

|
||||
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

XXXXX4XX = PSK RF/4

XXXXX8XX = PSK RF/8
