Many exisiting LUA scripts are using bit32 which has been removed
in LUA5.4 in favor of native language support of bitwise operations.
Yet, it's easier to backport this module rather than patching all the
existing LUA scripts because most of them can't be tested.
Streamlined legbrute to remove then need for CSN and validate variables accuracy as per Iceman's suggestions.
Updated legrec (client side only) for the future arm side PR
Fixed variable overflow on the arm side for hex conversions
This was done programmatically using python.
The `lf_Keri.pm3` was in range `[-508 .. 491]` (1000 value range).
Each value was divided by four, cast to integer, and then adjusted by +1 (to center the values).
The data plot in the pm3 client now shows discernible changes in amplitude.
The resulting samples are all within range [-128,127].
This final fix allows ALL sample `.pm3` traces to be converted to one-byte-per-sample binary format.
This was done programmatically using python.
Files with a range that fell outside of [-128,127], but which would fit into that range, were offset by the noted amount to ensure the file woul now fit within range [-128,127]. This allows the trace files to be converted to one-byte-per-sample binary format, for example.
offset | filename
-----|-----
`-14` | `lf_Q5_mod-manchester.pm3`
`-14` | `lf_Q5_mod-nrz.pm3`
`-10` | `lf_Q5_mod-fsk1.pm3`
`-15` | `lf_Q5_mod-biphase.pm3`
`-9` | `lf_Q5_mod-fsk2.pm3`
Update legbrute to perform a double check when finding a potentially valid raw key, to ensure that is indeed the raw key and works against multiple macs (for the same epurse values).
Updated legbrute to use an even number of threads and display the starting key of every key block. Useful in case the operation needs to be halted and resumed
