The pdf file in this folder contains an analysis of datalogs of the programming sequence of a PMS150C and PFS154. The data was recorded by Frank Buss on a fast analog sampler he built for that purpose. The original data can be found here and here.
The purpose of this analysis is to allow a clean-room implemention of the Padauk programming protocol based on behavioral analysis, without having to revert to software reverse engineering.
Another, prior, analysis of the PFS154 protocol by js_12345678_55aa, socram and others can be found here and following.
