Version 1.4.2 of the IECHost command-line nibbling utilities is now available within my Software page. Binaries are available for Windows, macOS (Intel), Linux x86_64 and armv7l.
This is the first publicly available release of the nibbling utilities, which require the use of the extended IECHost firmware that ships with them, instead of the standard IECHost firmware. The former is backward compatible with the latter, but I recommend not mixing things: use the standard IECHost firmware when running non-nibbling software and the extended IECHost firmware when running nibbling software. Best even, have two IECHost devices: one for non-nibbling purposes and one for nibbling purposes, so you can reduce the overhead of switching between different firmware versions.
