Group' object has no attribute 'resultcallback'

[git-madresc]

Got a "AttributeError: 'Group' object has no attribute 'resultcallback'. Did you mean: 'result_callback'?" on a Python 3.11.2 (Raspian Bookworm).
Changing line 304 as suggested fixed this.

This is fixed by PR #11.
Unfortunately Adam seems to no longer maintain this code.

To make this and other fixes available I created a fork https://github.com/schwabix-1311/tc420 to add all new stuff there.
My fork includes all PRs found here, namely

• update to package click >= 8.1.0 => rename of resultcallback to result_callback
• non-sudo use of tc420
• USBTimeoutErrors
• multiple TC420 controllers connected to same system
