Firmware for Feizer PTS200 soldering iron.
I've started this project as a fork of Songguo PTS200 to completely rework original firmware. My goals is to create a well-structured firmware with a flexible design.
Currently project is in it's early development stage. Additional features and UI redesign will follow.

QC trigger is an experimental feature. Since QC trigger uses same lines as USB data, those function co-exist pretty bad together. Due to lack of design schematics and documentaion it is not easy to implement it properly. When QC is activated no other USB operation is possible, including firmware download! It also affects system message output to Serial
line which migh result in UI slownes or freezes.
[!NOTE] Do not activate QC-trigger on permanent basis! Do this only when no other PD sources are available and you need to work with USB Type-A powerbanks, or PSUs. Disable it when not needed in configuration menu. On each QC mode change it is required to unplug/replug the Iron!
Use PlatformIO to build the project.
Attach the iron to USB port and run pio run -t upload
in project's directory. See Update Guide for details.
