# ESPIron PTS200

Firmware for [Feizer PTS200](https://www.aliexpress.com/store/1102411999) soldering iron.

I've started this project as a fork of [Songguo PTS200](https://github.com/Eddddddddy/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.

WIP:

 - decomposite project into independent tasks and RTOS threads

 - revised temperture probes scheduling

 - exclude useless tight loops

 - removed ALL blocking code, wiped arduino's `loop()` hooks, now all code is asynchronous

 - rework UI into non-blocking event based configuration system

 - Move configuration data to NVS key/value storage

 - Reimplemented temperature and timers configuration

 - use full-range PWM for heater

 - enabled PID control for PWM (not optimized yet)

### Key controls

| Idle/Working | `middle` | long press | Enter configuration menu |

| Working | `+`/`-` | single click | inc/decr working temperature in one step |

| Working | `+`/`-` | double click | inc/decr working temperature in 4 steps |

| Working | `+`/`-` | triple click | inc/decr working temperature in 6 steps |

| Menu navigation | `middle` | short press | enter menu section, comfirm action |

| Menu navigation | `middle` | long press | escape action, previous page, etc |

| Menu navigation | `+`/`-` | single click | move along menu items, inc/decr action  |

### Features

## QC Trigger

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!

## Build method

Use [PlatformIO](https://platformio.org/) to build the project.

Attach the iron to USB port and run `pio run -t upload` in project's directory. See [Update Guide](/docs/update_guide.md) for details.

## HW Details

#### Schematics

Iron [Schematics](/docs/PTS200_Schematic_2022-07-10.pdf) (probably from similar iron, some items does not match with PTS-200 v2)

#### Disassembly
