Songguo PTS200

This branch is forked from the official firmware of the PTS-200 soldering iron. I fixed some bugs in it, and also modified this and that, I didn't like.

• Bugfix: Eddddddddy#19
• Bugfix: Eddddddddy#13
• Always show measured temp, even at startup. Never show "000" as temp, which can be dangerous
• I modified the large fonts on the two main screens, as I didn't like the original ones
• Totally modified the "Big number" screen: Set temp in the top-left, input voltage in the top-right, status is shown by different icons
• Adjusted temp calculation. Now it is much closer to the measured real temp, with TS-100 tips
• Adjusting temp on the main screen is temporary. It won't save as Default temp

Introduction

1. PD3.0 and QC3 fast charge protocol

2. 20V 5A 100W maximum power

3. Built-in IMU for sleep detection

4. PD protocol chip uses CH224K

5. MOSFET supports 30V 12A

6. MCU uses ESP32 S2 FH4

7. The power input uses a power-enhanced USB-C interface

8. Customized soldering tip with 4 ohm internal resistance. It can be powered by 20V with 100W.

9. 128x64 OLED screen

10. 3 buttons, the middle button is connected to GPIO0

11. MSC firmware upgrade, flash disk mode

12. With a portable tip cap

Build method

1. Arduino with ESP32 environment

2. Install dependent libraries: Button2, U8g2, QC3Control, ESP32AnalogRead, PID_v1, SparkFun_LIS2DH12

3. Replace the u8g2_fonts.c file from the U8G2 library

4. In Arduino, select Tools-USB CDC On Boot-Enable

5. In Arduino, select Tools-Upload Mode-Internal USB

6. Click Upload
