Songguo PTS200

PTS-200 soldering iron firmware, forked from Eddddddddy/Songguo-PTS200. With some bugfixes and customization.

• Bugfix: Eddddddddy/Songguo-PTS200#19
• Bugfix: Eddddddddy/Songguo-PTS200#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
