Otter-Iron - TS100 USB-PD hardware mod

With this release your TS100 will remember it's set-point, won't overshoot anymore, shows a better DFU-screen and get a nice power-showing-bar! Temperature control is now much more advanced... Much less crappy at least. :3

Firmware Download: https://github.com/Jan--Henrik/Otter-Iron/releases/tag/v0.3

I just released firmware v0.2:

This release adds a dfu-bootloader (to enter press both buttons while plugging in, display will show "dfu") and a cascade controller (Two-step controller + PID, faster heating and less overshoot). Firmware is still shitty af ^^

dfu-utils usage:

dfu-util -a 0 -s 0x08000000:leave -D firmware.bin
