Compatibility for new displays - if you upgrade you will be asked if
the screen shows blue or red.
Improved the temperature measurement, the 100k pulldown altered the
measurement, so the temperature was 30-50°C hotter than measured.
Based on this measurement error, you can now officially set the max
temperature of 450°C.
Removed misleading offset temperature, if colder than 50°C it only
shows cold.
Added direct heating on boot and option to disable this and auto
shutdown. Just press the power button when booting (led blinking).
Powering the tip will no longer heat to standby, even if it was in
standby before.
Added installation routine, do not use if you don’t know what you’re
doin’. Intended for external voltage divider (temperature element fake)
and LED attached to heater instead of using a weller tip.
Reduced prescaler to 128 for less noise. Testing is needed to reduce it
further to something between 1 and 32 to eliminate sound from switching.
