Utilize current measurement for "no-tip-detection"

The board is equipped with a current shunt. The voltage over the shunt is amplified with the on-board OP-amp and measured with the STM32 ADC.
By measuring the current it should be possible to detect if a tip is missing and/or broken. This requires some clever timing and measurement during the high-phase of the PWM.
At the moment the actual temp shows ~567 deg C when no tip is attached. It would be nice if AxxSolder detected a "no-tip" status.
