Fillout settings functions
Settings menu works Movement working & TMP calibrated Tip reading sensibily Accuracy seems ok Trimmed down overshoot by biasing integral Saving to flash working, detailed idle Sleep mode Description scrolls Building for DFU working Motion detection update Use manual alg instead, using highpass filter, then sum current change vs rolling average Re-shuffle the pwm code organisation
