Ben V. Brown 347968e4ef 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
