* initial commit, added opt3001 light meter test app * tested working light meter board, i2c communication still has issues * fixed i2c; rudimentary lightmeter works! * added aperture priority ui * added aperture priority ui * added README * adjusted cal * fixed bugs (HI shutter speed, lux mode toggle) * made it possible to advance to the next face * initialized lux variable * lowered tolerance for HI and LO * Changed EV display from always showing EV100 to showing EV[iso setting] * dont display old ev when ISO changes * changed mode and light behavior * updated readme * fixed indentation * made lightmeter display logic more consistent * made lightmeter display logic more consistent * reverted rules.mk (for merge into upstream) * reverted rules.mk (for merge into upstream) * removed OPT3001 PCB model * made lux mode default, corrected timeout behavior --------- Co-authored-by: Christian Chapman <user@debian>
