2020-09-08EEPROMLeonard Kugis-28/+158
State machine finished. EEPROM io working.
2020-09-05SoftwareLeonard Kugis-27/+185
General mechanism working. Needs refinement with EEPROM store/load.
2020-09-04Input, HandlerLeonard Kugis-86/+281
Reworked display function. Input fully working. Implemented basic entry handler.
2020-09-03InputLeonard Kugis-22/+518
Moved old state to test.
2020-09-03InputLeonard Kugis-24/+24
Readout bits not negated. Manual clearing of input shift register.
2020-09-02InputLeonard Kugis-77/+103
Input now working. Still buggy. Presses remain unstable. Needs either buffer capacitors, readout redundancy in software or both.
