@ -221,6 +221,8 @@ To do: debounce buttons (in software) before accepting a state change.
|
||||
- added external pull-ups to IN_* and to buttons (so that we can turn
|
||||
off the internal pull-ups and thus avoid sneak current through the
|
||||
opto-coupler LEDs from VBUS via the pull-ups into VDD)
|
||||
- added low-pass filters to button inputs, to suppress interferences,
|
||||
e.g., from load being switched (with help from Joerg Reisenweber)
|
||||
|
||||
Pending:
|
||||
- widen column cavities by 0.2 mm on each side
