Change Details

labsw/LOG
221221  - added external pull-ups to IN_* and to buttons (so that we can turn
222222    off the internal pull-ups and thus avoid sneak current through the
223223    opto-coupler LEDs from VBUS via the pull-ups into VDD)
224  - added low-pass filters to button inputs, to suppress interferences,
225    e.g., from load being switched (with help from Joerg Reisenweber)
224226
225227Pending:
226228- widen column cavities by 0.2 mm on each side
