Dynamic macro functionality is modified to check for `DYN_REC_STOP`, so
that macro recording can be stopped with a designated key combination
(e.g. `qs` or anything) instead of mandating the use of a `_DYN` layer.
`_DYN` layer stopping can still be done by passing `DYN_REC_STOP` within
`process_record_user()`:
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
uint16_t macro_kc = (keycode == MO(_DYN) ? DYN_REC_STOP : keycode);
if (!process_record_dynamic_macro(macro_kc, record)) {
return false;
}
return true;
}
Empirically, waiting for N consecutive identical scans as a debouncing
strategy doesn't work very well for the ErgoDox EZ where scans are very
slow compared to most keyboards. Instead, debounce the signals by
eagerly reporting a change as soon as one scan observes it, but then
ignoring further changes from that key for the next N scans.
This is implemented by keeping an extra matrix of uint8 countdowns, such
that only keys whose countdown is currently zero are eligible to change.
When we do observe a change, we bump that key's countdown to DEBOUNCE.
During each scan, every nonzero countdown is decremented.
With this approach to debouncing, much higher debounce constants are
tolerable, because latency does not increase with the constant, and
debounce countdowns on one key do not interfere with events on other
keys. The only negative effect of increasing the constant is that the
minimum duration of a keypress increases. Perhaps I'm just extremely
unlucky w.r.t. key switch quality, but I saw occasional bounces even
with DEBOUNCE=10; with 15, I've seen none so far. That's around 47ms,
which seems like an absolutely insane amount of time for a key to be
bouncy, but at least it works.
Using only one layer, and activating it with two keys at the moment.
As with previous comments, this isn't final, but is a good starting point for a one-handed keyboard, half a Planck-like ortholinear keyboard, or a sample to show a layout with a function layer.
There was a typo, so the attempted configuration proably didn't do
what it should have done. I think it left the pin floating, and
could cause the LCD problems issue-1230.
