Update to xealousbrown. (#8215)
* Update to xealousbrown. 5-13ms Latency decrease, 4x scan rate improvement. (CUSTOM_MATRIX = lite) is a really great feature! * Updated Readme.md, added an extra speedhack. * More optimizations * Update keyboards/handwired/xealousbrown/rules.mk * Update keyboards/handwired/xealousbrown/rules.mkmaster

Make example for this keyboard (after setting up your build environment):
|
||||
|
||||
make handwired/xealous-brown:default

make handwired/xealousbrown:default
|
||||
|
||||
|
||||
The brief list of speedhacks to make this keyboard blazing fast:
|
||||
1) bit-bash implementation of scanning rows, columns. Very short delay between pin waiting.
|
||||
2) Compiling with a few extra flags
|
||||
3) Eager-per-key Debouncing algorithm (no 5ms delay before message is sent)
|
||||
4) 1000hz polling
