Rewrite the Bathroom Epiphanies Frosty Flake matrix and LED handling (#8243)
* Keyboard: revamp frosty-flake leds This commit transitions bpiphany/frosty_flake to led_update_{kb,user} and rewrites the AVR bit twiddling logic to use the standard QMK GPIO API. * Keyboard: rewrite frosty_flake's matrix reader to be a lite custom matrix This commit replaces frosty_flake's custom matrix and debounce logic with a "lite" custom matrix. In addition to being somewhat clearer, this allows a consumer of the flake board to choose their own debouncing algorithm. The one closest to the implementation originally in use is sym_g, but this opens us up to supporting eager_pk and eager_pr. The original matrix code was 18 columns for 8 rows, but using a single row read and unpacking the bits into individual columns. To simplify, I've changed the key layout to be 8C 18R instead of 18C 8R: this lets us use a single read directly into the matrix _and_ drop down to a uint8_t instead of a uint32_t for matrix_row_t. Since we're no longer implementing our own debouncing and row unpacking, we save ~400 bytes on the final firmware image. Fully tested against a CM Storm QFR hosting the flake -- this commit message was written using the new matrix code. Firmware Sizes (assuming stock configuration as of 42d6270f2) Matrix+Debounce Size (bytes) --------------- ------------ original 17740 new + sym_g 17284 new + eager_pr 18106 new + eager_pk 18204 I expect that there are some scanning speed benefits as well. * Keyboard: update frosty_flake's UNUSED_PINS * Keyboard: Remove meaningless weak redefinitions from frosty These are not necessary (and all of them already live somewhere in Quantum).
