* initial clueboard_60 support * LED lighting support * fix the clueboard->clueboard_66 rename * Add layout support to clueboard_60 * Fix the 60_iso layout so it's actually iso * add a default keymap for AEK layout * fix clueboard_17 * Fixup the ISO layouts * Fix the `wait_ms()/wait_us()` definitions for chibios * Fix up the wait_ms/wait_us hack. Reduce stack size. * Add a missing #include "wait.h" * commit files that should have already been comitted
