Usually the keyboard waits for the host to wake it up before any tasks are performed. This is useful for split keyboards as one half will not get a wakeup call but must send commands to the master. +* `LINK_TIME_OPTIMIZATION_ENABLE` + = Enables Link Time Optimization (`LTO`) when compiling the keyboard. This makes the process take longer, but can significantly reduce the compiled size (and since the firmware is small, the added time is not noticable). However, this will automatically disable the old Macros and Functions features automatically, as these break when `LTO` is enabled. It does this by automatically defining `NO_ACTION_MACRO` and `NO_ACTION_FUNCTION` ## USB Endpoint Limitations |
