Member Function Documentation
| bool KeymapManager::handleHidModifier | ( | uint8_t | keyCode, |
| bool | bDown | ||
| ) |
If the given keycode is a modifier, applies it and returns true, otherwise it returns false.

Here is the caller graph for this function:
| uint64_t KeymapManager::resolveHidKeycode | ( | uint8_t | keyCode | ) |
Resolves a HID keycode using the current keymap and returns a "real" character in UTF-32 format, plus modifier flags in the top 32-bits.
