7.3 Keycode
The section above introduces keymap definition in app_config.h and keycode filling in
KB_MAP_NORMAL. To realize standard USB HID keyboard, some special keycodes
need to be processed, so user should pay attention to details for keycode definition.
The “kb_remap_key_row” function in keyboard.c serves to process keycode.
void kb_remap_key_row(int drv_ind, u32 m, int key_max, kb_data_t
*kb_data)
Figure 7-2 Keycode Processing Function
CTRL KEY will be obtained by kb_event.ctrl_key, and its keycode ranges from 0xe0 to
0xe7 which cannot be used by users.
