Restore default keymap

Set the key with the key code of 0x7C03, and then press it.
Then a reset will restore the default keymap.
See #8.

Restore default keymap (tinygo flash)

Restore default keymap each time it is reset by specifying --tags reset_to_default.
Note that in this setting, any changes made from Vial or other sources will immediately revert to the original setting.

$ tinygo flash --target wioterminal --size short  --tags reset_to_default ./targets/wiokey

Note

• Basically, the --stack-size 8kb settings is required.
• If changing the version of tinygo-keyboard causes it to not work properly, please perform the Restore default keymap procedure.
