Description

CardKB is a unit that can implement a full-featured QWERTY keyboard. Consider that you want to make some cool stuff that requires keyboard typing and interaction, but M5 core itself just have 3 buttons, here comes the flexible and powerful CardKB unit.

It also can achieve button combination(Sym+Key, Shift+Key, Fn+Key) and output richer key value. This unit communicates with M5Core through GROVE A port(IIC interface). The address is 0x5F.

1. Button combination description:

  • Single-button pressed, the keyboard will output the first key-value(letter button will output lower case form). E.g if "Q" was pressed, the keyboard will output "q"(lower case).

  • Sym+key, the keyboard will output the second key value. E.g if "Sym" was single pressed, then "Q" was pressed, the keyboard will output "{". If "Sym" was double-clicked, then the keyboard will lock this function, all key pressed will output its second key value.

  • Shift+key, if a letter button was pressed, it'll output the upper case form. E.g if "Shift" was single pressed, then "Q" was pressed, the keyboard will output "Q". If "Shift" was double-clicked, then the keyboard will lock this function, all letter key pressed will output its upper case form.

  • Fn+key(custom function key combination), the keyboard will output the third key value. You can custom what function the key pressed corresponds.
