Pad driver - read input from MD controller
|
||
|
|
|
||
|
|
Conveniently expose an API to read the status of a MD pad A.
|
||
|
|
Moreover, implement a mechanism to input arbitrary characters
|
||
|
|
from it. It goes as follow:
|
||
|
|
|
||
|
|
* Direction pad select characters. Up/Down move by one,
|
||
|
|
Left/Right move by 5
|
||
|
|
* Start acts like Return
|
||
|
|
* A acts like Backspace
|
||
|
|
* B changes "character class": lowercase, uppercase, numbers,
|
||
|
|
special chars. The space character is the first among special
|
||
|
|
chars.
|
||
|
|
* C confirms letter selection
|
||
