[solved] keypad.h data type

-

hi!

i want use keypad library sending midi messages.
so instead if having characters mapped buttons need have numbers 0 127. problem don't know how change data type (char) integer or byte.

i map keypad char , use switch/case ugly because consumes more processing power.

anyone have idea how this?

code: [select]

char key = 'a';
byte num ;

num = (byte) key;

it called casting variable.

to map key number use array.
