Is it possible to interface a matix keypad (2*3) to a CC2430 ? If yes, to which ports ? How can I select pullup resistances ? Should I straight away go with 10k resistance. :?:

i have not used CC2430 but i had checked its datasheet.

general purpose ports are avialable. so,you can use it for this matrix keyboard.
pull up resistor will be according to input. please refer the datasheet for that.

according to me if any port from MCU is free then we can use it.
we have to check its output status for pullup resistors from datasheet or its features..

please read the datasheet carefully.
