The basic command to set a pin mode is + + palSetPadMode(TEENSY_PINn_IOPORT, TEENSY_PINn, PAL_MODE_INPUT_PULLUP); + +The last parameter is the mode. For keyboards, the usual ones that are used are `PAL_MODE_INPUT_PULLUP` (input with a pullup), `PAL_MODE_INPUT_PULLDOWN` (input with a pulldown), `PAL_MODE_INPUT` (input floating, a.k.a.
