i had previously recommended a screw terminal breakout board for making your own shagmatic board. the link follows. i recently discovered that for some reason. what would be pin 2 when using it with a teensy (marked appropriately as gnd on the board) is in fact connected to the ground plane. this renders that pin useless. the stock shagmatic firmware uses this pin for one of the config switches that sets a scaling factor for the joystick encoder. since this pin is tied to ground it will never work as an input pin. the solution is to either change to another pin and forget about using pin 2 or better yet, cut the little traces around pin two that connect it to the ground plane.
