need help with NES gamepad controller program

I am trying to program the Basic stamp 2 to use a NES gamepad controller to control two continuous rotation servos with the D-pad and light an led with the A button. Does anyone know what program codes are needed to make this work? I would appreciate any help that i can get.

There is sample code for the BASIC Stamp and the NES controller listed on the NES product page. Here is a link:

You can use the values to activate the servos by setting up subroutines.

i have already used that program. the problem is that i can not figure out how to write a program to be conditional based on the binary input provided by the nes controller. i know which bit is for each button but i can not figure out the synthax that i need to write the program.

What are you trying to do exactly?

i am trying to use the d-pad on the controller to control two servos to give me two axis of movement. the up and down buttons will control one servo and hte left and right buttons will control the other. then the A button controls a single led light.

I am having this same problem. It's because the value from shiftin is not originally in bin or dec format. You only see it as bin in the debug terminal. So you need a command line that converts the value variable to BIN or DEC, which i can not figure out.
