    I am trying to light a bunch of LEDs, and am considering using a shift register (there are about 60 outputs to LEDs in this particular device, so even a MEGA falls short).

    Every example I see uses Arduino's Pin10 for the clock (SS) and of course it is a conflict with the radio, which uses Pin 10.

    SPI library relies on Pin 10...

    Any suggestions on how to to accomplish getting my shift register working on another pin? Is there a software solution?

    thanks.

      @BulldogLowell shit register can be easily been driven by software SPI
      just google for software SPI of software diver for shift rgister

      sense and drive

        I searched and searched before I posted the question and it turns out, it is in the arduino IDE already.

        shiftOut()

        thanks
