    bit banging spi, dont think im getting anywhere

    hopefully this is a good sign but i finally got the data for one command i was expecting to see. hippy i put a 10k pulldown on the miso line and cleared up the noise and then moved my chip select commands to the main portion of the code as you suggested with them before the shiftout gosub and...
