Anyone.... This query pertains to the reconfig of the SPI on the HB done with a poke(0x1009, 0x3c) which turns the MISO, MOSI, SCK and SS into digital outputs. My question is: "What is the reverse poke if I wanted to turn the SPI back from digital (...) (28 years ago, 27-Mar-97, to lugnet.robotics.handyboard)
