Has anyone interfaced the HB to a PIC chip or other microcontroller without using the primary serial lines? I am wondering if maybe there was an I2C or SPI implementation done somewhere using digital outs. (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)

Hello, I am a beginner in Robotics and have looked at the Handy Board, Miniboard, BotBoard, and Basic stamps. I have decided I think I like the HB. The only thing is I want to make a mobile robot or arm that has basic AI, maybe using Subsumption. I (...) (28 years ago, 8-Jan-97, to lugnet.robotics.handyboard)
