Are you referring to using the SPI port on the Handyboard, or simulating
the SPI function via other ports? If you run the handyboard as a master,
then the handyboard is responsible for providing the clock output used to
capture the data by the slave, and you don't have to worry about speed, so
you could bit-bang it out another port via IC statements. However the SPI
is unused and easy to set up.

| 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)
