I really didn't have anything in mind other than the solution.
How could you use the SPI port to communicate with the PIC?

| (...) Well, in that case, the SPI port is what you want, provided an SPI port is also available on the PIC. Then just set up the SPI config, load the register and the computers exchange 16 bits shifted on a clock generated automatically by the (...) (28 years ago, 9-Jan-97, to lugnet.robotics.handyboard)
