READme.txt says the following:
This is a basic port of MicroPython to the Parallax P2 Eval board.
To run it, load the upython.binary file into the P2 board. It will
talk on the standard serial line at 230400 baud. It will also try to
talk to a VGA board based at pin 48 and a USB keyboard based at pin 16
(using the standard P2 eval A/V and serial host expansion boards). The
USB driver used is garryj's excellent single COG keyboard/mouse driver
(although I haven't implemented mouse support yet).
How do I load the upython.binary file into the P2 board? Using a terminal program, like PST, or some other method? Are there any total-noob instructions out there?
