Message-ID: <1211924935.3518360.1451362224733.JavaMail.yahoo@mail.yahoo.com> (raw)

A few months ago I brought up the question of small
platforms suitable for a course on small/embedded
computing. If you recall the conversation, with input
from the collective wisdom, I decided to use the Pi.
At that time several people asked if I could share
any results from the course that I'm able to. I've
finally finished putting some of it together in a form
that's useful. In
/n/sources/contrib/blstuart/pi/ ...
http://cs.drexel.edu/~bls96/plan9/pi/ ...
are a collection of changes with all the changes
collected into a tarball:
/n/sources/contrib/blstuart/pi.tgz
http://cs.drexel.edu/~bls96/plan9/pi.tgz
The changes include:
- Richard's post 9pi.img changes on contrib
- I2C and SPI contributions from Steve Simon with the
I2C support ported from Inferno
- Enhancements for I2C and SPI
- Devgpio driver
- Man pages for I2C, SPI, and GPIO
- Support for a 320x480 SPI TFT display
- Enhancements to the USB keyboard support to handle
the Rii k12 keyboard/trackpad combination
I've also posted a little video (apologies in advance for
the quality, or lack thereof) of a Pi with the TFT screen
and k12 keyboard controlling a PiBog vehicle my wife
gave me for Christmas:

I'll look into making the slides I used in the lecture
available if there's interest.
There are some rough edges, but hopefully it might be
useful to some.
