Some ideas, before I forget them

Commit by micah :: r6024 rfaccel/ (calibrate-test.py calibrate.py):

Implement the statistical calibration, and add a cute little 3D-ish demo using rtgraph's isometric widget

Commit by micah :: r6023 rfaccel/ (7 files):

Do a bunch of refactoring, and start some calibration. This current attempt uses a generic optimizer to minimize an error function that rewards acceleration magnitudes close to a supplied constant for gravity. Unfortunately, the optimizer has decided that very small gains and biases at an arbitrary point on a sphere with radius g work just fine. Blah.

Woo, rtgraph!

Commit by micah :: r6020 rfaccel/firmware/ (Makefile pista.conf rfaccel-tx.asm tx/):

Take firmware out of the 'tx' directory, since we won't need receiver firmware

Commit by micah :: r6019 rfaccel/ (firmware/tx/rfaccel-tx.asm test.py):

Woo, I think the RF bits are working. Instead of a custom receiver, this is using normal RS-232 now. Included a small python program to receive and validate packets.

Commit by micah :: r6018 rfaccel/ (6 files in 3 dirs):

First whack at some firmware for a wireless 3-axis accelerometer. The protocol will probably change to something I can receive using a standard RS-232 port, since right now i'm too lazy to make a fancy receiver.
