had trouble using the Dc-Dc convertor, it worked fine for simple LED blinking, but the IR detector would not work with that supply, even with filtering caps thrown in. O suppose there was too much ripples. It only started working when power was supplied from the TI Launchpad, or from the 4931 hooked up to provide 3.3V from the 9V battery.

pins are output GND Vcc
when placed with pins facing downward, and looking at lens
output connected through 220ohm resistor to digital in.

L4931
using m430G2553 ouside of launchpad:
------------------------------------
- add a 0.1uF capacitor (markd 104) between Vcc and GND as close to the chip as possible.
- tie the RST pin to Vcc through a 47k resistor. (schematic also showed RST being tied to
GND through a 1nF or 10nF capacitor)
