barometer of bliss


Since a barometer was on the manifest for VicaGlider & the credit card reset on May 1, decided to nuke it.

So far, the DRDY pins R not tristate. U need discrete microcontroller inputs for those in addition to the discrete outputs for the chip selects. Those chip selects need to be diode/resistor converters so they default to high.

We have the barometer & mag sharing the same SPI bus, but the barometer updates far less frequently than the mag. U have to send some commands to the barometer, wait 0.5 seconds for it to send an interrupt, get byte #1, send more commands, wait, get byte #2, & so on. Getting around that problem is going to put this story out of commission for a while.

Oh and yes. Figured out why Maker Faireeeee looked so washed out. Been raising the black levels because everything looks too dark on the HP.
