[simpits-tech] Arduino, Part Deaux...

[raysot at comcast.net]

The (new) Arduino is up and running, spitting data out to both an LCD panel and also sending a 12-bit data stream using CS, CLK and DATA outputs. I have it cranked up pretty fast.. should be sending about 30 updates a second.. should be more than enough for smoothness.

Tonight I solder the CS4122 SOIC chip to a makeshift breadboard breakout card and start wiring things up.

I know what happened to my original Arduino... My breadboard power rails had (had) a ground, +5vdc and +12vdc rails. I was wiring up a switch, and the circuit called for a 1m pull-up resistor. I mistakenly plugged in a 100-ohm into the 12vdc rail.

Now I have the rails a bit more segregated and 12vdc is isolated to a single rail so it's out of the way and not as tempting.

Not having looked at the specs, I would recommend using the chip enable 
pin if one is present. That lets you keep common data & clock lines 
across multiple parts. If CE isn't set for the part in question, it'll 
ignore the clock & data lines.
