Multi-phase, bi-color LED control

JonnyMac

I really like using bi-color LEDs; they're cheap and with a little code can provide a lot of information to the product user.· In the past I had written code that allowed a simple bi-color (2- or 3-lead) LED·to be a solid color or flash between two colors, and even have the ability to fade.· I found I never used the fading feature and wanted more phases so I've created this version of the object to do just that.

This version (jm_bicolor_v4.spin) allows me to control the LED using 1 to 4 phases, with each phase having a color setting (off, red, green, yellow) and duration (1ms to 1min).· The duration only matters when using 2 to 4 phases, of course; this sets the blink characteristics.· The object does allow you to control the yellow color mix with a constant, or to pass it (you specify the percentage of red) using the initx() method.

Everything seems to work just fine, but I'm going to wring this out for a couple more days before posting in ObEx.

Whoops... while making the code "prettier" I introduced a copy-paste error in the set4phase() method -- that's fixed now.

The 3-lead version that I tend to use is: 78-TLUV5300. I have some 2-lead units, but don't know where I got them so I don't have a part #.

Here's a 2-lead version on mouser. It's on B/O now, though.
