dropped it like its hot, dropped it like its hot.
On a better note, I am feverishly working on getting one mounted. 
I've never done such a tight pitch IC, last time one of the legs bent while soldering and I was so pissed.

Probably accidentally got it working right, and dropped this thread like a hot potato.

Guess so...the last thing he posted was that it was working how he wanted it using my code! then he disappeared.

No thank-you, kiss my arse or anything.... smiley-roll-blue

Makes you really want to help people doesn't it?  smiley-mr-green

Yea, last party was new years! That was a crazy night.
Its for a worldwide competition. 
I can probably find some time tomorrow after a speech.  I need to construct the circuit yet, I just have the AS1130 mounted.

I am very slowly designing a 4-layer board with some AS1130's. The biggest pain has been finding out that my usual cheap PCBAs don't want to do 0.5mm BGA/WLCSP.

Oh weird, I didn't notice that "binarygod" actually deleted everything. That's really antisocial.

Okay time for an honest question though. 

With the TLC5940, there is an ISET pin, where you basically put a resistor there and it would set the sink current for the leds (common anode rgb leds).

With the AS1130, I didn't see any current or voltage setting.  I don't want to burn out 132 red LEDs, do do I put the proper resistor before the CS lines?

Don't turn in to BG FFS.... smiley-mr-green smiley-mr-green smiley-mr-green

The CS register sets the current anywhere from 0 to 30mA (0-255)  smiley-razz

It's a shame they only do 1 package for this chip...it probably puts lots of designers off, not to mention hobbyists.
