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.

HEYOOHHHHH figured it out! I have a mounted as1130.
Now its time to find time to test it out

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:

Come on Funky man...let's see some action on your project.  :smiley-mr-green:

You'll see some soon! I have a very pressing project that is due in exactly........................68 days!  An entire website!  So I just literally stayed up all night, in fact I think I see a little sunlight brightening up the night sky out there.

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.

Why would he go to all that trouble?
I mean its not like he can pass off never having had gotten help from us.  Hexadec has private messages from him, lol.

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)  :P

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