AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver

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.

[funkyguy4000]

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

[Hexadec]

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....

Makes you really want to help people doesn't it? 

[Hexadec]

Come on Funky man...let's see some action on your project. 

[funkyguy4000]

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.

[Hexadec]

Students never change...party 'til the last minute...then PANIC! 

[funkyguy4000]

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.

[funkyguy4000]

PCBA?

[macegr]

Short for PCB and Assembly shop.

[macegr]

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

[funkyguy4000]

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.

[funkyguy4000]

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?

[Hexadec]

Don't turn in to BG FFS....

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

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