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

I'm allowed to have it 'cos it's not sharp.

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.


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