Hey...you should try to market that idea...it might catch on... smiley-mr-green

I had a similar problem with one of my chips on the 528 LED board, it was intermittently working and after a lot of messing about I found 1 pin was not soldered properly!.

Remember it for the future (like I didn't)  smiley-mr-green

Thanks for the link Mr Force...good to know for future reference.

Sorry about the delay...been away for a few days.... smiley-cool

The RSTN pin needs to be pulled to logic 1 or the chip will keep resetting.

The IRQ pin has no effect whatsoever if you're using the PWM example code. (It's not used).

Are you using the code "as is" or modified?

Also let's see your hardware/schematic... smiley-wink

It's a shame they only do 1 package for this chip...it probably puts lots of designers off, not to mention hobbyists.
Well you can also get the Ssop-28 package which is available too.
that will solve your problem with soldering. The package was available shortly after the wlp.

OOps...yep forgot about that... smiley-red smiley-red

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.

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

Students never change...party 'til the last minute...then PANIC!  smiley-mr-green smiley-mr-green

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

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

lol, I have no idea.  maybe transistorgod got him.

WTF  smiley-eek-blue

Where's he gone??

why not? you did that in your code you sent me and why that doesn't work?!

You called yourself binarygod....you tell me why it won't work.  smiley-wink

in the function 'load_data' you wrote these three lines:

IC_SEND(i);
IC_SEND(0);
IC_SEND(0);

That doesn't look like any code I have ever written...neither for the Arduino nor the PIC.

Incrementing the addresses won't work.... smiley-grin

there are only three lines I don't understand...can I ask that question...?
smiley-mr-green
ask away...

This is starting to look like my threads.... smiley-mr-green
