AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver

You can choose them with the multiplexers...yes...but what addresses will you use for the I2C writes?

No problem...I just want to see if you know what the addresses will be when you set your jumpers. :wink:

Incrementing the addresses won't work.... :smiley:

there are only three lines I don't understand...can I ask that question...?

:grin:
ask away...

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. :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.

WTF :fearful:

Where's he gone??

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

...or...hexagod.... ]:smiley:

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

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

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.... :roll_eyes:

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

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

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.

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

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.

PCBA?

Short for PCB and Assembly shop.

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?
