OK I have just wired up the example schematics and tried out the example code from the Max72xx library using the Austria Microsystems AS chip and indeed it works perfectly without any modification at all.
More From This Seller: Yeah I’ve used these before – http: All you need to do is solder the header pins and soldder your own LED Matrix to the board. We thought you’d like these too… Sale.
I guess it should be. Make sure you use a LED Matrix you use is common cathode. Join our mailing list and stay updated about pioneering hardware and Tindie community activities.
Follow us on twitter friedcircuits. The current 33k Ohm resistor allows you run from USB power. I was just about to post my results. The seller may be offering an improved version or it may be hanging out on the beach, enjoying the retired life. All this and there is a ready-made Arduino library for this IC.

Hi, the AS from austriamicrosystems is 1: Is the LedControl library compatible with them?
View Options and Buy. All documentation will be available at http: A code example for scrolling text will be available on the website. Give it a try and let us know how you get on. Also the more modules affect performance. This is where MobileWill has documented our adventures in electronics over the years.
I ordered 10 from Newark. It is indeed compatible with the Max7xx libraries available.

Based on my quick look at the sheet and the library code, it seems like it should probably work, but may not support the added ‘features’ code. We’ll see in a week or so when I get the parts. As you say, these chips are obviously a direct replacement for the Max72xx chips but with the advantage that they are: AS unfortunately you have to invert the input vs.
I too have a bunch of 8×8 matrixes lying around that I’m itching to get working You beat me to it! Will do, I have 3 free samples on the way from Vienna Austria that should arrive in two days.
I was actually able to do all 8 but it reduced the brightness a tad.
Log in with Facebook. It has been done before and the Arduino forums should be helpful if this is what you are looking to do. The AS does this in addition to adding SPI control, daisy chaining capability, and le resistor brightness control.
