Hexadec:
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.
Unfortunately, to this day, I haven't been able to find anybody who can make a board that made for a WL-CSP footprint.
Its more of a massive company, large production kind of capability.
If anybody knows of some fabricator, throw it out.
Most places that can handle 4mil rules can do it, but I still have to cheat by altering the shape of the outer BGA pads. A couple of PCBAs have reviewed this and seem to think it will work fine; one even said it's approximately what they would have done to my Gerbers without my asking.
The code is not changed at all.
Okay, I didn't solder a pin to my RSTN hole. I'll see what I can do about getting one soldered on after some class tomorrow. I just tried to heat up my iron in my dorm and I smelled awful. Didn't want the alarm to go off.
Schematic...Lemme see...I can't find it right now, BUT! I know its right. I went over it about seven times. I always do a check like that before I send something to fab.
Lol, wow I feel dumb. turns out a few of my pins weren't soldered to the pad on the AS1130. Should look closer next time.
Good news is I have to go home to get my suit so I can solder those down. I'll report back when I have it soldered down
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!.
I am working on a project using AS1130 and have problem in making scrolling works. I would like to do scroll of 'digit' accords 5x48 LED using 2 AS1130. (Similar to page 32 of datasheet) . I can already display the 'digit' on the LED matrix, but when I start scrolling, the 'digits' just do not pass the CS11 boundary. Can anyone give me some direction? Thanks in advance.
Follow is the way I am using now:
as_config(0xc0, 0x0B, 0x02); //IC1 sync out
as2_config(0xc0, 0x0B, 0x01); //IC2 sync in
as_config(0xc0, 0x01, 0x40); //movie of frame0
as_config(0xc0, 0x02, 0x01); //play 1 frame
as_config(0xc0, 0x03, 0x31); //scroll digit in 5LED block
as_config(0xc0, 0x04, 0x2B); //CS0 to CS11
Whoa. Can you see out that while it is going? Add a mode when you can power blast. Be a superhero! Also, remake with RGB leds, you could be totally freaky. I love that. If that was your idea that is a great one.
