I just fixed the reset problem the AKOI2C has had ever since its beginning. It turned out to be an uninitialized state variable. On a POR, the register file gets cleared with 0's. But on an MCLR reset, the user registers in the register file are untouched. The uninitailized variable caused the AKOI2C to sometimes reset into an indeterminant state, which would cause the chip to lock up and quit responding. I'm annoyed it took me this long to find it.

AKOI2C
Got the AKOI2C firmware, device drivers, schematics, and board layout into CVS over at SourceForge. Also released an AKOI2C tarball with the stuff in it. Go to http://ako.sourceforge.net/akoi2c.html to see it.

Nathan Brown's R'n'B
Played a strange show out in Denton last night (I play violin in a band called "Nathan Brown's R'n'B"). We showed up at Rubber Gloves in Denton, and they told us we were going on second. So we left to go get something to eat. We got back about 10:10 or so and the first band was setting up on stage. At about 10:35, they tell us we're going on first, and the other band has taken their stuff off the stage. So we tried to setup really fast, but it still took us untio 10:50 to get ready. The sound guy comes out and tells us we can play until 11:05, which doesn't make any sense because the delay is their fault. We play three songs, and then they tell us we have time for a "quick" song. So we played the longest song in our set. ^_^ We only got to play half the set, which is a shame because it was sounding really good. It was the first performance I had used my new effects processor, and the violin sounded really nice.

Finally got a web page up for Project AKO over at SourceForge, with lot's of pictures. No source code yet, though. It's going to take another day or so to get that in order to put up there.
