...Xenome is kind of a cool name. And I'm not doing anything even a little bit like genetic research. Well maybe a little bit. I dunno.
Anyhoo, things have been a little quiet on this blog but certainly not in the analog, er, real world.
I solved that problem with the strip values bleeding over onto eachother by adding a 10k resistor between signal and ground on each input. Pow, zap, fixed. Now I can bloop each channel seperately. Yay!
Then I went back to work on the led driver board, the one that's going to hold 16 MAX7221s and run my 112 led graphs. I'll link to the circuit board layout once I get the proto back from the manufacturer and make sure it works. I made some last-minute changes late at night right before I hit "order" and I'm hoping I didn't kill anything. I added a 20 pin header and ran the SPI interface to one half and power and voltages to the other. Kind of bad practice but I happen to have a box of 20-pin headers and sockets and ribbon cable so why get fancy. I can always skip the header and solder right to the original pads (which I left in place). So the boards should be here late next week.
