Basically, $10 for an AVR processor, $15 for a programmer, $10 for a breadboard and some odd bits, then learn a bit of C, steal some free bits of code off the Internet, and now I have an EMC2 compatible fast PWM generator and a lot more that I just haven't figured out yet (...priceless). It's not nearly as fast as an FPGA, but maybe fast enough. By the way, I got the ATmega32 version working, so I have eight bits of input now, plus a bunch of pins left over. Four PWM channels are advertised but they aren't fully independent of each other and share pins with other features, so the plot thickens. I have an LED on the PWM output (sinking) and it stays on a tiny bit at 0, so I may need to look into this too.
