Looks good! I will have to get set up for doing PCB's again. I'll probably use the toner transfer method. My mill "sort of" work, but I don't trust it yet.
It might be a good idea to make provisions for a crystal, just in case 8Mhz is not fast enough. The avr program chops the power at about 20khz, so it only have about 50 uS to run. Also, chopping produced a lot of electrical noise on my system. It acted very irratically until I put a .1u on the step pin.
I will post my code as soon as I test it a bit more. |
