attiny26 and Usbtiny

[foxah]

Does the usbtiny program the attiny26, or is the chip too old to be supported?

I am using avrdude, with OSX

Thanks,
-Adam

[adafruit]

yes it does

[foxah]

I cannot get the usbtiny to talk to my attiny26. Any ideas about common mistakes I might be making?

OSX, avrdude

Thanks,
Adam

99% of the time, this means your programmer is fine and you have a wiring problem w.r.t the target chip
