/diy/ - Do It Yourself

Shit, now that's the second time in a few days it's fucked my SD card so I have to reformat it, as I think the crash is happening inside the SD-card reading function. Any earlier and there isn't anything fancy to crash, anything later and CTS would be pulled high again and I don't see that.
I'm going to check out SDfat once my card finishes reformatting. Anyone know if the Adafruit fork is the one to go for? The non-Adafruit one was updated more recently, so I'll go for it first.

Guess where the LED goes? Yep, from D13 to GND with a resistor. Who'd a guessed? So it always has a ~1k pulldown, meaning you'd need an even smaller valued resistor as a pullup to counteract it, so small that you'd set the resistor on fire. You'd be better off having a button to Vcc instead. I always have both the pinout and schematic on hand so I know what I'm dealing with. That one you posted isn't too good for knowing which pins are PWM and which aren't, I prefer this one. Pins D11 to D13 are also behind the ICSP header, so I tend to avoid them as they could mess with programming it later.
