Bus Pirate Support / Re: i want to program the paperduino with bus pirate
Code: [Select]
avrdude -c buspirate -P /dev/tty.usbserial-BPv3.6 -p m328p -v
You can also load up special firmware that makes the BP act like an STK500v2; in that case you would replace:
Code: [Select]
-c buspiratewith
Code: [Select]
-c stk500v2
I recently needed to program some devices and don’t have a dedicated ICSP (I’m an MSP430 guy myself), so I figured the easiest way was creating an Arduino shield with a 28-pin socket, completely forgetting the Bus Pirate could do it! So I spent a night wiring up a Proto Shield I had laying around, and then a few hours banging my head against the wall when I couldn’t get it to work reliably. I thought maybe the target device needed a crystal, so I added that. Still nothing. By chance I saw the BP in the list of supported avrdude programmers and decided to wire it up directly and see if it worked. I also decided to use a different, fresh chip instead of the one in the Arduino-Programmer. It worked! …it also worked in the Arduno-Programmer… Turns out I had fried the original chip I was working with at some point. *Doh!*
At any rate the Bus Pirate works much better and is much less fiddly, as I can clip the probe leads directly to IC pins without putting it in a socket (which requires removing it, which always leads to bent pins; I’m too cheap to order a ZIF socket for something I’ll use once in a blue moon).
