 +  avrdude -P usb -c dragon_isp -p attiny13 -t 
 +==== fuse settings ==== 
 +  * see at this page for info about setting the fuses: [[http://www.engbedded.com/fusecalc]] 
 + 
 +==== Debugging with Bus Pirate ==== 
 +Connect Bus Pirate with 1-wire device as follows: 
 +  * (Bus Pirate) MOSI -> (ATtiny13A) 1-wire data pin (to 47 ohm resistor) 
 +  * (Bus Pirate) GND -> (ATtiny13A) GND 
 +Because the ATtiny13A is not a genuine 1-wire ic, connect additionally: 
 +  * (Bus Pirate) +5v -> (ATtiny13A) +5v 
 + 
 +With Bus Pirate v4 an external pull-up resistor is not required. The board con be configured by software to have one. Use a terminal, configure speed to 9600 N81, 'new line' shall be only CR. Connect the Bus Pirate and enter the following commands:
