Datasheet

If you've installed WinAVR (http://adafru.it/aI2) or similar (say for Mac (http://adafru.it/aI1)

or Linux (http://adafru.it/aWW) ) , it'll be in something like C:\WinAVR\bin\avrdude.conf or

C:\WinAVR\etc\avrdude.conf if you aren't sure where it is, but you have avrdude

installed, you can runavrdude -c xyzwhich will dump the programmer list, if you look to the

right, the name of the conf file will be printed

A common reason for wanting to program an AVR is to put the Arduino bootloader on

there, in which case, you may not have WinAVR installed. Luckily, avrdude is there, its just

'hidden' in the IDE package (for Mac users,you need to actually "explore" the App) if you're

running windows, go to the folder where you have the IDE installed and go into the

hardware\tools\avr\etc folder to open up avrdude.conf

OK! Now that you have avrdude.conf open, find the string ponyser, then add the following

bold text right before hand so the avrdude.conf looks like this:

# some ultra cheap programmers use bitbanging on the

# serialport.

# PC - DB9 - Pins for RS232:

# GND 5 -- |O

# | O| <- 9 RI

# DTR 4 <- |O |

# | O| <- 8 CTS

# TXD 3 <- |O |

# | O| -> 7 RTS

# RXD 2 -> |O |
