AVR Programming
On this page I will put some information about AVR programming while I learn how to program AVR micro-controllers myself. It will probably mostly work as a note-book for my own use, but the information might be of use to others, therefore this page.
AVR Dragon
AVR Dragon is low cost development board from Atmel, see http://www.atmel.com/tools/avrdragon.aspx for more information.
Setup
To be able to use avrdragon as a regular user you need to create a
file in /etc/udev/rules.d/. I named it 90-avrdragon.rules. In this
file you should add the following (tested on Fedora 22), all in one
line:
SUBSYSTEM=="usb", ATTR{idVendor}=="03eb", ATTR{idProduct}=="2107", GROUP="users", MODE="0666"
This will set the mode of the AVR Dragon USB port to read+write for user, group, and all.
Run the following command as root to reload the udev configurations:
udevadm control -R
Getting started
Some usable web pages to read:
Misc information
Fuses
Use Fuse calculator to get the correct values for avrdude. To see the current setting do the following:
avrdude -p m1284p -c dragon_jtag -P usb -v
Programming
Setting fuses (get the numbers for the different fuses from above):
avrdude -p m1284p -c dragon_jtag -P usb -U lfuse:w:0x42:m -U hfuse:w:0x99:m -U efuse:w:0xff:m
To program the file flash.hex to the micro controller, do:
avrdude -p m1284p -c dragon_jtag -P usb -e -U flash:w:flash.hex
