AVR Toolchain

Debian/Ubuntu

• Needed programs for running the code under debian unstable:

   apt-get install avr-libc gcc-avr

• avrdude is available in the same name:

  apt-get install avrdude

• libusb is needed for running the host code for the flower:

  apt-get install libusb-1.0-0-dev

(tested on debian unstable, should also run under ubuntu)

Gentoo

• You will need to install crossdev (which will do all the rest for you) and avrdude to flash your µC.
• The avr toolchain is broken (for some years already [1]), but fortunately there is a workaround in the Gentoo wiki.

Udev Rules

if you want to connect to the device as normal user, you have to create a little udev rule. For debian like systems create a file in the folder /etc/udev/rules.d and reload udev (/etc/init.d/udev reload):

$ cat /etc/udev/rules.d/z99_atmel.rules 
# Atmel AVR ISP mkII
SUBSYSTEM=="usb", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="2104", GROUP="plugdev", MODE="0660" 
# usbprog bootloader
ATTRS{idVendor}=="1781", ATTRS{idProduct}=="0c62", GROUP="plugdev", MODE="0660"
# USBasp programmer
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05dc", GROUP="plugdev", MODE="0660"
# USBtiny programmer
ATTRS{idVendor}=="1781", ATTRS{idProduct}=="0c9f", GROUP="plugdev", MODE="0660"
