Avrdude 6.1

I just installed the latest version of Raspbian Jessie 2015-11-21 for my Pi 2's. I found that now when I installed the arduino package, it comes with avrdude 6.1. So I don't need to link to the adafruit repository anymore. Here is a list of the steps I take to install Jessie, Arduino, Arduino-mk, and check that I can communicate between the Arduino & Raspberry Pi 2 via Serial. You'll note that I clone my git repository where I keep all of my files as I'm working on them. I find this extremely useful since I'm working on the files on my Pi2 or Gertduino/PiB at home, or the same setup that I have at work:

1. Install Jesse 2015-11-21
2. Go thru the configuration
   (Menu > Preferences > Raspberry Pi Configuration)
1. Under the System Tab:
1. Expand the filesystem
2. Change the pi password
3. Change the Pi Hostname
4. Don’t automatically login to ‘pi’ user
2. Under the Interfaces Tab:
1. Camera = Disable
2. SSH = Enable
3. SPI = Enable
4. I2C = Enable
5. Serial = Disable
3. I don’t change anything under the Performance Tab
4. Under the Localisation Tab:
1. Change the locale to Canada (English)
2. Set the Timezone to Canada (America) > Mountain (Edmonton)
3. I’m still having a problem with changing the keyboard layout
1. It is a noted problem on the Raspberry Pi Forum
2. Still using sudo raspi-config to config to Canada > English
3. sudo apt-get update
4. sudo apt-get upgrade
5. sudo adduser robin
6. sudo visudo to give robin the same rights as pi user
7. sudo apt-get install arduino-mk
8. sudo apt-get install arduino (add robin to dialout group)
9. Make a link to the Arduino.mk file:
   ln -s /usr/share/arduino/Arduino.mk ~/Arduino.mk
10. Copy the original avrdude.conf file into my home directory
1. cp /etc/avrdude.conf ~/avrdude_gpio.conf
11. Modify it to work with the GPIO pins
1. nano ~/avrdude_gpio.conf
12. Aff the following lines at the end of the file:
1. # Linux GPIO configuration for avrdude
2. # Change the lines below to the GPIO pins connected to the AVR
3. programmer
4.  id = "pi_1";
5.  desc = "Use the Linux sysfs interface to bitbang GPIO lines";
6.  type = "linuxgpio";
7.  reset = 12;
8.  sck = 24;
9.  mosi = 23;
10.  miso = 18;
11. ;
13. With the Arduino connected to the Raspberry Pi, run the following line to make sure the Raspi can see the arduino:
    sudo avrdude -p atmega328p -C ~/avrdude_gpio.conf -c pi_1 -v
14. git clone https://github.com/robingreig/raspi-git
15. cp -r ~/raspi-git/Python ~ (to copy the Python directory to my home)
16. cp -r ~/raspi-git/Uno ~ (to copy the Uno directory to my home)
17. Goto the .hex file @ ~/Uno/Serial/Voltages/build-uno/Voltages.hex & run:
    sudo avrdude -p atmega328p -C ~/avrdude_gpio.conf -c pi_1 -v -U flash:w:Voltages.hex:i
    
18. If you overwrite the bootloader, reload it by going to:
    cd /usr/share/arduino/hardware/arduino/bootloaders/optiboot/
    and running the avrdude line with the optiboot_atmega328.hex file
