Page: 14 / 39

3.1.3 Connect to Arduino Duemilanove/Diecimila
1) In Duemilanove/Diecimila, the mega avr uart interface is connected to the FTDI chip, we have
to disconnect them as shown in below picture:
2) Add a “Duemilanove Yun” board type in the file: Arduino\hardware\arduino\avr\board.txt.
user can use the UnoYun board type if they has mega328p. for
mega328/mega168/mega168p, they can modify the upload.maximum_data_size/
upload.maximum_size and build.mcu accordingly.
3) Put the Yun Shield on top of Duemilanove and power it via DC jack.
3.1.4 Connect to Arduino Mega2560
1) In Mega2560, the uart connection between mega2560 and mega16u2 will influence the
bridge feature with Yun Shield. So we have to disconnect it by set the mega16u2 into reset
mode. As below:
2) Add a “ Mega2560 Yun ” board type in the file: Arduino\hardware\arduino\avr\board.txt. as
below and reopen the Arduino IDE:
