This is a Python interface for the Firmata protocol used on the MPU. You can install it
by typing pip install PyMata in the console. At the time of writing, LinkIt Smart 7688
Duo supports version pymata-2.1.
Note: The LinkIt Smart 7688 Duo needs to be in Station mode in order to use pip to install the
pyFirmata and PyMata interface, please see section 4.3.2, "Station Mode" for details on how to set
station mode.
6.6.4. PyFirmata Approach
Uploading The Arduino Firmata Sketch
•
This section describes setting up Arduino to listen for Firmata commands from the Serial
port.
Open the Arduino IDE 1.6.5
1)
In Arduino IDE, open the example
2)
This built-in example is for Arduino Uno, which uses
However, LinkIt Smart 7688 Duo uses
Therefore, you'll need to change the listening port of this example from
Serial to Serial1.F
Firmata.begin(57600);
And change it to:
3)
Serial1.begin(57600);
Firmata.begin(Serial1);
Upload the sketch. After uploading the sketch, Arduino is ready to receive commands
4)
from the Linux side.
Running Your Blink Example Using pyFirmata

After
In the console, create a python file called

from pyfirmata
from time import
board = Arduino('/dev/ttyS0')
print "Start blinking
while True:
board.digital[13].write(1)
sleep(0.5)
