[solved] arduino via serial port

snufkin · March 2014

Hi
I am using open sesame with arduino microcontroller platform.
I am communicating with my arduino with pySerial library.

I am using the arduino to activate motors, but each loop when I write the command
ser = serial.Serial("com8", 9600)
It resets the arduino and its take few seconds that destroy my experiment(due to the arduino bootloader).

Is there any way to create the ser class of pyserial just once when I start the experiment
and call the serial.write command without creating a new class every time?

Hi!

Yes there is! Put the following inline_script somewhere at the beginning of your experiment:

import serial

# create a new serial device, under the exp dict
exp.ser = serial.Serial("com8", 9600)

Now use the following inline_script whenever you want to call the write method:

# do some stuff here
myvar = "000000000"

# call write!
exp.ser.write("myvar")

Good luck!
