Control scripts for experiment in Fujii team

Installing USB-RS232C convertors

In this scripts, we will use serial port. We need some package and drivers for it,

Python packages

• pyserial

conda install pyserial

Ubuntu

Install ftdi driver

• libusb-1.0 apt-get install libusb-1.0

With ftdi device

• create /etc/udev/rules.d/11-ftdi.rules

With PL2303 device

Find the manufacturer ID and product ID

lsusb

It shows something like the following

Bus 002 Device 005: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

In this case, the manufacturer ID is 067b and product ID is 2303.

Create a file /etc/udev/rules.d/pl2303.rules and add the following line

# PL2302 USB2.0-RS232 convertor
SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", GROUP="usbtmc", MODE="0660"

Then, restart.

Usage

Find the COM port

dmesg | grep tty

It should be like /dev/ttyUSB0

Windows

Install ftdi driver

Find the COM port. It will look like COM3
