Utils

Set of utils to drive the lab equipment remotely. The main use cases are

PiLas laser

Class PiLas in Lab5015_utils.py Allows to turn the laser ON and OFF and change basic parameters such as the tune and the frequency. A script for a quick edit of the settings is also available:

python3 drivePiLas.py --power=1 --tune=50  --freq=50000

SMC chiller

Class SMChiller in Lab5015_utils.py Allows to turn the chiller ON and OFF and check and change the temperature. A script for a quick edit of the settings is also available:

python3 driveChiller.py --power=1 --temp=19.2

The following script uses a PD approach to reach and maintain the desired temperature:

python3 setBoxTemp_PID.py --target 22

Bind an instrument to a device name

Check instrument characteristics

dmesg | grep ttyUSB
udevadm info --name=/dev/ttyUSBx --attribute-walk

Create a file /etc/udev/rules.d/99-usb-serial.rules with something like this line in it:

SUBSYSTEM=="tty", ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678", SYMLINK+="your_device_name"

test the change:

sudo udevadm trigger
udevadm test -a -p  $(udevadm info -q path -n /dev/your_device_name)
