PyPulsePal

Python API for the PulsePal open-source pulse train generator.

→ Full documentation

Example usage

Load and apply a saved config file:

from pypulsepal import PulsePal
from pypulsepal.config_io import load_config

cfg = load_config("my_params.json")   # or .yaml
with PulsePal.from_config(cfg, serial_port="/dev/ttyACM0") as pp:
    pp.trigger_selected_channels(channel_1=True)

Standard instantiation:

import time
from pypulsepal import PulsePal

pp = PulsePal(serial_port="/dev/ttyACM0")
pp.channel_configs[0].phase1Voltage = 5.0
pp.channel_configs[0].pulseTrainDuration = 1.0
pp.sync_all_params()
pp.trigger_selected_channels(channel_1=True)
time.sleep(1)
pp.stop_all_outputs()
pp.close()

As a context manager (saves settings and closes on exit automatically):

import time
from pypulsepal import PulsePal

with PulsePal(serial_port="/dev/ttyACM0") as pp:
    pp.channel_configs[0].phase1Voltage = 5.0
    pp.channel_configs[0].pulseTrainDuration = 1.0
    pp.sync_all_params()
    pp.trigger_selected_channels(channel_1=True)
    time.sleep(1)
    pp.stop_all_outputs()

Installation

pip install pypulsepal
