PyPulsePal

Python API for the PulsePal open-source pulse train generator

This package provides an API to the PulsePal hardware. This API is a re-implementation of the original PulsePal Python 3 API that draws from the pybpod-api communication protoool.

Example usage

script/function

from pypulsepal import PulsePal

serial_port = "/dev/ttyACM0"  # for unix or "COM"-style port names for Windows

# Create PulsePal object
pp = PulsePal(serial_port=serial_port)

# Set parameters

## Manually
pp.program_one_param(channel=2, param_name="phase1Duration", param_value=.002)

## Via convencience functions
pp.set_resting_voltage(channel=2, voltage=4.2)

# Upload parameters
pp.upload_all()

# Trigger channels
pp.trigger_selected_channels(channel_2=True, channel_4=True)
pp.trigger_all_channels()

# Stop outputs
pp.stop_all_outputs()

# Save settings (also done automatically on disconnect)
pp.save_settings()

as context manager

import time
from pypulsepal import PulsePal

with PulsePal(serial_port="/dev/ttyACM0") as pp:
    # set params
    pp.upload_all()

    # do something
    time.sleep(2)

Write default params to all channels

from pypulsepal.write_tests import write_default_settings

write_default_settings(serial_port="/dev/ttyACM0")

Write (funky) test params to all channels

from pypulsepal.write_tests import write_test_settings_for_manual_check

write_test_settings_for_manual_check(serial_port="/dev/ttyACM0")

This work is derived from the Sanworks PulsePal Python API (commit: 5bb189f).

The architecture of the API is imported and inspired by the pybpodapi.com.arcom module from the pybpod-api.

For changes from the original implementation, see the git history since commit 972bc1e.

TODO

• Simplify parameter dicts in definitions: into nested dict with first level for name, then standard sub-dict (default value, dtype, dtype legacy(model 1), scaling, )
• Complete API functions with all PulsePal opcodes, e.g. for Arduino logic levels (see PulsePal USB v2 opcode list)
• Move PulsePal hardware settings to init and remove defaults for easier upgrade in future
• API function to accept list of dicts (from json settings file)
  • to make overwrites on channels to get from value-based logic to channel parameter sets
  • add write function to save all settings to json for documentation
