AMTIUSBDeviceWrapper 1.1.2

Wrapper for AMTI USB Device library. Currently only supported on Windows Systems for 32 and 64 bit versions of the SDK. Use 64 bit dll if running 64 bit python interpreter and vice versa with 32 bit dll.

AMTIUSBDeviceWrapper

Description

A digestable wrapper API for communication with AMTI GEN 5 and Optima USB Devices in python that simplifies AMTI's API.

Getting Started

Dependencies

• Windows 7 64/32-bit and later
• Python V 3.9.13 and later
• AMTI USB Device SDK V 1.3

Installation

• Place AMTI DLL where convenient
• Recommended install

python3 -m pip install amtiusbdevicewrapper

Execution

Ignore build step if installing from pypi.

• Build and install the package

git clone https://github.com/Lenz-Lab/AMTIUSBDeviceWrapper
py -m build # Windows
# or...
python -m build # Unix

# Install the package
pip install C:/some-dir/AMTIUSBDeviceWrapper/amtiusbdevicewrapper-<>.whl

• Simple Initialization and Data Acquisition at 500 Hz Example

# Import and load library
from AMTIUSBDeviceWrapper import AMTIUSBDevice as amti
amti.AMTIUSBDevice.InitializeLibrary(dll_path=<path_to_dll>)

# Initialize and setup amti device for data acquisition
amti_device = amti.AMTIUSBDevice("gen5")
amti_device.init() # Default settings
amti_device.broadcastAcquisitionRate(rate=500)

amti_device.broadcastStart()
sleep(0.01) # wait 10 ms for signal conditioners to acquire data

# Get data matrix
data, sample_num = amti_device.getData(opt=1) # opt 1->caller allocates memory

amti_device.broadcastStop()

Help

Ensure that you are using a version of python compatible with this package. IO specific exceptions are likely a result of an incorrect path.
