Python resources and API for 3Space sensors from Yost Labs Inc.

API and Resources for Yost Labs 3.0 Threespace sensors.

Installation

python -m pip install yostlabs

Basic Usage

USB

from yostlabs.tss3.api import ThreespaceSensor

#Will auto detect a 3-Space sensor connected to the machine via a USB connection
sensor = ThreespaceSensor()

result = sensor.getPrimaryCorrectedAccelVec()
print(result)

sensor.cleanup()

BLE

from yostlabs.tss3.api import ThreespaceSensor
from yostlabs.communication.ble import ThreespaceBLEComClass

#PUT YOUR SENSORS BLE_NAME HERE
ble_name = "YL-TSS-####" #Defaults to the lowest 4 hex digits of the sensors serial number
com_class = ThreespaceBLEComClass(ble_name)
sensor = ThreespaceSensor(com_class)
#sensor = ThreespaceSensor(ThreespaceBLEComClass) #Attempt to auto discover nearby sensor

result = sensor.getPrimaryCorrectedAccelVec()
print(result)

sensor.cleanup()

Communication

The ThreespaceSensor class utilizes a ThreespaceComClass to define the hardware communication interface between the device utlizing this API and the Threespace Sensor. Currently only the ThreespaceSerialComClass is available for use with the API. New ComClasses for different interfaces will be added to the communication package in the future.

To create your own ThreespaceComClass, take a look at the necessary interface definitions here and the Serial implementation here.
