Python library for the PMW3901 optical flow sensor
Project description
PMW3901 / PAA5100JE 2-Dimensional Optical Flow Sensor
Installing
Stable library from PyPi:
- Just run
python3 -m pip install pmw3901
Latest/development library from GitHub:
git clone https://github.com/pimoroni/pmw3901-python
cd pmw3901-python
./install.sh
Usage
The PAA5100JE has a slightly different init routine to the PMW3901, you should use the class provided to ensure it's set up correctly:
from pmw3901 import PAA5100
And for the PMW3901, continue using the old class:
from pmw3901 import PMW3901
The example motion.py
demonstrates setting up either sensor, and accepts a --board
argument to specify which you'd like to use.
