pantilt 0.0.1

A pantilt control utility

中文文档

pantilt

This is a tool kit containing Python utils

1. for driving servos,
2. for controlling camera at a two-servos pan tilt by widgets in jupyter notebook and a PS4 Joystick.

Quick Guide

1. To Initiate a Servo

from pantilt import Servo
s1 = Servo(channel=14, bus=0, max_angle=180, min_angle=0)

channel is number that servo has connected to PCA9685 board;
bus can be 0 or 1 or even 2;
max_angle min_angle is upper and lower limit we set for the servo.

s1.to_angle(45)
s1.reset()
s1.change_reset(0)
s1.add()
s1.sub(3)
s1.read()
s1.change_unit(30)
s1.to_min()
s1.to_max()

.to_angle() will turn to a angle;
.reset() will turn servo back to the default angle, which is (max_angle+min_angle)/2 as default;
.change_reset() This will change the default reset angle to input number.
Leaving bracket blank as .change_reset() will apply the current angle.

.add() changes the servo by adding one unit of angle, which is 10 degree as default.
.sub() changes the servo by subtracting one unit of angle;
An integer in its bracket means how many unit it will act on.
.change_unit() will change how many degree it turn for one unit.

.read() can read the current angle of the servo.
.to_min() will turn to the minimum angle.
.to_max() will turn to the maximum angle.

You can open a jupyter notebook file, servo_demo.ipynb, to have a try on this tool kit.

2. To Initiate a Pan Tilt

Its methods to control two servos at a pan tilt is similar to control a servo, here is a jupyter notebook file pan_tilt_demo.ipynb

3. Camera Pan Tilt

Walkthrough is here cam_pan_tilt_demo.ipynb

Install

1. Clone the project, please rememeber to clone with parameter —recurse-submodules, because pantilt project referene another submodule bcam.

git clone --recurse-submodules  https://github.com/youyoubilly/pantilt.git

2. Install pantilt

STL 3D Model

You are welcome to download the stl file I designed for this simple pan tilt of CSI camera, and 3D print it out.
You may adjust the stl model for different use.
