mpu-servocontrol 0.1.2

beta version

MPU6050 Servocontrol (Raspberry Pi)

A small library to control a servomotor via an mpu6050 accelerometer . This library is based on the i2c connection and it is necessary to install the smbus module first. In fact, it is made only for raspberry pi systems .

Installation

First get smbus

pip install smbus

Then install mpu-servocontrol

pip install mpu-servocontrol

ServoControl class

ServoControl(servo_pin , i2c_port)

i2c_port=1 or 0 (depends of raspberry pi model) and for servo_pin pick a pin that have pwm

Initialize mpu sensor

ServoControl.setup_mpu()

Pick an axis (x/y/z) This method returns data that has been read

ServoControl.read_data_x() / .read_data_y() / .read_data_z()

Start servocontrol As argument put the data read from an axis

ServoControl.start_control(data)

Stop servocontrol

ServoControl.stop_control()

Get started

This is an exemple

import RPi.GPIO as g
from mpu_servocontrol.mainclass import ServoControl    #Import
import time
import sys


g.setwarnings(False)
g.setmode(g.BCM)

sc = ServoControl(servo_pin=12 , i2c_port=1)        #Make an instance of ServoControl class
sc.setup_mpu()                                      #Initialize mpu6050 accelerometer

try:
    while True:                                     #Main loop
        data = sc.read_data_y()                     #Read data from y axis
        sc.start_control(data=data)                 #Start
        time.sleep(0.08)                            #Add a little delay
except KeyboardInterrupt:
    sc.stop_control()
    g.cleanup()
    sys.exit(0)                                     #Press ctrl+c to stop
