Joy-Pi Advanced Library for Raspberry Pi

This library is a collection for the Raspberry Pi for several modules on the Joy-Pi Advanced. See here for more information.

Included modules

This library includes the following modules:

• ADC
• Gyroscope
• Barometer
• Button Matrix
• Color Sensor
• LED Matrix
• Servo Motor
• Stepper Motor

Dependencies

This library has some dependencies which are used to control the modules of the Joy Pi Advanced. To use this library, you will need to install the following dependencies:

• rpi_ws281x - for the LED matrix - with pip install rpi_ws281x
• Adafruit CircuitPython BusDevice - for the barometer - with pip install adafruit-circuitpython-busdevice
• Adafruit_CircuitPython_MCP230xx - for the button matrix - with pip install adafruit-circuitpython-mcp230xx

Installation

pip install JoyPi-Advanced-RaspberryPi

Library Guide

ADC

• adc(bus = 0, device = 0) - initialize ADC with default values
• open() - starts communication
• read_value(channel) - returns raw value from a selected channel
• read_voltage(channel, value=None) - returns measured voltage from a selected channel, raw value can also be calculated into voltage with this method
• close() - ends communication

Gyroscope

• gyroscope(bus = 0, device = 2)- initialize gyroscope with default values
• open() - starts communication
• close() - ends communication
• getTemperature() - returns measured temperature
• getTilt() - returns the tilted direction
• scale_Factor(scale) - sets scale factor of the gyroscope (0, 8, 16 or 24)

Barometer

• barometer(i2c: busio.I2C, i2c_address = 0x77, resolution=4096) - initialize barometer with default values
• get_pressure() - returns the measured pressure
• get_temperature()- returns the measured temperature
• get_altitude(reference_pressure = 1013.25) - return the calculated altitude with the measured pressure and your local pressure (reference_pressure)

Button matrix

• buttonmatrix(i2c: busio.I2C, i2c_address = 0x22)- initialize button matrix with default values
• getKey() - returns the pressed button
• clearMemory() - clears class variable calculated
• calculate() - method to use the button matrix as a calculator

Color sensor

• colour(i2c_address = 0x10)- initialize colour sensor with default values
• enableSensor() - start communication
• disableSensor()- end communication
• getRGBW() - returns measured RGBW values
• setIntegrationTime() - set integration time (0-40ms, 1-80ms, 2-160ms, 3-320ms, 4-640ms or 5-1280ms)
• forceMode() - forces measurement mode
• autoMode()- automatic measurement mode
• readAll() - returns RGB colours as well as raw values

LED matrix

• LEDMatrix( pin = 18, brightness = 100)- initialize LED matrix with default values
• clean() - clears the LED matrix
• setPixel(position, colour) - sets specific pixel to a selected colour
• RGB_on(colour) - sets the complete matrix to one selected colour
• rainbow(wait_ms=20, iterations=1) - rainbow effect on the whole matrix with default values
• colourWipe(colour, wait_ms=50) - Move selected colour pixel by pixel onto the matrix with default speed
• theaterChase( colour, wait_ms=50, iterations=10) - chaser animation with a selected colour with deafult speed
• show() - displays set pixels
• demo1() - demo program version 1
• demo2() - demo program version 2

Servo motor

• servomotor(pin = 18, position = 0) - initialize servo motor with default values
• setDirection(set_pos, speed = 5) - moves servomotor to a selected position in specified speed (1-5 : slowest - fastest)
• setPosition(pos) - moves servomotor to a selected position with default speed
• setHome() - sets servomotor to start position
• getPosition() - returns position of servo motor
• end() - moves servo into start position, stops communication and cleans up communication

Stepper motor

• stepmotor(pin1 = 22, pin2 = 23, pin3 = 24, pin4 = 4)- initialize step motor with default values
• turnSteps(steps) - turns a selected amount of steps
• turnDegrees(deg) - turns a selected amount of degree
• turnDistance(dist, rad) - rotates by distance value
• close() - close all used pins
