Python Copper¶
Copper is a module aimed at providing low-level hardware abstraction layers (HAL) as Python modules. Copper aims to create a simple and well designed API that will allow engineers with a diversity of skill sets and skill levels to develop complex eletromechanical systems from common off-the-shelf components.
Be lazy like a fox: control hardware with readable code.
>>> from copper.usb import firmata
>>> from copper.i2c import pca9685
>>> uno = firmata.ArduinoUno('95530343434351A002E0')
>>> uno.i2c_enable()
>>> servo = pca9685.Pca9685(i2c=uno.i2c, address=0x40)
>>> servo.set_pwm_duty(channel=0, duty=0.8)
