Python-OC05

The OC05 xChip is an 8-channel servo motor driver. It is based on the popular PCA9685 manufactured by NXP Semiconductor. It is supported by a BU33SD5 regulator to drive and accurately control up to 8 servo motors on a single module and act as system power supply. The module has 8 standard 2.54 mm (0.1") servo headers, plus 1 standard 2.54 mm (0.1") battery/BEC input header.

from xCore import xCore

# OC05 instance
OC05 = xOC05()

# configure OC05 with frequency of 60Hz
OC05.init(60)

while True:
    OC05.setServoPosition(1, 0)     #  position servo to the right
    xCore.sleep(50)
