I2C Servo Controllers
Related Config File Sections:
MPF currently supports PCA9685/PCA9635 based servo controllers via I2C. One example for such a controller is the Adafruit 16-Channel 12-bit PWM/Servo Driver. You can use any I2C platform supported by MPF (see I2C Platforms in MPF).
Overview video about servos:
1. Installing I2C Servo Controllers
Connect the controller to the I2C port and add the following config section:
hardware: servo_controllers: i2c_servo_controller
0x40 is actually the default I2C address for this chip but it might be different for some chips.
2. Add your servos
Add your servos to config:
servos: servo1: number: 0 # first servo on controller
All these config options are explained in-depth in the servos: section of the config file reference.
You can also provide an I2C address per servo:
servos: servo_on_controller_63_0: number: 63-0 # first servo on board with ID 0x3F / 63 servo_on_controller_63_1: number: 63-1 # second servo on board with ID 0x3F / 63
