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).
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
