Enable PCA9685

Beginner Topic used frequently in Bottango workflows.

Big idea

To use the PCA9685 servo driver with Bottango, you need to enable its module.

Upload in app if you can, or modify the modules file and reupload to enable PCA9685 Support.

Uno R3 / Nano / Mega: Use The App

If you’re using an Arduino Uno R3, Nano, or Mega, you can just use the desktop app to flash the firmware with the module enabled. Be sure to enable the switch “Include Adafruit PCA9685 PWM Servo Driver Library” on the bottom of the uploading menu.

Enable Using The Modules Source

If you’re using the source code, you’ll edit the required line in the BottangoArduinoModules.h file. See Changing Modules.

Remove the ”//” characters from the start of the line:

BottangoArduinoModules.h

// #define USE_ADAFRUIT_PWM_LIBRARY      //uncomment this line to enable the Adafruit PCA9685 Servo Driver (I2S and pin)

so that it is enabled:

BottangoArduinoModules.h

#define USE_ADAFRUIT_PWM_LIBRARY      //uncomment this line to enable the Adafruit PCA9685 Servo Driver (I2S and pin)

Then save the file, and reupload the firmware to your device.
