I'm using PXFMINI on raspberry Pi 3 and installed escarlata on it. I want to use ROS to make some programs for showing feedbacks such as imu data and etc. And I want to write my own controller to drive a quadcopter. How can I disable functions that access to PWMs, because I want to send PWMs myself with PCA9685 and I2C?
Please help, I really need this.
