As for pwm if duty cycle is to fast you might not see a led turn on ask for a scope. Your Original post discussed I2C command's I'm not familiar with that part but not seeing the duty cycle or using a LED seems brutal to require for someone starting out. Perhaps you are being hazed or the person assignment is unrealistic. My self I'd suspect the code was left incomplete hence start with Original set-up with a Led driver get it working.

Part 1. Program the device to generate signals to turn LED15 to full ON. Should be measurable voltage from the number 15 signal pin on the servo board. Part 2. Develop commands you send to PCA9685 to intialize it for the correct frequency for your servo, set up a timer on the BBB to control delays, and intialize the BBB User LEDs. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
