Abstract

The main aim of this project will be to provide a high level interface for the Pulse Width Modulation output pins of the OMAP3 found on the BeagleBoard. Another aim will be to push this driver upstream(the Linux-OMAP tree). Two applications will be developed to demonstrate the use of this driver:

  • Motor control using PWM signals generated by the BeagleBoard using the PWM driver.
  • Writing a glue layer for ALSA to communicate with the PWM driver and output sound from the PWM output pins.

Build and Run instructions

  • Clone my git tree for the driver from [1].
  • Follow the README document [2].
