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.This can be done using the following commands:
git clone git://github.com/neo01124/omap3-pwm.git cd omap3-pwm/branch -b branch
- A cross compiling environment will be needed for compiling the driver. Instructions below work with OpenEmbedded but can adapted for codesourcery as well.
