 When the driver is first loaded the GPIO pins are configure to be outputs, and
 their pulse widths are set to 0.  This is so that servos don't jump to some
 arbitrary postion when you load the driver.  Once you know where you want your

 Please read the driver source for more details, such as which GPIO pin maps to

 The driver uses DMA channel 0, and PWM channel 1.  It makes no attempt to
 protect against other code using those peripherals.  It sets the relevant GPIO
