Starts the fixed-frequency DAC
Not available on the imp005
Call this method to tell the configured DAC to begin converting the data in its buffer(s). Starting the fixed-frequency DAC will raise an error if the device has not yet been configured using fixedfrequencydac.configure().
Output at 0.5kHz from pin 5 on an imp001 or imp002 for 40 seconds. By way of illustration, this code generates a sinusoidal output with an amplitude that also varies sinusoidally. This example recycles the buffers and they are added back in the callback.
