Example 4: Running

It has taken a lot more effort to describe how to use a typical device driver

than it does to actually use it! To observe the device driver in action, open

and build the Example_4.dpj project located in

<install_path>\Blackfin\Examples\ADSP-BF548 EZ-Kit Lite\Getting

Started Examples\Example_4

. On the EZ-KIT Lite, plug a pair of head-

phones or powered speakers into the audio socket labelled LINE OUT (it is

the single-tier socket beside the two double-tier sockets) and press F5 to

run the project. You will hear the phrase “An orange-colored sky” spoken

five times with a short pause between repetitions.
