  1. Project Intensity By Hani Kably

  2. Objectives • Learn how to display the intensity on the LEDs for two channels (two different patterns). • Learn how to display the intensity on the LEDs for only one channel (four different patterns).

  3. Hardware/Software Used • ADSP-BF533 • Blackfin VisualDSP++ 5.0 • Speakers • Personal Computer • Cables

  4. Button Functions PF8 (default state): the LEDs display the intensity peripherally (stereo). • The first pattern displays the intensity of the left channel on the LEDs from the middle to the left, and the right channel on the LEDs from the middle to the right. • The second pattern displays the intensity of the left channelon the LEDs from the far left to the middle, and the right channel on the LEDs from the middle to the far right.

  5. PF9 (second button): the LEDs display the intensity of the left channel only. • The first pattern displays the intensity on the LEDs from the far left to the far right. • The second pattern displays the intensity on the LEDs from the far right to the far left. • The third pattern displays the intensity on the LEDs from the middle to the left and right. • The fourth pattern displays the intensity on the LEDs from the far left to the middle and from the far right to the middle.

  6. PF10 (third button): the LEDs display the intensity of the right channel only. • The first pattern displays the intensity on the LEDs from the far left to the far right. • The second pattern displays the intensity on the LEDs from the far right to the far left. • The third pattern displays the intensity on the LEDs from themiddle to the left and right. • The fourth pattern displays the intensity on the LEDs from the far left to the middle and from the far right to the middle.

  7. General Guidelines • Any globally defined variable must be also be externally introduced in the header file. • Any globally defined function must be also be introduced in the header file. • It’s important to use the OR logic between two functions that use LEDs at the same time! Otherwise they will conflict and result in having only one function working.

  8. Results and Conclusion • There were few obstacles, but I managed to overcome them. • The project works as expected without any errors or mishaps. • This project was a good experimental learning tool in which helped me aspire and grow. • I feel extremely confident about making any other project concerning the ADSP-BF533.
