 Create a program using the Blackfin BF533 that allows the user to “move” the source of input sound.

 PF9: Move Left Direction  PF10: Return to Center  PF11: Move Right Direction  Lights indicate which of the 6 speakers are “on.”  1:Front Left  2:Front Right  3:Front Center  4:Back Center  5:Back Left  6:Back Right

 TWI vs TDM  TDM is used as TWI does not allow all 3 output channels to be used.  SW9 pins 5 and 6 MUST be switched off to allow TDM mode

 9 Total “Zones”  Switch/Case statements used Zone #Active Speaker ChannelsZone Name 0Back Right, Back Center;Back Right 1Front Right, Back Right;Pure Right 2Front Center, Front Right;Front Right 3Front Right, Front Center, Front Left;Front 4 Front Left, Front Center, Front Right; Back Left, Back Center, Back Right;Center 5Front Left, Front Center;Front Left 6Front Left, Back Left;Pure Left 7Back Left, Back Center;Back Left 8Back Left, Back Center, Back Right;Back SpeakerChannel Front LeftiChannel0Left Front RightiChannel0Right Front CenteriChannel1Left Back CenteriChannel1Right Back LeftiChannel2Left Back RightiChannel2Right

 Light Address Table FLFRFBBLBRFlash Address x x x x x3F x x x x38

 Modified TDM Talkthrough Example  Initialize  Init_Flash ▪ Added *pFlashA_PortB_Dir = 0x3f; to initialize the Flash Memory for the lights  Init_Interrupts ▪ Modified SIC values to allow buttons and sound ▪ Added register handler for Button Flags  Init_Flags ▪ Added entire function to initialize flags for buttons

 ISR  Added variables for Channel 2 Left and Right Out.  Added Interrupt Handler for FlagA ▪ Created algorithm to handle button presses ▪ Included switch/case for lights in FlagA interrupt handler  Main  Added Init_Flags();  Added variables for counter, and Channel 2 Left and Right out

 Process_Data  Created Switch/Case algorithm to change zones when buttons are pressed  Added Prototype Functions and Variables to header “Talkthrough.h”

 Thank you for your time and consideration.
