1) Arm Bink Leds

• The LEDs are blink via ARM memory.
• GPMC has been used between ARM and FPGA for memory Transfer
• Further the GPMC protocol has been converted to Wishbone protocol
• Detailed Steps

2) Bink Leds

• The LEDs are blink via simple counter logic
• Detailed Steps

3) Bar Graph

• This Example is the template for wishbone intercon
• The testcase consist of:
  1. Wishbone Slave 1: PMOD 3 (Bar Graph 0)
  2. Wishbone Slave 2: PMOD 4 (Bar Graph 1)
• Address Map

        Wishbone Memmap
        Slave 0:  0x0000
        Slave 1:  0x0040
  

• Wishbone intercon automatically routes signals and data to the appropriate slave depending on the memmap
• Detailed Steps

4) VGA

• In this example, I have displayed wishbone VGA Patterns on a monitor.
• For this Example we have used following PMOD: Digilent-VGA-PMOD
• VGA PMOD is connected to the beaglewire P3, P4 Pmods.
• pinmap can be found in pcf file.
• It is connected upside down to port3 and port4.
• Detailed Steps
• VGA Pattern Table:

• Demo Video of VGA can be found here: Imgur

5) Pong on the FPGA:

• For this Example also we have used following PMOD: Digilent-VGA-PMOD
• VGA PMOD is connected to the beaglewire P3, P4 Pmods.
• pinmap can be found in pcf file.
• It is connected upside down to port3 and port4.
• Detailed Steps
• Switches Information:
