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:
| {SW3, USR1, USR 0} | Pattern on VGA |
|---|---|
| 000 | Disable |
| 001 | All Red |
| 010 | All GREEN |
| 011 | All Blue |
| 100 | Checkboard White/Black |
| 101 | Color Bars |
Flash the FPGA with VGA example bitstream
cd Beaglewire/examples/vga
# If the fpga tools present on BBB
make
# Else scp the .bin file in Beaglewire/examples/vga
# In host computer go to Beaglewire/examples/vga
# make
# Command to send it to FPGA:
# scp vga.bin debian@192.168.6.2:/home/debian/Beaglewire/examples/vga
# Loading SPI flash after FPGA reset, it will be boot up on SPI.
make load_spi
# Reset the FPGA for running bitsream (RST Button on BeagleWire)
