AN #156 - VGA AVR - BASCOM Video controller Print
VGA AVR - BASCOM-AVR VIDEO CONTROLLER by GIOVANNI DE LUCA
(delucagiovanni at interfree dot it)


My board allows to visualize images, text, lines and single pixel, on your pc monitor with a 640 x 480 pixels resolution, 64 colors, 60hz through usb-serial commands.

For this application I have used an atmega128 - 18 Mhz overclocked and a Fpga Cyclone with a clock of 27.175 Mhz, two speed static ram low cost, one 64MB mmc card, a usb-rs232 converter.

The FPGA has been used for producing the synchronism signals for the video-vga and the timing to write and read from videoram.

I have attached the files for its program in J-tag mode with ByteBlaster programmer or Parallax serial mode. The code is in VHDL-LANGUAGE and to edit VHDL code I used Quartus web edition by Altera.

Ciao from Italy, Sicily, Catania city, by Giovanni De Luca.
