I installed UP_IP_Library.exe (classic 6.0.0 version), which supposedly has a VGA controller for the DE1 board.
Unfortunately, it only goes up to 320x240, not the 640x480 that is stated in the documentation. Looking at the SOPC tcl/ptf file shows that the 640x480 option was commented out:
# RADIO
# {
# title = "640 x 480";
# enable = 0;
# DATA
# {
# $P/VGA_RESOLUTION = "1";
# $P/PIXEL_ADDR_WIDTH = "19";
# $P/MEGA_PIXEL_SIZE = "0";
# $P/NUMBER_OF_BACK_BUFFER_BITS = "0";
# $P/BACK_BUFFER_RESET = "1h0";
# }
#
Any ideas why this was removed, or where the 640x480 version for the DE1 board can be found?
BTW, the VGA Controller in UP_IP_Library_8.0.exe (version 8.0.0) only supports DE2 and DE2-70, although its altera_up_avalon_to_external_bus_bridge component is a 25mhz clock generator... why this is useful when there's already a 25mhz clock on board is beyond me!)
