VGA Display Port
The MicroBlaze Development Kit board includes a VGA display port via a J15 connector.
Connect this port directly to most PC monitors or flat-panel LCDs using a standard
monitor cable. As shown in Figure 6-1 , the VGA connector is the left-most connector along
the top of the board.
The Spartan-3E FPGA directly drives the five VGA signals via resistors. Each color line has
a series resistor, with one bit each for VGA_RED, VGA_GREEN, and VGA_BLUE. The
series resistor, in combination with the 75: termination built into the VGA cable, ensures
that the color signals remain in the VGA-specified 0V to 0.7V range. The VGA_HSYNC
and VGA_VSYNC signals using LVTTL or LVCMOS33 I/O standard drive levels. Drive
