2.8 VGA and CLCD interfaces
The MPS2 and MPS2+ FPGA Prototyping Boards support VGA and CLCD video output.
Overview of the VGA interface
The VGA interface consists of a VGA controller in the FPGA, a passive resistor network, and an output
VGA port. The VGA output has 4 bits per channel color depth.
Overview of the CLCD interface
The CLCD interface consists of an SPI bus that is connected between the FPGA and a CLCD connector
and an LCD touch screen.
The LCD Thin Film Technology (TFT) display panel is fitted to the CLCD connector and has 320x240
pixel resolution. The panel includes a 4-wire resistive touch screen and an STEMPE811 touch screen
controller that is connected to the FPGA over an I
2
C bus.
The following figure shows the board VGA and CLCD interfaces.
