Hi,

to handle the DVI output port, you should add the xps_tft peripheral. You can found usefull information here : http://www.xilinx.com/products/boards/ml501/ml501_11.1_1/docs/ml501_bsb_std_ip_addition.pdf

The xps_tft comes with api functions and also example routines to write messages to the output; you'll find these in the appropriate directory in the directory sw\XilinxProcessorIPLib\drivers\tft_v2_00_a\examples under your EDK installation

Hi,

for the LCD you can use a xps_gpio. In the reference design http://www.xilinx.com/products/boards/ml501/ml501_11.1_1/files/ml501_bsb_std_ip.zip

you can find how to do this. In the sw\standalone\lib\src\lcd_char directory there's also a lcd.c file with simple API to write data to the display. Regards
