還是用單片機吧！<BR>這個我也考慮過，液晶的控制需要延時，但是硬件實現延時很難的。要么就是用vhdl寫個單片機程序嵌到里面，再用單片機控制，這樣好一點。哈哈<BR><BR></TD></TR></TBODY></TABLE>

是啊，怎么說延時困難呢<BR>吳明詩的程序寫的很好啊，看了之后才感覺用它控制很容易。最終的目的是用它控制一個彩色320×240的sharp的lcd，不知道誰有彩色液晶控制方面的資料，謝謝了<BR><BR></TD></TR></TBODY></TABLE>

用的著這么多狀態嗎？怎么辦啊<BR>唉，那個用fpga控制lcd的程序我參考吳明詩的，編的還是很復雜，如果用狀態機，每次有個信號變化都要一個狀態，這樣編下來不是要幾百個狀態嗎，感覺還是沒掌握方法。各位指點一下小弟啊。<BR>com:process(clk)<BR>begin<BR>if
