还是用单片机吧！<BR>这个我也考虑过，液晶的控制需要延时，但是硬件实现延时很难的。要么就是用vhdl写个单片机程序嵌到里面，再用单片机控制，这样好一点。哈哈<BR><BR></TD></TR></TBODY></TABLE>

是啊，怎么说延时困难呢<BR>吴明诗的程序写的很好啊，看了之后才感觉用它控制很容易。最终的目的是用它控制一个彩色320×240的sharp的lcd，不知道谁有彩色液晶控制方面的资料，谢谢了<BR><BR></TD></TR></TBODY></TABLE>

用的着这么多状态吗？怎么办啊<BR>唉，那个用fpga控制lcd的程序我参考吴明诗的，编的还是很复杂，如果用状态机，每次有个信号变化都要一个状态，这样编下来不是要几百个状态吗，感觉还是没掌握方法。各位指点一下小弟啊。<BR>com:process(clk)<BR>begin<BR>if
