一个AD9851的驱动。用的并行时序。 现在把程序和电路图发上来，大家帮帮我看看问题出在那里。谢谢了。 要是有做成功的能共享一下电路和程序感激！ main.c -An AD9851 driver. Timing used in parallel. Now that the procedures and schematics hair up, everyone help me to see the problem there. Thank you. If success has to do to share about the circuit and procedures grateful! main.c

jpxs程序功能可以实现，但本人认为算法比较混乱，待以后作出好的算法。 键盘用p2.2--p2.7 码显示用p3.6,p3.7-jpxs program features can be achieved, but I think that the algorithm a bit confusing, to be later made a good algorithm. P2.2 p2.7 code using the keyboard display with p3.6, p3.7
