比方说，让P1.18变为低电平

只需要

DIR118 = 1;//输出状态

P118 = 0; //P1.18设为低电平

SKYdai 发表于 2006-4-2 18:32:39

能不能出个S64的呢？

Gorgon_Meducer 发表于 2006-4-3 23:38:33

其实原理大家看得都很明白了哈，自己做嘛

tiger5 发表于 2006-5-30 08:18:19

好人...谢谢.

FlashNuk 发表于 2007-10-5 10:10:05

好东西啊，正是我需要的，谢谢傻孩子！

classv 发表于 2008-3-17 16:29:47

能不能整个直接和位同时好操作的
如: P1.DIR.BIT.B18 = 1;//输出状态 ==P1.DIR.BYTE=(1<<18);

liuzhijun 发表于 2008-3-21 21:14:11

谢谢！

shishi 发表于 2009-7-5 14:43:23

不够全

shishi 发表于 2009-7-6 22:14:58

不知道这个代码测试过没有，
            “比方说，让P1.18变为低电平
            只需要
            DIR118 = 1;//输出状态
            P118 = 0; //P1.18设为低电平”
中的P118 是映射到 IO1PIN寄存器，地址为：0xE0028010，这个是一个只读的吧，P118 = 0；行吗？有空我测一下试试

好东西顶起来

wukaka 发表于 2010-8-18 10:48:07

位域好东西

yywin 发表于 2010-10-29 21:32:58

IOxPIN是可读可写的,推荐用IOxSET、IOxCLR置1，置0。

qqsdlpz 发表于 2010-11-29 10:16:15

位域滥用。。。

sokou 发表于 2011-3-29 22:11:39

谢谢！

Gorgon_Meducer 发表于 2011-3-30 09:53:51

to 【17楼】 qqsdlpz
对当时我一个大二的学生来说，不用又怎知滥呢……
