设置输出端口高低C [英] Set Output Port High Low C
问题描述
我使用MPLAB利用CCS编译器编译在C程序。
我想设置输出端口为高或低使用定义的端口。
#bit portOut1 = PORTC.0
所以,我想我的设置 portOut1
高或低。
我用了3种方式来做到这一点,但只是一个工作过。但我不是满意。
1:(?不行的,为什么)
portOut1 = output5.value;
2:(?不行的,为什么)
output_bit(portOut1,值);
3:(显然工作)
output_bit(pin_c0,值);
我不明白为什么第一和第二种方法是行不通的。
和我不想使用第三个,因为我不知道这脚做什么,除非我的评论,我不认为这是一个不错的方案做法。
任何人都知道一个办法做到这一点?或者有什么我做错了?
的#define portOut1 pin_c0
output_bit(portOut1,值)
I'm using MPLAB to compile a program in C using the CCS compiler.
I want to set an output port as high or low using defined ports.
#bit portOut1 = PORTC.0
So, I want to set my portOut1
high or low.
I had used 3 ways to do it, but just one had worked. But I'm not satisfied with that.
1: (Doesn't work, why?)
portOut1 = output5.value;
2: (Doesn't work, why?)
output_bit(portOut1,value);
3: (Obviously work)
output_bit(pin_c0, value);
I don't understand why the first and second way doesn't work.
And I don't want to use the third because I don't know what this pin do unless I comment, and I don't think that is a good program practice.
Anyone knows a way to do that? Or what I'm doing wrong?
#define portOut1 pin_c0
output_bit(portOut1, value)
