【求助位带操作】 位带操作的地址放入数组，实现while轮训位带操作的地址

[shiguojie19892]

在做一个17芯线缆通断检测的程序，利用10个OUT口和10个IN口，依次控制OUT输出高低电平，希望把OUT口位带地址放进数组里面，请教应该怎么实现？对指针和位带操作的指针放入数组的操作不熟悉，请指教。

代码如下：
*****以下头文件：
#define LINE_NUM_SUM 17

#define OUT0 PAout(0)
#define OUT1 PBout(1)
#define OUT2 PBout(2)
#define OUT3 PBout(3)
#define OUT4 PBout(4)
#define OUT5 PAout(5)
#define OUT6 PBout(6)
#define OUT7 PBout(7)
#define OUT8 PBout(8)
#define OUT9 PBout(9)
#define OUT10 PBout(10)
#define OUT11 PBout(11)
#define OUT12 PBout(12)
#define OUT13 PBout(13)
#define OUT14 PBout(14)
#define OUT15 PBout(15)
#define OUT16 PAout(6)
#define OUT17 PAout(7)

**********以下C文件

void checkInit()
{
u8 i = 0;
GPIO_InitTypeDef GPIO_Initure;

__HAL_RCC_GPIOA_CLK_ENABLE(); //开启GPIOB时钟
__HAL_RCC_GPIOB_CLK_ENABLE(); //开启GPIOE时钟
__HAL_RCC_GPIOC_CLK_ENABLE(); //开启GPIOE时钟

//OUT 初始化
GPIO_Initure.Pin=GPIO_PIN_0|GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7; //0 5 6 7
GPIO_Initure.Mode=GPIO_MODE_OUTPUT_PP; //推挽输出
GPIO_Initure.Pull=GPIO_PULLDOWN; //下拉
GPIO_Initure.Speed=GPIO_SPEED_FREQ_HIGH; //高速
HAL_GPIO_Init(GPIOA,&GPIO_Initure); //GPIOA OUT

GPIO_Initure.Pin=GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3|GPIO_PIN_4; //1 2 3 4
GPIO_Initure.Pin|=GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8|GPIO_PIN_9; //6 7 8 9
GPIO_Initure.Pin|=GPIO_PIN_10|GPIO_PIN_11|GPIO_PIN_12|GPIO_PIN_13; //10 11 12 13
GPIO_Initure.Pin|=GPIO_PIN_14|GPIO_PIN_15; //14 15
HAL_GPIO_Init(GPIOB,&GPIO_Initure); //GPIOB OUT

//测试OUT能否循环输出
while(i < LINE_NUM_SUM)
{
if(OUTThis[i])
OUTThis[i] = 0;
else
OUTThis[i] = 1;

delay_ms(1000);
}
}

为什么要这么麻烦？ 用一个变量轮询生成数据，直接写入ODR不是更直接？ //测试OUT能否循环输出

[shiguojie19892]

ODR并不是相邻的，怎么轮训，需要把每个地址编入一个地方组队吧？ 我现在就是把设置好的GPIO编入数组，然后就可以轮训了，已经实现了OUT，但是IN发现不对呀，IN的取数地址这样不对。

for(i = 0;i < LINE_NUM_SUM;i++)
	{
		info_err[i].line_num = i;				//写入当前线号
		*OUTThis[i] = 1;						//设置线路高电平*****！！！！！注意这里，这个OUT口可以这样操作
		
		delay_us(1);
		
		//判断是否导通
		if(1 == *INThis[i])						//检测线路导通
		{
			info_err[i].open_err |= 0;			//导通，不报错
		}
		else
		{
			info_err[i].open_err |= 1;			//不通，报错
		}
		
		//判断与其他线路是否短路
		j = i+1;
		while(j < LINE_NUM_SUM)
		{
			if(1 == *INThis[j])//这里判断输入，好像不对！！！！！！！！！！！！！！！！！！！！！
			{
				info_err[i].short_err |= 1;
				x = PBin(15);
				break;
			}
			j++;
		}
		
		info_err[i].short_err |= 0;
		*OUTThis[i] = 0;						//设置线路低电平		
	}

数组不支持bit类型，你想其他办法吧， 可以用整个端口移位

        while(j < LINE_NUM_SUM)
        {
            if(1 == (PA>>j))
            {
                info_err[i].short_err |= 1;
                x = PBin(15);
                break;
            }
            j++;
        }

利用数组指针和位带操作可以轮训GPIO口。
