如何创建端口引脚数组

我试图用一个索引数组访问连接到各种端口引脚的LED，但不能使它工作。其目的是对阵列进行索引并依次对每个LED进行光照。作为测试代码片段：定义了LeD1αLATB3α，定义了LeD2αLATC3/ /设置端口引脚作为输出，TrISB3＝0；γTrISA2＝0；BoOL LED（3）α属性（（α-SFRSH））＝{LeD1，LeD2，ReD3}；//TestDeld1＝1；/Works，LED灯/ /…LED（0）＝1；/ /不工作，LED不发光。W是否需要创建一个数组来访问端口引脚的组合——我可以看到这是如何在一个比特结构中，如下面的顺序对序列引脚进行的，但是不能计算出数组中的不同端口引脚。结构标记TabLabes {无符号LATB0-1；未签名的LATB1∶1；未签名的LATB3-1；未签名的LATB4-1；未签名的LATB5∶1；未签名的LATB6∶1；未签名的LATB7-1；未签名的LATB8-1；} LabbTes；外部易失性LabbButts LabbTysAtidTyTeX（（α-SFRSH））；谢谢。

    I am trying to access LEDs connected to various port pins using an indexed array, but can not get this to work. The aim is to index the array and light each LED in turn. As a test code snippet:

#define LED1 _LATB3
#define LED2 _LATA2
#define LED3 _LATC3

// Set port pins as outputs
_TRISB3 = 0;
_TRISA2 = 0;
_TRISC3 = 0;

bool LEDs[3] __attribute__((__sfr__)) = {LED1, LED2, LED3};

// Test
LED1 = 1;  // Works, LED lights

// but...
LEDs[0] = 1;  // Does not work, LED does not light

How does one go about creating an array to access a mix of port pins - I can see how this is done for sequential pins in a bit structure, like below, but can not figure out how to have different port pins in an array.

#define LATB LATB
extern volatile unsigned int LATB __attribute__((__sfr__));
typedef struct tagLATBBITS {
unsigned LATB0:1;
unsigned LATB1:1;
unsigned LATB2:1;
unsigned LATB3:1;
unsigned LATB4:1;
unsigned LATB5:1;
unsigned LATB6:1;
unsigned LATB7:1;
unsigned LATB8:1;
} LATBBITS;
extern volatile LATBBITS LATBbits __attribute__((__sfr__));

Thanks.
