改写DSP281x_Adc.h,得到2种访问方式,不破坏原TI之习惯

struct ADC_REGS {
union ADCTRL1_REG ADCTRL1; // ADC Control 1
union ADCTRL2_REG ADCTRL2; // ADC Control 2

应用例如:
for (int i = 0; i < sizeof(Result); i ++)
{
Result[i] = 0;
}
for (int i = 0; i < 16; i ++)
{
AdcRegs.ADCRESULT[i] = 0;
}
AdcRegs.ADCRESULT[0] = 0;
AdcRegs.ADCRESULT0 = 0;
AdcRegs.ADCRESULT[1] = 0;
AdcRegs.ADCRESULT1 = 0;

此思路可在其他类型一致连续的结构中都可利用~~~
例如：
在DSP281x_ECan.h中

struct ECAN_MBOXES {
struct MBOX MBOX0;
//..........................
struct MBOX MBOX31;
};

改为:
struct ECAN_MBOXES {
struct MBOX MBOXS[32];
};

#define MBOX0 MBOXS[0]
//.......................
#define MBOX31 MBOXS[31]

在DSP281x_SysCtrl.h中
/* Password locations */
struct CSM_PWL {
Uint16 PSWD0; // PSWD bits 15-0
Uint16 PSWD1; // PSWD bits 31-16
Uint16 PSWD2; // PSWD bits 47-32
Uint16 PSWD3; // PSWD bits 63-48
Uint16 PSWD4; // PSWD bits 79-64
Uint16 PSWD5; // PSWD bits 95-80
Uint16 PSWD6; // PSWD bits 111-96
Uint16 PSWD7; // PSWD bits 127-112
};

可改为:
/* Password locations */
struct CSM_PWL {
Uint16 PSWD[8]; // PSWD bits 15-0
};

#define PSWD0 PSWD[0]
//...................
#define PSWD7 PSWD[7]

/* CSM Register File */
struct CSM_REGS {
Uint16 KEY0; // KEY reg bits 15-0
Uint16 KEY1; // KEY reg bits 31-16
Uint16 KEY2; // KEY reg bits 47-32
Uint16 KEY3; // KEY reg bits 63-48
Uint16 KEY4; // KEY reg bits 79-64
Uint16 KEY5; // KEY reg bits 95-80
Uint16 KEY6; // KEY reg bits 111-96
Uint16 KEY7; // KEY reg bits 127-112
Uint16 rsvd1; // reserved
Uint16 rsvd2; // reserved
Uint16 rsvd3; // reserved
Uint16 rsvd4; // reserved
Uint16 rsvd5; // reserved
Uint16 rsvd6; // reserved
Uint16 rsvd7; // reserved
union CSMSCR_REG CSMSCR; // CSM Status & Control register
};

改为:
struct CSM_REGS {
Uint16 KEY[8];
//.................................
