算法

1. 判断一个数是否为奇数

if((data & 0x1U) == 0x1U){
	//为奇数
}

2. 如何将UINT16数据按位取出

#define BIT_MASK 0x1
void APPL_OutputMapping(UINT16 *pData)
{
//code...
	  UINT16 data = 0U;
	  (LEDS0x7000.LED1) = data & BIT_MASK;
      data = data >> 1U;//
      (LEDS0x7000.LED2) = data & BIT_MASK;//此时data 的最后一位已经变成第2位数据
      data = data >> 1U;
      (LEDS0x7000.LED3) = data & BIT_MASK;
      data = data >> 1U;
      (LEDS0x7000.LED4) = data & BIT_MASK;
      data = data >> 1U;
      (LEDS0x7000.LED5) = data & BIT_MASK;
      data = data >> 1U;
      (LEDS0x7000.LED6) = data & BIT_MASK;
      data = data >> 1U;
      (LEDS0x7000.LED7) = data & BIT_MASK;
      data = data >> 1U;
      (LEDS0x7000.LED8) = data & BIT_MASK;

//code...

}
