  * | Date        :   2018-10-30
  * | Info        :
  * 1.add:
  *   UBYTE\UWORD\UDOUBLE
  * 2.Change:
  *   EPD_RST -> EPD_RST_PIN
  *   EPD_DC -> EPD_DC_PIN
  *   EPD_CS -> EPD_CS_PIN
  *   EPD_BUSY -> EPD_BUSY_PIN
  * 3.Remote:
  *   EPD_RST_1\EPD_RST_0
  *   EPD_DC_1\EPD_DC_0
  *   EPD_CS_1\EPD_CS_0
  *   EPD_BUSY_1\EPD_BUSY_0
  * 3.add:
  *   #define DEV_Digital_Write(_pin, _value) bcm2835_gpio_write(_pin, _value)
  *   #define DEV_Digital_Read(_pin) bcm2835_gpio_lev(_pin)
