* | File      	:   DEV_Config.h
* | Author      :   Waveshare team
* | Function    :   Hardware underlying interface
* | Info        :
*                Used to shield the underlying layers of each master
*                and enhance portability
*----------------
* |	This version:   V2.0
* | 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_GPIOI_write(_pin, _value)
*   #define DEV_Digital_Read(_pin) bcm2835_GPIOI_lev(_pin)
*   #define DEV_SPI_WriteByte(__value) bcm2835_spi_transfer(__value)
