* | File : EPD_1in54b.c
|
||||
* | Author : Waveshare team
|
||||
* | Function : Electronic paper driver
|
||||
* | Info :
|
||||
*----------------
|
||||
* | This version: V2.0
|
||||
* | Date : 2018-10-30
|
||||
* | Info :
|
||||
* 1.Remove:ImageBuff[EPD_HEIGHT * EPD_WIDTH / 8]
|
||||
* 2.Change:EPD_Display(UBYTE *Image)
|
||||
* Need to pass parameters: pointer to cached data
|
||||
* 3.Change:
|
||||
* EPD_RST -> EPD_RST_PIN
|
||||
* EPD_DC -> EPD_DC_PIN
|
||||
* EPD_CS -> EPD_CS_PIN
|
||||
* EPD_BUSY -> EPD_BUSY_PIN
