1.54inch e-Paper Module (B)

Introduction
Note: As the raw panel requires a driver board, we recommend you to buy the HAT or buy a driver board for use, or you need to make the driver board by yourself. And this instruction is based on the version with PCB or driver board.
200x200, 1.54inch E-Ink display module, three-color, SPI interface

Display a Frame (DisplayFrame)
DisplayFrame is used to send a frame to module, and the screen will refresh and display it.
Process: Send command data start transmission 1 -> Send data of dark area -> Send command data start transmission 2 -> Send data of red area -> Refresh the screen. Note:
- One frame consist of images of black area and red area, so we need to send two images for displaying one frame,
- The image of black part: 2 bits = 1 pixel, doesn’t support Gray scale (Can only display black and white). 00b stand for black pixel, and 11b stand for white.
For example:
0xC3:4 pixels □■■□ 0x00:4 pixels ■■■■ 0xFF:4 pixels □□□□ 0x66:The state of pixels is uncertain
- The image of red area: 1 bit = 1 pixel, doesn’t support Gray scale (Can only display red and white). The pixel is white if Bit is set, and it is red on the contrary.
For example:
0xC3:8 pixels □□■■■■□□ 0x00:8 pixels ■■■■■■■■ 0xFF:8 pixels □□□□□□□□ 0x66:8 pixels ■□□■■□□■
- This module doesn’t support partial refresh.
- The refresh rate of this module is slow, and it will flicker for several times during refreshing (about 8s). Please be patient.

When store three-color e-Paper, please refresh it to white, and keep the screen upward. Note that you need to update it at least every three months.
