Application: This sample code is based on the SPI and GPIO of ML51 to realize the electronic paper module that controls the micro-snow electronics. 2.9 inch e-Paper Module (B).
BSP Version: ML51 BSP Keil C51 V1.0.0
Hardware: NuTiny-SDK-ML51 V1.1
Electronic paper is a reflective display based on Electro-Phoretic Display (EPD) device. The principle of display is that the charged ions move in a transparent or colored liquid with an applied electric field, which is turned or flowed to brighten or darken the pixels, and can be fabricated on a glass, metal or plastic substrate.
Advantages of electrophoresis technology include low energy consumption, reflective display with good effects under the sunlight or in dark environments and the low power consumption when changing images.
