<br>
== Description ==
When doing DIY experiments, we often need to use the display. The Keyestudio electronic ink screen module has a 2.13-inch display with a black and white color and a resolution of 250*122. <br>
The module dynamically displays the pattern via SPI communication. <br>
There are 2 slide switches on the back. The P1 slide switch is for adjusting the display brightness. Sliding to “0.47” position, the display is brighter; sliding to “3” position, the display is darker. <br>
The P2 DIP switch is used to adjust the power supply voltage. Sliding to“5VIN” position, the power supply voltage is 5V; sliding to “3.3VIN”, the power supply voltage is 3.3V.<br>
The module comes with two positioning holes with a diameter of 3mm, easy to fix it on other devices .<br>
For your convenience, we also provide detailed methods for using the display module and the arduino microcontroller.<br>
<br>
Special Note: When testing, we use the IDE software 1.8.9 version; if you use other versions of the IDE, source code may be incompatible.<br>

<br>
== Setting the Code ==
1)Before settings, we need to install Image2Lcd software. After installation, register with the registration code. <br>
2)Use the drawing software to draw the pattern you need, export set to black and white, and the pixel is set to 250*122.<br>
3)Open the modulo software and set as the following picture shown.<br>

4)Click Open, select the pattern you exported, as shown below.<br>
<br>

Normal display (black on white), then tick "color reversal" ; negative display (white on black ) no need to tick.
5)Click Save, generate the corresponding C language file. As shown below.<br>
br>

== Test Result ==
Done uploading the source code, the E-ink Screen will display patterns. As shown below. (at this moment, slide switch 1 to “0.47”, slide switch 2 to “5VIN”)
