First, connect the Waveshare e-Paper module to Ameba RTL8722DM_MINI shown in the wiring diagram below:
The programming of the Ameba RTL8722DM can be done using Arduino IDE which makes it very easy to write code and upload code to the Ameba Board.
Firstly, you need to prepare a picture/photo in the format of 296×128 pixels. We can easily find a photo resizing tool online, for example, the Online Image Resizer. Following the instructions on the website, then download the generated image in JPG format. Secondly, we use the Image2LCD tool to transfer the downloaded 296×128 image into hexadecimal codes. You can visit this YouTube link to get detailed instructions.
To open the example code in Arduino IDE, Open "File" -> "Examples" -> "AmebaEink" -> "EinkDisplayText"
Upload the code to the board and press the Reset button after the uploading is done. You will find these texts displayed on the board:
