The EE05 supports a variety of 24-Pin SPI ePaper displays, including but not limited to:

Software Overview​

Install Seeed GFX Library​

tip

This library has the same function as the TFT library and is not compatible with it. If you have installed the TFT library or other similar display libraries, please uninstall them first.

Download and install the Seeed GFX library from GitHub.

Scroll down and open this link.

Select your device type and it will generate some code. Copy those code and we will use them later.

tip

If you make the wrong choice, the screen will display nothing.

So please make sure you select the correct device or component type.

After downloading the library, go to Sketch -> Include Library -> Add .ZIP Library and select the downloaded library.

Getting Started​

Here, we use a 7.5-inch monochrome display as an example. The steps are identical for other supported screens; you simply need to select the appropriate screen size identifier in the driver.

Configure and burn the program​

Select the example shown in the figure

Create a new "driver.h" file and paste those code into it. The code should be like:

#define BOARD_SCREEN_COMBO 502 // 7.5 inch monochrome ePaper Screen (UC8179)
#define USE_XIAO_EPAPER_DISPLAY_BOARD_EE05

After that, go to Tools -> Board -> XIAO ESP32S3 and Tools -> Port -> Select the port your board is connected to.

Note that PSRAM must be enabled.

Then click Upload to upload the code. Now you will see the feedback in your ePaper screen! Following are the results of Bitmap examples.

Troubleshooting​

Q1: The screen does not display anything after uploading the code.

  • Check the FPC Cable: Ensure the ePaper FPC cable is inserted in the correct orientation and is securely locked in the connector.
  • Verify the Driver Configuration: Double-check driver.h to make sure the correct BOARD_SCREEN_COMBO is selected for your specific screen size.

Q2: The colors are inverted or the display shows abnormal patterns.

  • Select the Exact Model: Different screen sizes or IC revisions require specific driver configurations. Ensure the combo number perfectly matches your screen model.
  • Check Power Supply: For larger screens (like 7.5-inch), ensure your power source can provide adequate current during screen refresh.

Q3: The board doesn't power on when connected to a battery.

  • Hardware Switch: Verify that the hardware slide switch on the board is toggled to the ON position.
  • Battery Connection: Check the JST 2.0mm connector polarity to ensure it matches the board's design.
