E-Paper display 1.54" 200x200 dots (Mikroe)

Summary

This project aims to show the hardware driver that is used to interface with the E-Paper display 1,54" 200x200 dots driver from Mikroe via APIs of GSDK.

E-Paper display is based on Active Matrix Electrophoretic Display (AMEPD) technology and has an integrated pixel driver, which uses the SPI interface to communicate with the host MCU. E-Paper display has resolution of 200(V) X 200(H) pixels and an active display area of 27.6 X 27.6. The size of its square shaped pixels is 0.138mm x 0.138mm. The screen displays a clear and crisp graphics, and has an ultra-wide viewing range. Another key feature of the E-Ink technology is the extremely low power consumption, even when the display actively refresh its content.

Required Hardware

• EFR32xG24 Explorer Kit

• EINK CLICK - WITHOUT DISPLAY

• E-Paper display 1,54" 200x200 dots

Hardware Connection

eINK display needs an external adapter to interface with the EFR32xG24 Explorer Kit. The hardware connection is shown in the image below:

Setup

You can either create a project based on an example project or start with an empty example project.

Create a project based on an example project

1. From the Launcher Home, add the BRD2703A to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project with filter E-Paper.

2. Click Create button on the Third Party Hardware Drivers - E-Paper Display (Mikroe) example. Example project creation dialog pops up -> click Create and Finish and Project should be generated.

3. Build and flash this example to the board.

Start with an empty example project

1. Create an "Empty C Project" for the "EFR32xG24 Explorer Kit" using Simplicity Studio v5. Use the default project settings.

2. Copy the file app/example/mikroe_e_paper_154_inch/app.c into the project root folder (overwriting the existing file).

3. Install the software components:

   • Open the .slcp file in the project.

   • Select the SOFTWARE COMPONENTS tab.

   • Install the following components:

     • [Third Party Hardware Drivers] → [Display & LED] → [E-Paper display 1.54" 200x200 dots (Mikroe)]
     • [Third Party Hardware Drivers] → [Services] → [GLIB - OLED Graphics Library]

4. Build and flash this example to the board.

Note:

• Make sure that the SDK extension already be installed. If not please follow this documentation.

• Third-party drivers extension must be enabled for the project to install "E-Paper Display (Mikroe)" component.

How It Works

Testing

After setting up all the required components, flash the code to the Explorer Kit and you will see the result looks like below.
