This article offers a step-by-step guide on performing a grayscale test using the Arduino IDE on an ESP32 Ink Screen. It includes hardware and software requirements, library installation, and sample code instructions to achieve impressive display results.
Hardware Preparation
- ESP32 Ink Screen 4.7" ×1
Software Preparation
- Arduino IDE
- Download and install the EPD47 Library. (About how to install the library?)
Other Preparation Work
Install the Arduino IDE development environment for ESP32
Sample Code
Open the example in File>Examples>EPD47>grayscale_test of Arduino IDE.
Result
Upload the program to the E-ink screen, the E-ink screen will display as the following picture.
