Get started

Prerequisites

• ESP-IDF v4 Framework.
• LVGL soucre copied in IDF

Note

This project tries to be compatible with both the ESP-IDF v3.x and v4.0, but using v4.0 is recommended. Instructions assume you are using the v4.x toolchain, otherwise use the make commands, e.g. instead of running idf.py menuconfig, run make menuconfig.

Build and run

1. Clone this project

2. Run idf.py menuconfig

3. Configure LVGL in Components config->LVGL Configuration. For monochrome displays use the mono theme and we suggest enabling the unscii 8 font.

4. Configure your display and/or touch controllers in Components config->LVGL TFT Display Configuration and Components config->LVGL TOUCH Configuration.

5. Store your project configuration.

6. Build the project with idf.py build

7. If the build don't throw any errors, flash the demo with idf.py -p (YOUR SERIAL PORT) flash (with make this is just make flash - in 3.x PORT is configured in menuconfig)
