Get started

Install the ESP32 SDK

http://esp-idf.readthedocs.io/en/latest/

Note:

This project tries to be compatible with the ESP-IDF v4.0. Instructions here are given for the v4.x toolchain using idf.py, but it is easy to translate to make. For example instead of running idf.py menuconfig, just run make menuconfig.

Build this repository standalone and run the demo.

Try this first to make sure your hardware is supported, wired and configured properly.

  1. Get this project: git clone --recurse-submodules https://github.com/wireless-tag-cn/lv_port_esp32.git

  2. From its root run idf.py menuconfig

  3. Select your display kit or board and other options - see config options

  4. For monochrome displays we suggest enabling the unscii 8 font (Component config -> LVGL configuration -> FONT USAGE) and the MONO theme (Component config -> LVGL configuration -> THEME USAGE).

  5. Store your project configuration.

  6. For monochrome displays edit the lv_conf.h file available on the components/lvgl directory to look like follows:

#define LV_THEME_DEFAULT_INIT               lv_theme_mono_init
#define LV_THEME_DEFAULT_COLOR_PRIMARY      LV_COLOR_BLACK
#define LV_THEME_DEFAULT_COLOR_SECONDARY    LV_COLOR_WHITE
#define LV_THEME_DEFAULT_FLAG               0
#define LV_THEME_DEFAULT_FONT_SMALL         &lv_font_unscii_8
#define LV_THEME_DEFAULT_FONT_NORMAL        &lv_font_unscii_8
#define LV_THEME_DEFAULT_FONT_SUBTITLE      &lv_font_unscii_8
#define LV_THEME_DEFAULT_FONT_TITLE         &lv_font_unscii_8

  1. idf.py build

  2. idf.py -p (YOUR PORT) flash
