Examples for LittlevGL applications(mock-up).

To link LittlevGL (lvgl) and lv_examples with ESP-IDF you need to add a component.mk file to each directory.
Espressif recommends to add third party software into a directory named components, so lvgl and lv_examples directories are located in a directory named components.
Next to this README file you find two component.mk template files:
- lvgl_component.mk
- lv_example_component.mk
Rename lvgl_component.mk to component.mk and move it to the lvgl directory, then rename lv_example_component.mk to component.mk and move it to the lv_examples directory, remember lvgl and lv_examples directories are located into the components directory.
2.8" TFT LCD Touch Screen (ILI9341 Driver)
| ESP32 | LCD |
|---|---|
| VOUT | VCC |
| GND | GND |
| IO5 | CS |

For ILI9341 VSPI is used, modify the pin configuration in components/drv/disp_spi.h to:
#define DISP_SPI_MOSI 23
#define DISP_SPI_CLK 18
#define DISP_SPI_CS 5and components/drv/ili9341.h to:
#define ILI9341_DC 17
#define ILI9341_RST 16
#define ILI9341_BCKL 4 //dummy (NC)Modify the configuration in components/drv/ili9341.c to:
#if ILI9341_INVERT_DISPLAY
uint8_t data[] = {0xF8};and components/drv/ili9341.h to:
#define ILI9341_INVERT_DISPLAY 1- Go to the project's directory:
cd esp-idf-littlevgl-sample - Build the project:
make - Upload the application to your board:
make flash
- Connect a 10 uF electrolytic capacitor between the EN pin and GND. : https://randomnerdtutorials.com/solved-failed-to-connect-to-esp32-timed-out-waiting-for-packet-header/
