|
|
* LVGL: https://github.com/lvgl/lvgl.git

|
||
|
|
*
|
||
|
|
* LVGL Configuration file:
|
||
|
|
* Copy your_arduino_path/libraries/lvgl/lv_conf_template.h
|
||
|
|
* to your_arduino_path/libraries/lv_conf.h
|
||
|
|
*
|

|
|
* In lv_conf.h around line 15, enable config file:
|
||
|
|
* #if 1 // Set it to "1" to enable content
|
||
|
|
*
|

|
|
* Then find and set:
