-# Example for lv_arduino using a slider
-
-This example has the screen set to 320x480 (ILI9488), change this by altering the following lines in the main ino file:
-
-```C
-int screenWidth = 480;
-int screenHeight = 320;
-```
-
-## Backlight
-
-Change pin 32 to your preferred backlight pin using a PNP transistor (2N3906) or remove the following code and connect directly to +ve:
-
-```C
-  ledcSetup(10, 5000/*freq*/, 10 /*resolution*/);
-  ledcAttachPin(32, 10);
-  analogReadResolution(10);
-  ledcWrite(10,768);
-```
-
-## Theme selection
-
-Change the following to change the theme:
-
-```C
-  lv_theme_t * th = lv_theme_night_init(210, NULL);     //Set a HUE value and a Font for the Night Theme
-  lv_theme_set_current(th);
-```
-
-## Calibration
-
-This is using the bodmer tft_espi driver for touch. To correctly set the calibration load the calibration sketch and replace the following with your values:
-
-```C
-uint16_t calData[5] = { 275, 3620, 264, 3532, 1 };
-```
-
-## Screen rotation
-
-Check the following if you need to alter your screen rotation:
-
-```C
-  tft.setRotation(3);
-```

-# LVGL Arduino examples
-
-LVGL can be installed via Arduino IDE Library Manager or as an .ZIP library.
-It will install [lv_exmaples](https://github.com/lvgl/lv_examples) which contains a lot of examples and demos to try LVGL.
-
-## Example
-
-There are simple examples which use the [TFT_eSPI](https://github.com/Bodmer/TFT_eSPI) library as a TFT driver to simplify testing. 
-To get all this to work you have to setup TFT_eSPI to work with your TFT display type via editing the `User_Setup.h` file in TFT_eSPI library folder, or by selecting your own configurtion in the `User_Setup_Select.h` file in TFT_eSPI library folder.
-
-LVGL library has its own configuration file called `lv_conf.h`. When LVGL is installed to followings needs to be done to configure it:
-1. Go to directory of the installed Arduno libraries
-2. Go to `lvgl` and copy `lv_conf_template.h` as `lv_conf.h` next to the `src` folder.
-3. Open `lv_conf.h` and change the first `#if 0` to `#if 1`
-4. Set the resolution of your display in `LV_HOR_RES_MAX` and `LV_VER_RES_MAX`
-5. Set the color depth of you display in `LV_COLOR_DEPTH`
-6. Set `LV_TICK_CUSTOM 1`
-
-## Debugging
-
-In case of trouble there are debug informations inside LVGL. In the `ESP32_TFT_eSPI` example there is `my_print` method, which allow to send this debug informations to the serial interface. To enable this feature you have to edit `lv_conf.h` file and enable logging in section `log settings`:
-
-```c
-/*Log settings*/
-#define USE_LV_LOG      1   /*Enable/disable the log module*/
-#if LV_USE_LOG
-/* How important log should be added:
- * LV_LOG_LEVEL_TRACE       A lot of logs to give detailed information
- * LV_LOG_LEVEL_INFO        Log important events
- * LV_LOG_LEVEL_WARN        Log if something unwanted happened but didn't cause a problem
- * LV_LOG_LEVEL_ERROR       Only critical issue, when the system may fail
- * LV_LOG_LEVEL_NONE        Do not log anything
- */
-#  define LV_LOG_LEVEL    LV_LOG_LEVEL_WARN
-```
-
-After enabling log module and setting LV_LOG_LEVEL accordingly the output log is sent to the `Serial` port @ 115200 Bd.
