 * @brief       Example showing how to read the onboard temperature
 *              sensor on Inkplate 5V2 and display the value using LVGL.
 *
 * For info on Inkplate 5V2:
 * https://soldered.com/documentation/inkplate/5v2/overview/
 *
 * NOTE:
 *   Inkplate 5V2 ima isti API za temperaturu kao i ostale Inkplate modele,
 *   tako da se samo mijenja board selection i rezolucija se automatski skalira kroz LVGL.
