Shields Code Examples

• How do utilize development board shields?

/* Project name:
 *   How do utilize development board shields?
 * Copyright:
 *   (c) MIKROE, 2024.
 * Description:
 *   - Example is meant for demonstrating Board Support Package
 *     functionality using mikroSDK 2.0.
 * Library dependencies?
 *   - Make sure `Driver.GPIO.Out` and `Board` libraries are enabled
 *      NECTO's Library Manager to ensure a successful build.
 * How to test this code example?
 *   - Make sure to create `LVGL Designer` type of a project within NECTO.
 *   - Navigate to NECTO's [Planet Debug](https://www.mikroe.com/planet-debug)
 *     feature, connect to one of the following
 *     [dev boards](https://github.com/MikroElektronika/mikrosdk_v2/tree/master/bsp/board/include/shields),
 *     flash the code, and freely test all the other preprocessor directives
 *     from `shield.h` header file.
