02_setRGB565pixelsQuestionMark.cpp

/* File: 02_setRGB565pixelsQuestionMark.cpp
 * Author: Philippe Latu
 * Source: https://github.com/platu/libsensehat-cpp
 *
 * This example program illustrates the senseSetRGB565pixels() function that
 * prints all pixels at once.
 * One pixel colors are encoded in RGB565 format. This format fits into a 16
 * bit integer defined by the rgb565_pixel_t type.
 * All pixels are stored in a 8x8 array of rgb565_pixel_t elements.
 * The complete pixel map is defined by the rgb565_pixels_t type.
 *
 * Function prototype:
 *
 * void senseSetRGB565pixels(rgb565_pixels_t );
 *             all pixels map -^
 *
 * The program prints a red question mark on a white background.
