 * Function List:
 * clearScreen() Remove content of display
 * setBrightness(uint8_t Bright) Brigthness of LED display (0 to 8)
 * drawBitmap(int8_t x, int8_t y, uint8_t Bitmap_Width, uint8_t *Bitmap) 
 * showClock(uint8_t hour, uint8_t minute, bool = PointOn)
 * drawStr(int16_t X_position, int8_t Y_position, const char *str)
 * showNum(float value,uint8_t = 3)
 * setColorIndex(bool Color_Number) 1 = normal mode, 0 = reverse colors mode
