32 * @brief C++ API for Jhd1313m1 i2c controller for HD44780 based displays with
33 * an RGB backlight such as the Grove RGB i2c LCD display
35 * @snippet rgb-lcd.cxx Interesting
37 class Jhd1313m1 : public I2CLcd {
40 * Jhd1313m1 constructor
42 * @param bus i2c bus to use
43 * @param address the slave address the lcd is registered on
44 * @param address the slave address the rgb backlight is on
46 Jhd1313m1(int bus, int lcdAddress, int rgbAddress);
48 * Jhd1313m1 destructor
52 * Make the LCD scroll text
54 * @param direction, true is typical scrolling to the right
55 * @return Result of operation
57 mraa_result_t scroll (bool direction);
59 * Set the color of the backlight
61 * @param r 0-255 value for red
