API for the JHD1313M1 I2C controller for HD44780-based displays with an RGB backlight, such as a Grove RGB I2C LCD display. More...

Detailed Description

ID: jhd1313m1
Name: JHD1313M1 Display
Other Names: Grove RGB LCD
Category: display
Manufacturer: seeed adafruit sparkfun

Connection: i2c
Kit: gsk

JHD1313M1 has two I2C addreses: one belongs to a controller, very similar to the upm::Lcm1602 LCD driver, that controls the HD44780-based display, and the other controls only the backlight. This module was tested with the Seeed Grove LCD RGB Backlight v2.0 display that requires 5V to operate.

    // 0x62 RGB_ADDRESS, 0x3E LCD_ADDRESS
    upm::Jhd1313m1 *lcd = new upm::Jhd1313m1(0, 0x3E, 0x62);
    lcd->setCursor(0,0);
    lcd->write("Hello World");
    lcd->setCursor(1,2);
    lcd->write("Hello World");
    printf("Sleeping for 5 seconds\n");
    sleep(5);
    delete lcd;
