I’d like someone to make a **Node** that will work with **20 x 4** and **RGB**  **LCD**  
and is **HD44780** compatiable. And will be **Serial** or **I2C** compatiable.

Hi! @teddy

XOD standard library has nodes to drive HD447780 based 20x4 displays.  
For parallel interface - [`text-lcd-parallel-20x4`](https://xod.io/libs/xod-dev/text-lcd/text-lcd-parallel-20x4/)  
For I2C interface - [`text-lcd-i2c-20x4`](https://xod.io/libs/xod-dev/text-lcd/text-lcd-i2c-20x4/)

What do you mean by “RGB LCD” and by “Serial interface for HD44780”?

Thanks for the info. These displays are available with RGB, that’s why they have 18 Pins, rather then the standard 16-Pins

You don’t need RGB pins to work with display logic. Use the `text-lcd-parallel-20x4` node. For the backlight, for R G and B colors, you can directly use `pwm-write` nodes.

I understand that. I’m saying someone should create a node with RGB Control

in one node. I’m sure others feel the same way.

However, I do see what your displaying below to accomplish this task.
