Character LCD Modules


  • Implements the industry-standard Hitachi HD44780 LCD display driver chip protocol through the GPIO pins, I2C, and SPI interfaces.
  • Supports horizontal and vertical bar graphs.

General Description

The most commonly used Character LCD modules are based on the Hitachi HD44780 controller or others that are compatible with HD44580. The standard interface of the Character LCD module is parallel I/O pins, there are some devices in the markets that can convert I2C or SPI interface to the parallel ports. The Character LCD can be configured in 8-bit or 4-bit interface mode in which 8 data pins and 4 data pins are used respectively this feature allows efficient use of the digital I/O pins of the microcontroller.
