Introduction As we all know, LCD and LED segment display had greatly enriched human-computer interactions. But a connection with any controller usually requires numerous IO port lines, which is not only a big problem for controllers with limited peripheral interfaces but also poses restrictions on other functions the controller has. In order to solve this problem, we develop LCD2004 Module. This module carries I2C interface and is easy to use. Specification Interface: I2C I2C address: 0x27 Operating voltage: +5V Size: 27.7mm×42.6mm Contrast control: through potentiometer. This module carries I2C interface, so we need to comply with I2C protocol in usage and corresponding head files must be included and added into the library.
