8-bit parallel interface or 4-bit parallel interfaceġ6×2 LCD Pinout and Pin Description PCF8574 I/O Expender.Built-in character RAM for up to 8 user-defined characters.Supports alphanumeric characters and symbols.16×2 character display (16 columns x 2 rows).The HD44780 is widely used in various applications, such as industrial control systems, consumer electronics, and automotive displays. This LCD controller communicates with microcontrollers through an 8-bit parallel interface or a 4-bit parallel interface, depending on the mode selected. The HD44780 supports up to 32 characters (16 columns x 2 rows) and offers various features such as character generation, display data RAM, and display on/off control. This controller is widely used due to its low power consumption, ease of use, and reliability. The Hitachi HD44780 is a popular LCD controller used in many 16×2 character LCD displays. We will use the STM32CubeIDE software to write the code, which provides a comprehensive set of tools for developing, debugging, and deploying STM32-based embedded applications. The LCD module we will use is a Hitachi HD44780 controller based 16×2 LCD module with a PCF8574 I2C interface. In this tutorial, we will discuss how to interface an STM32 microcontroller with an I2C LCD module. I2C is a popular choice for interfacing LCD modules with microcontrollers because it requires only two pins, simplifying the wiring and reducing the number of GPIO pins needed. I2C is a communication protocol that allows multiple devices to communicate with each other using just two wires: a clock line (SCL) and a data line (SDA). However, traditional methods of interfacing LCDs with microcontrollers can be complex, requiring many GPIO pins and complex wiring. LCDs provide an easy-to-read visual output that can display various types of information, such as sensor readings, status messages, and user inputs. Interfacing LCD modules with microcontrollers is a common requirement in many embedded applications.
