An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...

When an air quality display project needed a display, [Inderpreet] looked into small character-based LCDs. [Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy ...

You only really need two data wires to transfer a ton of data. Standards like UART, USB2, I2C, SPI, PS/2, CAN, RS232, SWD (an interface to program MCUs), RS485, DMX, and many othe ...

Many microcontroller-based projects use an LCD panel and buttons for their user interface. These generally swallow up a large number of the port pins on the microcontroller, making them unavailable ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

This project simplifies the use of KS0108-based monochrome graphic LCD modules. These displays have an 8-bit parallel interface and control signals that would need at least 14 port pins of your host ...
