LCD displays are commonly supplied as a module with a built-in driver circuitry usually mounted on a PCB at the rear of the module. While this strengthen the module mechanically, it has some drawbacks such as it increases the thickness of the display module and raises the manufacturing cost. NXP semiconductors describes the Chip-On-Glass technology …
In this intractable we will learn how we can hook up an LCD based on the HD44780 chipset to the SPI bus and drive it with only 3 wires for less than $1. Although I will focus on the HD44780 alphanumeric display in this tutorial, the same principle will work pretty much the same for …
This is an Example of how you can use the Arduino to monitor various environmental parameters And display them on a LCD screen. Note: I Added a Real Time Clock!! To see the steps, added parts and Sketch I added new steps.. Arduino uno R3 or compatible …
I develop this MCP23017 Breakout Board to interface a 2×16 LCD display with any microcontroller using a standard I2C bus. Typical 2×16 displays needs at least 6 lines to work (when working in 4-byte mode); in some cases, this will be prohibited for some microcontrollers. With this board, you can control it with only two …
