Until recently, microcontroller-based systems using a liquid crystal display (LCD) output device required a separate driver device. Now, Microchip has announced its new PIC16F946 microcontroller, ...

In remote control system, radio frequency modules are used for transmitting and receiving logic signals. A (16×2) LCD display is mounted on remote controller to check the user command.

The PIC24FJ128GC010 family includes an integrated LCD display driver that provides the ability to drive up to 472 segments with information-rich user displays that include scrolling alphanumeric ...

You can interface this type of display to a microcontroller using one or two output pins. The one-pin MCU interface employs a pulse-width-encoded output per segment.

A bar-graph display provides an easily interpreted graphical indicator that allows comparison with its full-scale value, but a conventional microcontroller-based design uses at least one eight-line ...

The algorithm in this microcontroller design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is changing ...

From there, and with the knowledge that most POS terminals use RS232 to communicate, he was able to zero in on the Rx and Tx pins on the on-board microcontroller and interface them with an Arduino.

We’d guess that a serial-to-Bluetooth converter could also be made to function, with a bit of work. The protocol is trivial too, meaning that almost any microcontroller could make use of it.
