| Serial LCD and Keypad Controller |
Serial LCD and Keypad Controller provides a serial communication interface for LCD and
your microcontroller or PC. The serial controller takes care of all commands between LCD and
your microcontroller and uses only two lines for communications.
The controller supports all standard character LCD from 8x1 to 20x4 format.
The simple command structure allows text and bar graphs to be displayed on the screen.
Provision is made for up to 8 user-defined characters. The module includes also the 4x4 matrix
keypad control.
The LDC backlight and contrast may be adjusted under program control to compensate for
differing lighting conditions and viewing angles.
The controller supports IR Remote Control.
The module supports 2 interfaces:
