LCD / MICROCONTROLLER MODULE
The DLP-MAV-LCD1 combines a 2x16-character backlit LCD display with a TI MSP430
microcontroller to form a MAVRK-supported display module. The MSP430 is preprogrammed with
basic functionality for driving the LCD display via either the MAVRK platform or a simple, 5-pin TTL
serial interface.
FEATURES:
•
Simple ASCII Command Set
•
Requires 3.0-3.3V Supply
•
LED
Backlight
•
5-Switch Joystick (Left, Right, Up, Down and Select)
•
Can Be Used Standalone or with the MAVRK Platform
1.0 GENERAL DESCRIPTION
The DLP-MAV-LCD1 provides the MAVRK platform with a means of displaying data that does
not
require a connected host PC.
To send data from the host processor on the MAVRK platform via the 2-wire TTL serial interface, the
host firmware sends the data to be displayed using the format described below in Section 3.
When the 5-switch joystick is operated, the DLP-MAV-LCD1 issues switch closure information to the
host processor using the MAVRK platform protocol. This protocol consists of a printable ASCII format
using a synchronization character “^”,
and a termination character
“~”. (This protocol is further
described in Section 3.)
The DLP-MAV-LCD1 is ready to accept commands immediately upon power up. (Initial baud rate and
serial parameters are outlined in Section 3.)
