System Overview
4.1.
General SLCD+ Controller
The SCLD acts as a "smart terminal" and is generally connected to a host processor that
implements the desired Graphical User Interface (GUI) by issuing commands to the
SLCD+ and processing button press responses from the SLCD+. In this manual, the term
"host" is used to describe the device connected to the SLCD+.
Please refer to the
SLCDx Software Reference Manual
for more detail.
4.2.
Overview - SLCD+ Evaluation Kits
The SCLD+ is available in an evaluation kit form, and also as a complete enclosed unit. In
the kit or enclosure, it comes pre-loaded with bitmaps and macros that implement a demo
if the unit is powered on with the communications port looped back transmit to receive.
This loopback is via external plug in the case of the enclosed unit, or via a jumper on the
"PowerCom" board in the case of the unenclosed kit.
The SLCD+ evaluation kit comes with hardware and firmware options loaded for the
specific panel supported by the kit. It also includes a two-port DB9 interface board that
makes it easier to connect to external host systems. One port can be used to download
bitmaps from a PC while the other connects to the "host" computer.
4.2.1. Getting Started
The SLCD+ kit as shipped contains a demo that allows you to verify its functionality. Plug
the supplied power supply into the barrel connector on the triangular shaped PowerCom 4
board. The display should light up and lead you through various touch-activated screens.
4.2.2. Connecting the kit to a PC
The kit should be connected to a PC so that the serial command interface can be
experimented with. This is a preliminary step before the unit is connected to the embedded
system that will control the display in the embedded system.
.
PLEASE NOTE: In order
to communicate over the serial port, the Demo jumper JP1 on the triangular
PowerCom4 board must be removed.
This jumper loops back transmit to receive on the
serial port and this is what tells the SLCD+ to run the demo.
