... C communications 1.1 What to Expect From the GLK12232-25-WBL The GLK12232-25-WBL is designed as the display unit for an associated controller. The controller may be anything from a single board, special purpose micro-controller to a PC, depending on the application. This controller is responsible for what is displayed on the screen of the display. ...

... Connect the power connector, making sure that the +5V goes shown in the diagram. 5. Turn on the power: the LCD backlight should come on. 1.6 Trying Out the GLK12232-25-WBL The unit should be connected to power and the PC and backlight should be on. 1. Use the mogd.exe program to exercise some of the features of the display to ensure everything works properly experiment with typing text, run a PC terminal program, such as Hyperterm. Make sure it’ ...

... This chapter describes the various text-display commands in detail. 3.1 General Text is displayed on the display using fonts saved in its internal flash memory. The display is supplied with a 5x7 font installed. If this is suitable, there will be no need to install any other fonts. Matrix Orbital Figure 5: Clamping a Relay GLK12232-25-WBL 8 ...

... When auto scrolling is on, it causes the display to shift the entire display’s contents up to make room for a new line of text when the text reaches the scroll position defined by the "Set font metrics" command in the display memory (normally the bottom right character position - default value for the GLK12232-25-WBL is 64). ...

... Since this command involves consid- erable processing overhead, we strongly recommend the use of flow control, particularly if the command repeated frequently. This procedure is common for monitoring applications where there is a ’field’ on the display that is constantly being updated from, say, a temperature sensor. Matrix Orbital GLK12232-25-WBL 12 ...
Page 17
... Flow control is enabled or disabled by two commands. If flow control is enabled, the display will return an "almost full" message (0xFE) to the micro-controller when its internal buffer fills to a defined level, and an "almost empty" message (0xFF) when the buffer contents drop to a defined level.

... The display keypad interface processes the keypad row / column matrix into a serial (RS-232 or I data byte stream. Aside from this processing, the keypad has no effect on the display necessary to send keystrokes to the display, they must be routed through the micro-controller. Matrix Orbital GLK12232-25-WBL ...
Page 19
... NOTE The keypad connector must be wired with columns on one side and rows on the other side of the center of the connector. In situations where the keypad isn’t wired this way an adapter will need to be made, or the user should rewire the connector to meet this requirement.
