Action

Sets the current font which can be used on some graphical displays.

 

 

Syntax

SETFONT font

 

 

Remarks

font

The name of the font that need to be used with LCDAT statements.

 

Since SED-based displays do not have their own font generator, you need to define your own fonts. You can create and modify your own fonts with the FontEditor Plugin.

 

SETFONT will set an internal used data pointer to the location in memory where you font is stored. The name you specify is the same name you use to define the font.

 

You need to include the used fonts with the $include directive:

 

$INCLUDE "font8x8.font"

 

The order of the font files is not important. The location in your source is however important.

The $INCLUDE statement will include binary data and this may not be accessed by the flow of your program.

When your program flow enters into font code, unpredictable results will occur.

So it is best to place the $INCLUDE files at the end of your program behind the END statement.

 

 

You need to include the glibSED library with :

$LIB "glibsed.lbx"

While original written for the SED1521, fonts are supported on a number of displays now including color displays.

$hwstack = 32                                               ' default use 32 for the hardware stack

$swstack = 10                                               ' default use 10 for the SW stack

$framesize = 40                                             ' default use 40 for the frame space

 

'I used a Staver to test

 

'some routines to control the display are in the glcdSED.lib file

'IMPORTANT : since the SED1520 uses 2 chips, the columns are split into 2 of 60.

'This means that data after column 60 will not print correct. You need to locate the data on the second halve

'For example when you want to display a line of text that is more then 8 chars long, (8x8=64) , byte 8 will not draw correctly

'Frankly i find the KS0108 displays a much better choice.
