Code to Add Your Call Sign (or whatever) At Start Up.

The following routine causes the wanted text (in this case VK5XYZ) to be displayed on the uppermost line of the LCD.


b1=1				'go to the first position on the upper line of the display
gosub wrins			'go to the "write instruction" subroutine
b0=0				'make sure that the variable b0 is set to zero
loop 20:			'the number (20) used for the display loop must not be used elsewhere
lookup b0,("VK5XYZ"), b1	'use the counter b0 to successively place each character into b1
b0=b0+1				'increment the counter by 1
gosub wrchr			'go to the "write character" subroutine
if b0<6 then loop20		'the number in this line must equal the number of characters being displayed
pause 4000			'delay 1 second at the 16MHz clock rate 

To add extra data, commencing at the start of the second display line, use the above routine but start it with b1=192. Note that you can have a maximum of 16 characters on each line (including spaces etc)

This routine can be inserted before or after the battery voltage measurement at boot up, but must occur  before entry occurs to the circular measurement routines for frequency and impedance. Use the "Programming Editor" you download from Revolution Education to modify the file and load it into the processor. The "Programming Editor" is actually called BAS805.EXE and is around 30 megabyte long so you will have to have access to a DSL connection.
