default value is 2, and the range is 0 to 6. This option is used by the
PRINT, PRINT2, PRINT3 commands, the DISPLAY command, and the
WRITESDI and PRINTSDI commands.
Example: print 5.00000 (prints 5.00 (default set to 2))
digits(5)
print 5.00000
(prints 5.00000)
digits(0)
print 5.00000
(prints 5)
--- Built In Display / Keypad Commands —
DISPLAY Basically the same as print except the output is to the local display. The
curser will be left at the end of the printed string. Also no carriage returns
or line feeds will be sent at the end of the string as they would clear the
display. If the display is not turned on before this command is used then
the display will be turned on automatically.
DISPCLEAR Clear all text from the display and position the curser at the home
position. If the display is not turned on before this command is
used then the display will be turned on automatically. Using this
command is an easy way to turn on the display.
DISPCURSER(##) Position the curser at position ## where ## is 00 to 19. This allows a
message to be displayed once and some portion of the screen updated as
needed without having to redisplay the whole screen.
Example: dispclear
display “Battery Volts = “
for x = 1 to 1000
dispcurser(16)
display batt
next
dispoff
end
DISPOFF: Turn off the display now. If this command is not used the display will turn
off automatically when the system has no more tasks to perform.
INKEY: Wait for a key to be pressed on the built in key pad. If no key is pressed within 30
seconds, a 0.00 is returned and program execution continues. The following table
lists the values that will be returned for the different key presses.
