LCD BARgraphs

Let's say I read maximum 50 volts and maximum 5 ampers ; so one "empty box" = 5 volts and one "filled box" = 0.5 ampers.
It's this "pseudo" code correct ?!

for y=9 to 0 step -1
if volts >= (y*5) then
    if ampers >= (y * 1/2) then
char = 3
LCDOUT $FE, $80, char,char,char,char,char,char,char,char,char,char
Endif
Endif

I'm sure it's another way, much easiers, but I have -till now- no ideea ...

Untested, likely needs some debugging, but at least the methodology should be clear.

LCDPos	VAR BYTE
volts	VAR WORD	' 0 to 500 representing 0 to 50.0 Volts
Amps	VAR BYTE	' 0 to 50 representing 0 to 5.0 Amps
Char	VAR BYTE	

FOR LCDPos = 0 TO 9
	IF Volts / 50 >= LCDPos + 1 THEN	' Fill in Volt Block
		IF Amps / 5 >= LCDPos + 1 THEN		' Fill in Volt + Amp Block
			Char = 3
		ELSE					' Fill in Volt Block Only				
			Char = 2
		ENDIF
	ELSE					' Don't Fill in Volt Block
		IF Amps / 5 >= LCDPos + 1 THEN		' Fill in Amp Block only
			Char = 1
		ELSE					' Fill with Space				
			Char = 32
		ENDIF

	ENDIF
	LCDOUT 	$FE, $80 + LCDPos, Char	
NEXT LCDPos

Thank You, I will post the results !
