Configuring Defines For 8-bit LCD

[lerameur]

so far so good, I do get someting on the lcd. I had wire connection problems
I found a chip that I have that did A/D conversion. Now I have another problem, my output value is always the same (around 500). It should read the input portC.0 from analog and display its decimal value to the lcd. The analog input is between 2 to 5 volt. I am using a Pic16F876a.

DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 1
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 0
DEFINE LCD_BITS 4
DEFINE LCD_LINES 2

Define ADC_BITS 10
Define ADC_CLOCK 3
Define ADC_SAMPLEUS 50

adval var word

TRISC = %11111111
ADCON1 = %10000010
Low PORTB.2
Pause 500

loop: ADCIN 4, adval
Lcdout $fe, 1 Lcdout "Value: ", DEC adval
Pause 100
Goto loop
End

end

Hi,
why don't you use the internal A/D of your microcontroller?
