Who can tell me how the A/D converter works

Iám a starter so plaese keep it simple

[mister_e]

do a search for ADCIN to start.

WOW, Have you find that by your own

I like all this HELPFULL answers for BEGINNERS

Thank you very much

JARI,

Maybe if you were more specific with your question.

Do you just want to read the analog voltage on a pin?

Are you looking for an explanation about how successive approximation works?

Or, are you trying to figure out why the program you've already written doesn't work?

I want to know how I can read a analog voltage on a pin, and how to put this in
a program so I can set a other pin high or low.

Iám using pbp v2.44

You can read that in the manual which came to your version of PBP.
Here then a smal example with no comment. Try to find the comment in the manual.



@ DEVICE PIC16F877A,XT_OSC
@ DEVICE PIC16F877A,BOD_OFF
@ DEVICE PIC16F877A,LVP_OFF
@ DEVICE PIC16F877A,CPD_OFF
@ DEVICE PIC16F877A,PROTECT_OFF




DEFINE ADC_BITS 8
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
DEFINE OSC 4

ADCON1 = %00000010

TRISA = %11111111
TRISB = %00000000
TRISC = %10000001

LEDPIN VAR PORTB.0

VALUE0 VAR BYTE

CLEAR


START: ADCIN 0,VALUE0

IF VALUE0 > 127 THEN
LEDPIN = 1
ELSE
LEDPIN = 0
ENDIF

GOTO START
END

How about page 43 of the PBP manual?
Duh....
