Hi all, please help me, the example program page on the PIC16F88 ad converter did not work,
shows me error ANSEL =% 00010000
Greetings!

Hi,
WHICH example program ?, what page ? which 16F88 ? ...
please show your program listing here ...
so we can answer you something useful else than " may be it will rain, may be sun will shine tomorrow " ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
************************************************** ***********************
IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

It may be as easy as removing the [SPACE] between the percent symbol and the binary value as : %00000000. I don't know that, because (as Alain suggests) I have seen neither the code nor the error, but I am foolish enough to risk a guess!
Here is MPLAB Answer for this ghost space ...
just a WARNING ... but compiling still occurs ...WARNING Line 38: Bad token "%".
C:\PROGRAM FILES\MICROCHIP\MPLAB IDE\PROJETS\TWINAIR_LIGHTS3.BAS WARNING Line 38: 01110000 Malformed binary numeric, value truncated.
Loaded C:\Program Files\Microchip\MPLAB IDE\Projets\Twinair_Lights3.COF.
BUILD SUCCEEDED: Sun Apr 13 16:06:36 2014
note the generated HEX shows $70 for right scripting and $F0 for the wrong script

Hi, this is the code sample page of melabs,
Error when compiling throws me online 23
what happens?
Greetings!
' Name : ADCX18.pbp
' Compiler : PICBASIC PRO Compiler 2.6
' Assembler : PM or MPASM
' Target PIC : PIC16F88 or similar
' Hardware : LAB-X18 Experimenter Board
' Oscillator : 4MHz external crystal
' Keywords : ADCIN, LCDOUT
' Description : PICBASIC PRO program to read potentiometer on LAB-X18
' and display on LCD.
'
' Define LCD pins
Define LCD_DREG PORTA
Define LCD_DBIT 0
Define LCD_RSREG PORTB
Define LCD_RSBIT 6
Define LCD_EREG PORTB
Define LCD_EBIT 3
' Allocate variables
x Var Byte
ANSEL = %00010000 ' Make the pot input analog and rest digital
CMCON = 7 ' Set PORTA to digital
Pause 100 ' Wait for LCD to start
mainloop:
Adcin 4, x ' Read the pot
Lcdout $fe, 1, "pot=", #x ' Send value to LCD
Pause 100 ' Do it about 10 times a second
Goto mainloop ' Do it forever
End
Just FYI "CMCON = 7 ' Set PORTA to digital" actually turns off the comparators and doesn't set the ports to digital.
It also looks as if you need to set the ADCON bits 3-5 also to use ports as analog inputs.
Shouldn't this "Lcdout $fe, 1, "pot=", #x ' Send value to LCD" read "Lcdout $fe, 1, "pot=", DECx ' Send value to LCD"? I [U]think[U] the # returns ASCII and NOT decimail numbers. Which may or may not be what you are seeking.
Best wishes
thanks, proves what you suggest and I'll tell you then,
Greetings!
Hi all, this code works with adc pic, thanks for your help,
Greetings!
DATO VAR BYTE
CMCON=7
DEFINE ADC_BITS 8
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
ANSEL=%0100000
LED VAR PORTB.0
HIGH LED
PAUSE 100
LOW LED
PAUSE 200
INICIO:
ADCIN 5,DATO
LCDOUT $FE,$C4,DEC dato
PAUSE 300
GOSUB INICIO
END
You probably want GOTO, not GOSUB.
Robert
Thanks, that's the right way.
I'm working with a lm35z converter pic with 8 bits, as I can convert the value to degrees Celsius gives me?
