problems with the current setup_adc_ports()

[Guest]

CCS complier is not using the setup_adc_ports () function correctly. In order for it to work i need to download version 3.249. Does anyone have an idea how to fix the code so that I can use the below code with my current version.

#include <12f683>
#device ICD=TRUE
#fuses intrc_io,nomclr,nowdt,noprotect
#use delay(clock=2000000)

#use rs232(debugger)

#define AD_CHANNEL_POT 0
#define GREEN PIN_A2
#define YELLOW PIN_A5
#define RED PIN_A4
#define LED_ON(x) output_low(x)
#define LED_OFF(x) output_high(x)



void main(void)
{

int32 _fixed(2) volt;
int8 adc;
setup_adc(ADC_CLOCK_INTERNAL);
setup_adc_ports(AN0_ANALOG);
set_adc_channel(0);



while(TRUE)
{

//use read_adc() to read the pot value, store to the variable 'adc'
adc = read_adc();

//Here we convert the adc value into a fixed point decimal representing
//the voltage in a range from 0.00 to 5.00
volt = (int16)adc; //0-255 becomes 0-25500
volt *= 5;
volt /= 2.55;

//Display the voltage on the debug monitor. We use printf() and the
//escape character for fixed point decimal (%w)
printf("Volt: %w (%x)\r\n", volt, adc);


LED_OFF(GREEN);
LED_OFF(YELLOW);
LED_OFF(RED);

//turn on green LED if voltage is over 1.25

if (volt <= 1.25)
LED_ON(RED);

//turn on yellow LED if voltage is over 2.5
if (volt <3> 1.25)
LED_ON(Yellow);

//turn on red LED if voltage is over 3.75
if (volt >= 3.75)
LED_ON(Green);

delay_ms(250);

}




}

What 'current version'.....
We are not telepathic.
What doesn't work about it?.

We had problems using setup_adc_ports() too.

Compiler 4042 to 4051.
Compiling for 16f886

Sample:

setup_adc_ports(sAN0|sAN1|sAN3);

.. makes (this is from 4050)::

04F2: BSF 03.5
04F3: BSF 03.6
04F4: MOVF 09,W
04F5: ANDLW C0
04F6: MOVWF 09
04F7: BCF 03.6
04F8: BCF 1F.4
04F9: BCF 1F.5
04FA: MOVLW 0B
04FB: MOVWF 00

but should (this is from 4038):

04F2: BSF 03.5
04F3: BSF 03.6
04F4: MOVF 09,W
04F5: ANDLW C0
04F6: MOVWF 09
04F7: BCF 03.6
04F8: BCF 1F.4
04F9: BCF 1F.5
04FA: MOVLW 00
04FB: IORLW 0B
04FC: BSF 03.6
04FD: MOVWF 08

So ADSEL are not written.

He is on a 12F683, and the current version, correctly accesses port 9F, and sets the specified bits on it. Hence my question 'what compiler version'...
The alternative 'setup_port_a' function, also does the same, as does the manual version:
