fix tris i/o bits

[fvnktion]

Im sure this is a newb question, but i have not been able to find an answer by searching the reference manual or forums.

Im am trying to fix an0 and an1 on 16f88 as inputs. I am trying to use the rest of porta pins (2-7) as outputs or inputs. I need to be able to use the set_port_x() without affecting an0 and an1. I need output pins on porta to change simultaneously, as they are switching inputs on a toggled motor control driver.

Is there a command that will fix these the an0,1 ports and not affect them when using the set_port_x() function??

Thank you for your help!

You could use the #use fixed_io() statement, and specify which
pins on Port A are to be used as outputs. All remaining pins on
Port A are then considered to be inputs by the compiler.

Thanks for the reply.

I am not sure if this will be conflicting using the ADC, as they will be used as analog inputs rather than digital inputs?? Does the fix_io function take this into account?

essentially what i am trying to do is this:
#include <16F88>
#device ADC=10
#use delay(clock=8000000)
#fuses INTRC_IO,NOWDT,NOMCLR,NOPROTECT,NOCPD,NOBROWNOUT,NOLVP//INTRC_IO //nolvp for lcd
//#use fixed_io(a_outputs=PIN_A0, PIN_A1)


void main() {
long int Tvalue,tilt;
//setup adc values
setup_oscillator(OSC_8MHZ);//sets internal osc multiplier
SETUP_ADC_PORTS(sAN0 | VSS_VDD);
SETUP_ADC(ADC_CLOCK_DIV_32);




while(1){
//read adc value
Tvalue = READ_ADC(ADC_START_AND_READ);

//adc tilt value eval

if (Tvalue>1015)
tilt = 0b00000100; //Tiltdown
else if (Tvalue>991)
tilt = 0b00011000;//tiltup
else if (Tvalue>950)
tilt = 0b00001100; //0b07;//tiltLeft
else if (Tvalue>915)
tilt = 0b00010000; //0b0001111;tiltRight
else
tilt = 0; //0;

OUTPUT_A(tilt);
}


reads portan0, evaluates state, outputs on porta, not using pina0,pina1.

Is there an easier or better approach to using port a as input/output simultaneously with Analog inputs and the ADC??

Thank you for the help!

You need to make the changes shown in bold below.
