I am trying to make my pic to send the value of the potentiometer (on PICKIT 1) through serial. At this step I am using an oscilloscope to see if it is doing well.

I wrote the code below, but nothing is changed on the scope screen when I move pot meter. Can you have a look please?

void delay_ms(uns16 millisec)
{
        char next=0;
        OPTION=2;
        TMR0=1;
        do {next+=125; while(TMR0!=next);}
        while(--millisec!=0);
}     

void main()
 {
     char byte;
     int state = 1;
     uns16 y=255;
     TRISA=0b11000010; //RA1 is input
     ANSEL=0b00000001; //analogue input ANO
     CMCON0=7; //to switch off the comparator
     TRISC.4=1; //USART will automatically configure input-output.
     ADCON1=0b00010000; //Fosc/32
     ADCON0=0b00000001; //reference voltage VDD
     SPBRG=32; // the nearest int to achieve 9600 baud for 20MHZ
     BRG16 =0; //8 bit generator.
     BRGH=0; //recommended to be set to reduce baud rate error. clear is better.
     SYNC=0;// select asychronous
     SPEN=1;//serial port enable
     ADCON0=0;   //ANO selected
     ADFM=0;     //Left justified
     ADCON0.0=1; //Enable conversion
     TXEN=1; //Enable transmission
     //delay_ms(y); //wait while he's converting
     
    ADCON0.1=1;  //GO but turned on.

    while (1)
    {
    byte=ADRESH;
    TXREG=00000000;
    delay_ms(100); //a short delay
    }
}
