Here I am trying to do A/D conversion and transfer the data to putty, to see the output but it seems it's not working. Need your help guys.........
My code:
| Code: |
#include <htc.h>
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
main()
{
int j,x,y,z;
OSCCON=0x70;
CMCON0=0X07; //turn off comparator
TRISA=0X01; //input port
ADCON1=0X50; //fosc/16
ADCON0=0x81; // right justufied
INTCON=0X00;
ANSEL=0x01;// select channel
TMR2=0X00; //clear tmr2
TRISB=0x00;
PORTB=0x00;
TRISC = 0x00;//
PORTC = 0x00; // CLEAR DATA LATCH
//TXSTA=0x24;
T2CON = 0x04; // POSTSCALER 1:1, PRESCALER 1:1, TIMER2 ON
//serial communication
RCSTA=0X80;
SPBRG=0x0C; //baudrate 9600
PIE1=0X00;
// TXSTA=0X20;
while(1)
{
for (j=1; j<3;j++)
{
ANSEL=j;
if(j==1)
{
ADCON0=0x81;
}
else{
ADCON0=0x85;
}
ADCON0=ADCON0|0X02;
if ((ADCON0&0x02)!=0X02)
{
TXREG=ADRESL;
TXSTA=0x20;
if((TXSTA&0X22)!=0X22);
TXREG=ADRESH;
TXSTA=0X20;
if((TXSTA&0X22)!=0X22); //hold till tx completess
}
}

or...
you could just use the example in the ccs C compiler examples folder as a basis of using CCS C, then you will get help here ! |

I have believed for a LONG time - after trying it - initially -
that it is so simplistically assembler derived -
that LOW tech C was a much more apt name.
I started work with PICs in assembler - and LOWtech C
was just not enough of an improvement for me to bother with.
and the lowtech forum?? whew - blind leading blind ... ;-))
just my 2 cents |
