How can I see sine wave on logic analyzer?

it gives errors but i did not understand what this code about sorry im new in this thing

hi what errors do you get

is anyone here good to fix them.

It would really help if you guys would read the posting instructions so your source isn't a jumbled mess of lines.

Don't post off topic noise to an existing thread, start a new one.

The sine table looks awful. How exactly did you create this, and how does blasting values to the DAC use the timer to pace the output?

your answer is not the answer to my nquestion. so if you want to insult people please do this somewhere else. as answer to your question this is a homework and i choose 2600Hz frequency. i need to generate a sine wave that has 2600 Hz frequency using timer interrupt. not anything else. Im new in this thing and i might wrote the code wrong. if this, please correct me KINDLY.

this is the code that gives the sine table value. i did run it in matlab and got the values.

clear;
close all;
N=1000;

frekans=2600;
fo=10000;

for i=1:1:N
        x(i)=2047*cos(2*pi*frekans*i/fo);
end
figure; plot(x);

B=input('\nCikis dosyasinin ismi   *.txt = ','s');
fid=fopen(B,'w');
for i=1:1:N
    if (x(i) < 0) x(i)=x(i)+4096; end

    xx= round(x(i));

    if (xx>=4096) xx=xx-4096; end

    %fprintf(fid,'%i \n',xx);
    fprintf(fid,'%4x \n',xx);
end
fclose(fid);

and this is the code i wrote

#include <stdio.h>
#include <ADuC841.h>

sbit LED = 0x0B4;

void timer0(void) interrupt 1 //interrupt no. 1 for Timer 0
