16f877, ccs, adc, serial communication

[creativity]

hi,

i want to read two analog input and after converting them to dijital, i will sent them to serial port one by one. i have writen the following code but something is wrong, do you have any idea?

#include <16F877.h>
#fuses XT,NOWDT,NOPROTECT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12

void main() {

long int input1;

setup_adc(ADC_CLOCK_INTERNAL);
setup_adc_ports(ALL_ANALOG);

//delay_ms(2000);

do {
set_adc_channel(0);
delay_cycles(60);
input1 = read_adc();
putc(input1);

set_adc_channel(1);
delay_cycles(60);
input1 = read_adc();
putc(input1);

} while(TRUE);

}

What do you mean by "something is wrong" ?

Tell us what you expect to see, and what you are actually seeing.

I expect to read the serial output of 16f877 with a matlab code given below. I gave a sinus signal to one input and zero to the second one. i expect to see a sinus with some zeros inside (one sin signal and one zero, and so on) but i only see some random signal. as you see more than "something" is wrong

s1 = serial('COM3', 'BaudRate', 9600,'Databits',10);

fopen(s1);

eye=zeros(512*2,1);

for i=0:1
eye(i*512+1:i*512+512) = fread(s1)
% plot(eye)
end

plot(eye);
fclose(s1);

How many Databits should there be?...

Best Wishes

i changed code to the code below and it works:

// 2 channel Analog Input //
// 1 channel serial digital RS232 output//

#include <16F877.h>
#device adc=8
#fuses XT,NOWDT,NOPROTECT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, parity=N, bits=8) // Jumpers: 8 to 11, 7 to 12

void main() {

long int input1;

setup_adc(ADC_CLOCK_INTERNAL);
setup_adc_ports(ALL_ANALOG);

//delay_ms(2000);

do {
set_adc_channel(0);
delay_cycles(60);
input1 = read_adc();
putc(input1);

set_adc_channel(1);
delay_cycles(60);
input1 = read_adc();
putc(input1);

} while(TRUE);

}

thank you for all replies.
