hi thank you vinoth ...
Okay you said that it is possible , but I was thinking that since baud rate is 57600 means data is coming too fast so plot will be also fast that we cant analyze anything in it... ?
Let me tell you that my data @ hyperterminal is like this
211 121
212 32
43 76
231 104...
hello there friends...
I just want to ask that is this possible to plot real time data at baud rate 57600..
If it is possible the which software is best for this either C++,VB,MATLAB..
Please guide me I want to plot my data real time , have already tried with MATLAB but baudrate is high and...
wait something going wrong :???:
When I changed the frequency 75 hz it sampled very well but not sampling well at 30 or 40 or 50 hz ..
this is plot of sampled at 75 HZ:shock:
9600/10 bits = 960 bits/sec
there are 4 character data 3 for my two ADC channel (10 bits) and 1 for CLRF
so 960/4=240Values/Sec
if I give 5 hz then 240/5 =48 sample/sec
and if I am giving 50hz then 240/50 =4.8samples/sec
If I am not wrong about above calculation ....?
See the result when 5 hz is...
I have given delay of 1 us ...
Data is coming too fast on the terminal ...
But there is not enough sample Like this

I am using 9600 baud rate and 20Mhz crystal oscillator ..
ADC_Read read ADC outputs and UART1_Write writes the data means transmitting to serial port...
Yup I have changed loop timing in micros so it can loops as fast as possible...
Hello Friends...
here is my code for PIC16F877A using two 10bit ADC ..
unsigned int temp_res;
unsigned int temp_res1;
char buf2[6];
char buf[6];
int i;
void main() {
UART1_Init(9600);
delay_ms(100);
TRISA = 0xFF;
CMCON = 0x07;
TRISA = 0xFF; // PORTA is input...
hello friends,,,
I am just done in plotting real time data in simulink ... but there is only one problem i.e x-axis of the scope is not moving/ changing , I mean that all data is plotting on the same screen that if I have simulation stop time 1000 then X axis of scope squeezes the screen and...
yeah that's rite I had already tried this one too but the problem is that it is not working for my script i.e
fid=fopen('file.txt');
fseek(fid,81,'bof')
for i=1:40
A=fgetl(fid)
A = str2num(A)
end
fclose(fid);
I am getting A from here
A=fgetl(fid)
If i changed it to
A(i,:)=fgetl(fid)
So it...
hello friends ...
here is my simple code..
for i=1:100
pause(0.05)
y(:,:,i)=i+rand(1,3)
end
it generates "y" like this on command window
y(:,:,1) =
1.4091 1.4740 1.9090
y(:,:,2) =
2.5962 2.3290 2.4782
.
.
.
.
y(:,:,100) =
100.1526 100.8330 100.1919
and...
thanks ALOOOt...!!
Its working... :)
In my scope(simulink) my values along Y axis is changing ..
Any help that how to chagne X axis of scope with the loop.. so that it looks real time :)
Again thank u ...
hello There...
I want real time data view on Simulink ..
here is my code
fid=fopen('file.txt');
fseek(fid,94,'bof')
n=0;
for (n=0:6)
pause(0.5);
A = fgetl(fid)
A=str2num(A)
end
fclose(fid);
this takes line from a text file , I am just stuck that how do I update Base workspace as...
