Hi to all,
I created my own OOT block. It has 6 inputs and 2 outputs and all are type
of float. I am using Signal Source block and sending constant signals with
different amplitudes at each input port.
When I run, the the GRC file and change the one of the inputs, outputs
changes after some time(~5 seconds). To examine the problem, I am printing
the following variables on the screen:
noutput_items, input1[1], input1[noutput_items], output1[1],
output1[noutput_items]
...
8192, 44, 44, 1, 1 >>> Input1 is 44 and outputs are 1
8192, 44, 44, 1, 1 >>> Input 1 is still 44
8192, 44, 26, 1, 1 >>> I changed the input1 to 26. Note that input[1] is
still 44. input[noutput_items] is 26 but output[noutput_items] is also 1!
8192, 26, 26, 1, 1 >>> The content of input1 is all 26, but the output is
still 1!
8192, 26, 26, 1, 1 >>> The output is still 1!
8192, 26, 26, 2, 2 >>> Now the correct output is found!
....
First of all, why the dimension of input and output is 8192(sometimes
8191)?
samp_rate defined for Signal Source block is smaller than 8192. I am using
1, 100 or 1000. But as you can see noutput_items is 8192. How there can be
8192 inputs if the sample rate is for example 10?
My module content is like the following:
------------------------------------
int myfunction_impl::*general_work*(...)
{
const float *input1 = ..
..
for (int i=; i<noutput_items; i++)
{
*my_function*(input1[i],...,&output1[i],&output2[i])
}
consume_each(noutput_items);
return noutput_items;
}
--------------------------------------
In short, I want that one input comes per second(sampling rate 1) and one
output is out and displayed.
Regards,
Ali
