TransferFunction Block

Hi,
I have troubles to use the Transfert function block with a TMS320F28035.
I try to filter a signal with a low-pass filter.
It runs good in simulation mode, but when I compile the block and then run the vissim diagram of my compilated block I have nothing in the filtered output.
Could you help me?
I join the diagram I use

You need 32 bit precision in the filter

Because your cutoff frequency is 5 orders of magnitude lower than the sampling frequency there are some small values in the coefficients. This requires use of 32-bit precision in the fixed point filter (you were using 16-bit). Here is an example of a run showing good agreement between simulation on the PC and results from the embedded target. Please find the modified diagram attached below. filter output comparison
