Problem with Filter Design Tool

[riclerici]

Hello all: I'm trying to design basic filters with Filter Design Tool, and have the following difficulties:

Low pass IIR, 2d order Butterworth, 40db: changing the cutoff freq do not change the coefficients.
The filter Frequency graph shows the same as with the previous values, and the filter cuts at the same freq in hardware.

High pass IIR, 2d order Butterworth, 40db: created coefficients B exceeds the buffer size in 1 byte. Compiler issues "too many initializers". The freq graph is OK.
I've tried to change the line to COEFF_B[FILTER_ORDER+2], compiler finished OK but the filter dosn´t work in hardware.

Please, I need some guide to continue.

Hi,

I have reported this issue to our developers and they will solve it as soon as possible.
Unfortunately, due to the numerous on-going projects, I cannot precisely say at this moment when the fixed version will be released.

I apologize for the inconvenience.
