Hi Glen, thanks for your suggestions. Unfortunatelly I cannot avoid to use FreeRTOS because the project is based entirely on it. I'm developing on an DMR radio option board and I have to interface it with the radio, so a lot of code is already written.
Now I will made a try. Just to know, without to examinate the entire sorce base, you know which are the parts not related to the encoder? Thanks, Daniele.
