I just finished a simple Spectrum Analyzer using Petteri’s implementation of PAWN and all I can say is that Petteri has provided a great tool. I have started from scratch on many small platforms over the years and this has been the quickest and easiest experience I have ever had in doing this. My little app is called spec_an and can be found with Petteri’s examples at <LINK_TEXT text=“https://github.com/PetteriAimonen/QuadP … r/Programs”>https://github.com/PetteriAimonen/QuadPawn/tree/master/Programs</LINK_TEXT>. Based on what I did I think the very best way to get on top of this is to study a few of the posted programs and then browse through the include files.
