PRS based wav player
i've been trying to reproduce wav sound using PRS based on these documents/articles:
i am currently using psoc4200 kit. i've finished the code and all, heavily based on 1st document. but in test, there's nothing on the prs output pin (i used analog scope to see the signals). at first, i suspect the prs not working. so i trim down it's clk, and yes, i can see some noise on the out pin. but after rc circuit, there's still nothing. so i am at lost here.
i knew there're many suggesting using the idac/vdac. so instead of prs, i used idac. yes, eventually, i can see some signals and i can also heard them in earphones, although they're in pretty weak volume.
so i just wonder, if someone really have trying the prs way, and succeed, maybe can give a little hint here.
