Gaetino Posted October 19, 2013 Report Share Posted October 19, 2013 Hi,I just received my Papilio Pro board. I'm newbie to fpga world, and long time user of arduino platform.I wanted to convert my audio library made for arduino Due to the Papilio : http://groovuino.blogspot.fr/ Obviously, I use ZPuino, and until now it works great. I had to change the timer usage, I use the DELTASIGMA (great sound !) instead of Due DAC, had to change some constant definitions, but nothing too difficult (nice job for ZPuino developpers !) Now, of course, I would like to use more advanced features of the Papilio. Here are some questions : . RAM : when I declare a variable, or a table, is it automaticly stored in the RAM ? My goal is to make some audio effects like delays that need a lot of RAM. . FFT : If I understand the FPGA, it's a lot of gates that can be phisicaly programmed to make the functions I need. So I guess it's possible to "program" some FFT functions. I think that ZPuino doesn't use all the FPGA gates (at least on the Papiio Pro), so it must stay some "place" to add these functions. But can it cohabit with ZPuino ? in other words, can I load several systems on my board and make them exchange data ?will I have to learn VHDL ?The FFT would allow me to make some audio effects which need a lot of CPU, like filters, choruses... Thanks in advance, this board seems really great ! Gaétan Link to comment Share on other sites More sharing options...
