That's an interesting idea -- I never considered using a dedicated DSP board. Thanks. That’s an interesting idea — I never considered using a dedicated DSP board.

At NI Week '06 (I think it was), one of the developers of the NXT-G software had a wonderful little robot on display. He used a DSP board to evaluate ambient pitch, and transfered this information to the NXT via the Hitechn ic protoboard digital inputs. The result was "whistlebot" - you could sing, whistle, or play an instrument, and the robot would move in repose (middle A might mean "go forward", while C would be "turn left", etc.). a really lovely implementation with a minimal of hardware, that I'd love to see pushed further - like what you have done here!

Your suggestion depends on there being file I/O functionality on the NXT brick. I didn't see any documented API to that effect, though I admit, I mostly skimmed the docs! The bulk of the time seems to be spent initializing the Bluetooth connection... Hi Noel, I’m glad you like it, and thanks for the feedback!

However, changing and recompiling a program whenever you wish to run it with a new set of parameters is seldom a good way to do things. You could save doing these steps by having the NXC program read the note and timing information from a file. Then all you have to do for each tune is to assemble the note and timing information into a data file and send that to the NXT. This would probably also speed up the process. Brilliant!
