    Wink Developing spectrum analyzer for 20x4 lcd

    I'm developing a dos-based mp3car player using xaudio sdk.
    I have coded a spectrum analyzer that runs smoothly on my hitachi 20x4 lcd.
    Anyone interested? Any suggestions for a dos player?

    Hi Fosgate,
    yes I think I will give the source code ( I'm writing the analyzer in C for the Djgpp compiler ) but for the moment my mp3player is not ready for distribution, it is still in progress...I have to finish the playlist manager and the control interface, I'm working hard :-)

    Hi,
    if anyone wants to help me for the moment and wants to try my user-programmed character set on his lcd, please e-mail me at: [email protected]
    I will reply sending a little test program (95K exe file) that writes on the lcd some vertical bars. I'd like to see if it works ok on all 20x4 parallel or smaller (hitachi-controlled) lcd displays.
    I have only to fix a little problem with the reported frequency magnitude (something wrong with the FFT) and then the analyzer will come!

    Finally, someone who wants to make a new program !!! Will it work with HD44780 LCDs , the ones that are wired for winamp? Will it be a winamp plugin , and could you make a winamp plugin version

    Yes my program is designed for the HD44780 controlled LCDs, anyway I never went into winamp plugin programming, but if anyone out there knows how to code a plugin it would be really nice!
