    hello ,

    I have an AT89c5132 CPU embedded in AT89C51SND1 Development Borad.
    My problem is :I dont know how to record a wav file to the MMC.

    Did Atmel "burned" a internal software in AT89c5132
    (like they do in USB bootloader) ? or I have to write it?

    If I have to write it ,could I find some examples for 8051 or to the same chip I have ?
    since I dont know how to read ,write or even approach to this unique external memory.

    I searched in these forums about this but what I found was that people wrote codes for that but I couldnt find one example or at least a clear explanation..since i am a beginer in MMC.

    thanks for any help highlander11,

    you'll have to program it. Check the AT85C51SND3 to see what the differences are and what add ons you'll need to consider.
