My Project with an Olimex development board

 (This page is to response to an open-source project is kicked off by Olimex at: http://www.olimex.com/dev/projects.html).

I wanted to make a Sound Level Data Logger for a Sound Level Indicator I made for the local gym I attend as local residents were complainig about the loudness of the music.  The indicator helps instructors to easily see the sound level of the music while they are teaching.

As an improvement, I wanted to add a data logger so a log of the sound level could be written to an SD card and then read and processed on a PC.

I  also wanted to learn to code in C.  While looking for a suitable platform, I came asross the Olimex site and they had a development board that seemed to be suitable plus the opportunity to get it for free. I was informed that they liked my project and that I could get a board if I had a blog so the progress of the project could be followed.

I am now awaiting for the board.

    well, your project seems similar to the idea I had of recording accelerations (instead of sound).
    There are things I do not understand :
    * Do you wish to record the value of sound power , using an A/D channel or do you wih to use a digitalisation of the sound by your bargraph?
    * Do you intend to update the time of your clock by a serial link, or using an input device such as it joysticks (needs another A/D channel, in this case), or using another method?

    Seems the project was abandoned.

    Well, it seems : but it is (was) a nice project (rather simple and useful, the need being very specific), with some software parts common to other projects (writing to a SD with a stm32 is document in GNU-Linux Magazine France , March or April 2012; using a DMA and an ADC converter (and a serial port) is part of an article about fast Fourier transforms in GNU-Linux Magazine France , May 2012 -Im sure of the month) and I was trying to see if help could be useful....
    (I will get a stm32-103 stk next week , and I already have a programmer : my project is not an original one, but a matter of reading docs, but with all the docs, it seems simple...)
