DetailsI brutally hacked the Oscilloscope to pieces and tried to make an x-y scope.
Please feel free to edit and contribute because I honestly have very limited knowledge of PCM data and the inner workings of rockbox =] |
This task depends upon
FS#10065to obtain actual samples on SWCODEC targets. I don't know if there is a way to get samples from the MAS on HWCODEC targets, so the scope is still based on peaks there. I've tested it on 5G sim, 5G 30GB iPod and Archos V2 Recorder.On the 5G and 5G sim, I can clearly see some parts of http://kapsi.fi/~jpa/stuff/other/youscope-wave.flac (for what it should look like, see http://www.youtube.com/watch?v=s1eNjUgaB-g ). Some music is uninteresting; when both channels are very similar, the display is just a diagonal line.
I feel this could still use more work. For example: more dots could be plotted, in a more optimized way, and the LCD doesn't have to be updated for every dot.
