analog2pi

I uploaded a screen cap of a scope display program I wrote last year. It's located at the end of the Project Details section. It's running on a Model B+ with an older version of raspbian. It's actually displaying data captured with the analog2pi interface - before the DMI api was changed. And I spent far too much time on it making it look just like my trusty Philips scope.

Just a little tease to hold you over while I work on the module rewrite...

Sorry about the lack of progress. The new DMA API is quite different, but I think I have it almost figured out. I'm going to use the spi-bcm2835 code as an example, and I'll use device tree to reserve channels.

If you can't wait, you can use the code at my old site to get it working (with only one channel) now. You'll have to use an older version of Raspbian though.

Made it square.

Posted files for old version that was a character device. Second channel (i2s) won't work with this version of the interface.

It doesn't include code since I'm in the process of writing a proper sound device module. My previous code was a simple character device, but it worked just fine, and served to prove the concept.
