what about recording in the sansa E2xx series?
« on: June 04, 2007, 03:30:32 PM »
is in the agenda the recording capability in both things (FM radio and mic),I'm just asking I was thinking that it might be a great thing to have the possibility to record audio in rockbox.

Hardware is not documented at all, so if somebody reverse-engineers that part you can have recording

We actually do have documentation for the AS chip.  I believe Austriancoder and others have already had some luck with line in (the radio patch uses it IIRC).

By the way, is the documentation that the Rockbox developers received from Austria Microsystems (and all the other documentation) available to the public?

Since Rockbox is an Open Source project I thought that the developers might share the documentation or data sheets they use to reverse-engineer drivers and stuff.

No.

Anything thats reverse engineered is typically shared, however the datasheet's license agreement prevents them from being shared directly.

No. The code is open source. In the case of AS we managed to get the datasheets by accepting an agreement that we do not redistribute them, but we are allowed to publish the resulting code.
(I had completely forgotten about that AS deal)

The E200 series has a line in? Through the proprietary port on the bottom I presume...
Please confirm.

Now that Recording (in Rockbox) supposedly works I'm getting very interested in this unit.  :P
