It would be very nice to have support for Analog Input in eToys.
For a month or so, Etoys has a support for Analog Input, in a sense
that it can basically do what amixer
Hello all,
Thank you for your emails.

Arjun,
I composed an email that got longer with ideas, and sj must be rubbing off
on me because i stopped just short of clicking Send, and actually made a
wiki page. What I have no idea of how to do is actually to link back from a
wiki page to an email discussion for context.
Regardless, you
The SD is not really intended as removable media. The USB slots are. SD
is intended primarily as a way to augment the internal flash over the
life of the system. It is in an inconvenient location (there weren't
many other options).
We were/are most concerned about keeping water out...

There are lots of holes on the panel.

Mitch,
Thank you. As I wrote on http://dev.laptop.org/ticket/2800, what we
would like to have is C functions. Then, I can wrap them as Squeak
primitives. Probably I can just rip these functions from amixer, but
if you can tell me which, that would be good!
This is the
It might be nice if there were a driver to access the GPIO, but I didn't
see one in a quick scan of the kernel source.
It turns out that there is a GPIO driver - the source is in
char/drivers/cs5535_gpio.c - and it is available as a kernel module:
modprobe cs5535_gpio
However, nobody

And in any case, accessing this behind alsamixer's back is not a good
idea, because then alsamixer will be confused about the state.
Hmm, ok. We sure don't
Mitch,
There are ALSA controls defined for the analog input features. So we
already have driver support.

Hello,
OLCP just had a summer intern, Arjun Sarwal, who developed some low-cost
gadgets to plug into the mic port - temperature sensor, intrusion
detector, etc. He plans to document them and set up a framework for
documenting other similar hacks.
Ohh, that is cool. We would be happy
