[QUOTE=Rob1n;790440]Removing the battery for a short while should get things working again (until the next time you run fcamera).

it's not working ... i removed the battery for 1-2 min ... restarted
LEDs not working!
they show missed calls, IMs etc ... but not charging!

Optical Format - 1/3.2 inch

Pixel Count - Approx. 5 M 2,584(H）× 1,960(V)

Cell Size - 1.75μm × 1.75μm

Output Signaling - RAW

Frame Rate - 12 fps at full resolution

Control Bus - I2C

Image Signal Processing - None
Youch the small cells explain why the images are so noisy. Thanks for getting me in the ballpark to get started. I'm using the n900s camera to simulate a fisheye camera mounted on a rig. I'm curious to see how good the optics really are on this.

One other question...is the focus mechanical or purely software? I can run the calibration at diff focus levels to test myself but its helpful to know ahead of time.
.
The lens actually moves for focus, so it's mechanical.

Fcam is simply a-w-s-o-m-e.

Ouch...it would be useful to have the ability to hard lock the focus by default...otherwise any calibration won't hold.

Fcam doesn't appear on on the catalogs. (Devel, extras-testing, extras).

What is the difference between fcamera and BlessN900?

Re: FCam - a new camera API for the N900
 
Will you promote the current version of fcam-drivers to Extras or will you do more iterations?
There are several packages depending on it.

Re: FCam - a new camera API for the N900
 
I just promoted fcam-drivers to extras. There's possibly a crash bug in it somewhere, but it might take us a while to track it down - it's very intermittent. We're going to rev fcamera at least once more before promoting to extras, since the front LED use isn't working right for everyone.
