Help On Camera Card

[chyang]

I have bought an EagleTec camera card which support 1.3M pixels resolution, I checked before buying, it doesn't have linux driver support. But I would like to have a try for that. Now it comes, I need to figure out how to begin, is there any clues on sharp's CE-AG06, any driver sources and application sources?
Thanks.

Sharp's camera driver is closed source, their camera application too. Opie-Camera is open source, but it won't get you much looking at it, because it talks to the closed source driver via their serial protocol.

If you want to do a proper driver, look at v4l[2] and implement a driver for that subsystem. Then we can talk about adding v4l support to Opie-Camera.

I'd be interested in v4l support in opie-camera as I have a ratoc card and am thinking of trying to get a web-cam working. Out of interest does opie-camera also handle video from the Sharp camera, if not this is something else I'll look into?

First step (for me) is to find a suitable web-cam and cross-compile the drivers.

Yes, Opie-Camera can do video, but for the Sharp Camera this is nothing different from snapshots since it only supports grabbing full frames anyway.

Qtopia 2.1.1 has a v4l application - I'd like to see that getting merged into Opie-Camera.

  CompactCam driver ver 0.2

--------------------------------------------------------------------------------

This is PRETEC's CF type compact cam driver.

We tested this driver on Linux 2.4.19 iPAQ and 2.4.24 x86 with vic.
Only VGA model works in BW mode. 1.3M SVGA model doesn't work.
This driver is written for a part of MIRAI project.
see URL below for more information about MIRAI.

Softwares:
  compactcam_cs.o ... driver
  rw              ... direct register view/set util.
  siorw           ... direct sensor register view/set util.


Installation:

  - set TOPDIR/CC/APCFLAGS appropriately in Makefile.
  - make
  - cp compactcam_cs.o in /lib/modules/<ver>/pcmcia
  - put these lines below in /etc/pcmcia/config and restart pcmcia.

  bind "compactcam_cs"

card "CAMERA CARD CC130CF"
  manfid 0x504f, 0xcf13
  bind "compactcam_cs"

BUGS:
  might freeze with xawtv.


Note:
  If you try to hack the driver, you probably need the exact chip-level
  hardware specs. We(Omoikane Inc.) got part of needed documents from
  PRETEC and wrote the driver along with a lot of assumption and reverse
  engineering of WindowsCE driver.
  Despite of our struggling, we cannot got the correct way to get
  orignal clocked digital image data from a sensor.
  If someone could get this, the driver would be easily improved
  so that it outputs color data with low IO bandwidth.
  For current version, the missing point is which pixel is which color
  among the Bayer pattern.


Wish:
  We wish PDA Linux users to tell mobile device vendors that you
  want to use with opensource. We believe most vendors cannot
  understand how much people in the world want to use thier devices
  with opensource. Consequently this information will help
  developers/researchers to get hardware information from vendors.

hi, Mickey:
  I have made the driver part work under my SL5500, would you like to give some suggestion in selecting the client for the V4L driver?
  Thanks.

Sorry, but to be honest, I have no idea at all about the v4l API - other than to know what is is for.
