			Oleg, do you have an idea of why it's darker ? Did you tried to analyze what is exactly the difference between images ?

			It is better to use all i2c functions from an include, not rewrite them in your PHP code. http://elphel.cvs.sourceforge.net/elphel/elphel353-7.1/packages/web/353/php_top/i2c.inc?view=markup

			3 MPix sensors work, but sensors_init.php show ffff ffff f...

			In sensors_init.php:
			send_i2c($width,$bus,0x4800+$i,$init_pars[$i],$raw=0);

			0x4800 work with 5MPix sensors only. It would be better to make it variable.
			0x5d00 is for 3 MPix sensors. You can detect the current sensor by elphel_get_P_value(ELPHEL_SENSOR).

	~~1800~~.02.13.~~2008~~: ~~Wrong device type was selected~~ in ~~the project x359~~. ~~This caused the programming file generation error~~: ~~that was about differential pin SDNCLK (~~the ~~pinout is not~~ the ~~same~~ for different ~~packages~~).		I tested the last 359 binary firmware.

			My test was made with one 353 board, one 359 and 2 sensors 1 color and 1 monochrome. The color sensor have a 3 times longer cable.

			Longer cable neeed phase adjustment. I tested the cable directly with a 353, it also needed a phase adjustment. With + 32 it was working fine.

			Questions :

			* what is sphase in /359/switch_to_ch2.php?dr=0&sphase=0x00000007&channel=1&cc=1 ?
			* does /359/switch_phase_dcm1.php?phase_shift=2 work ? i tried to swift it 50 times to both directions, no changes.

			Remarks:

			* It should be possible to set hact & data phase shift independently.
			* The sensor should be reseted after changing the phase. It may sometimes work without, but sometimes it can crash the sensor.
			* We should be able to change phase for all 3 channels independently. (they can have different length)
			* We need to rename PHP files to make it more logical.
			* I need to understand the exact and minimum commands to call (to transparently send channel 1) in order to add it to the default 353 firmware setup. In this setup the camera should work with camvc without doing anything else.
