[Elphel-support] Extension of stereobase and elongation sensor's cable length

[Oleg]

Hi,

To do so we have connected two cables in serial, so we obtained total cable
> length 450mm + 450 mm = 900 mm between 359 board and each sensor board.


There's no guarantee this length will work.

We try use control page http://192.168.0.9/359/10359_controls.html but it
> is not clear which values I have to change.

I'd need to test if it still works fine.

A better way to adjust phases is this one:
Go to: http://192.168.0.9/  > Parameter Editor > Check "Unsafe" >
"View/Edit Current"
Or here's a link
<http://192.168.0.9/parsedit.php?title=Parameters+for+groups:+unsafe+&CLK_FPGA&CLK_SENSOR&SENSOR_PHASE&I2C_QPERIOD&I2C_BYTES&MULTI_PHASE_SDRAM&MULTI_PHASE1&MULTI_PHASE2&MULTI_PHASE3>
.

The phases are changed with:
SENSOR_PHASE - "system board - MUX" (in stereo setup)
MULTI_PHASE1 - "MUX - sensor 1"
MULTI_PHASE2 - "MUX - sensor 2"
MULTI_PHASE3...

bits[18:17] - 90 degree shift
bits[15:0]  - fine steps (with sign) 0xff01...0x00ff
