Serial Camera Control Bus (SCCB) interface/SPI

[BrendanP]

(I have posted the title to this incorrectly, I meant to write that SCCB is similar/same to I2C)

I want to do some work with 3G video transmission. I've done a bit with sms/DTMF control/txing/rxing on the PSTN or I wouldn't otherwise go near this. The hw issues alone are scary let alone the sw. Had a go at soldering 100 pin .5mm pitch connectors in a fry pan yet?

I've sourced a 3G module that is designed to work with a CMOS camera.



I just found this data sheet on SCCB.

This link was helpfull,

http://www.kanecomputing.co.uk/pdfs/d_module to cmos image sensor.pdf

It says on page 6:

"...A CMOS sensor is typically controlled via a SCCB (I²C) bus, a serial two-wire
interface. Depending on the sensor the host processor can control exposure,
gain, brightness, contrast, gamma correction, windowing, frame rate and output
data format..."

Phew! Quite project.

Have a look at page 11 (pdf 12) of that Kane document......
Section 4.2.
and page 12
and page 13

Thanks Dippy, I came across that part myself just now before checking back into the forum. I posted late last night my time.



You'll be hearing from me no doubt Dippy re. I2C advice down the track once the cameras arrive.
