CCD BW Cameras

I think a BW camera can be much faster

than other detection systems , if the

software is done right .

But its tricky getting a clear image

while its rotating . So if i rotate

in the opposite direction , they cancel

and the camera sees a steady image .

A stepper driven mirror , will at times

be moving exactly in the opposite

direction of the camera rotation ,

and maybe i'll get a high resolution

image for the ARM7 team to process .

Analog preprocessing can speed

up the decision making , and lessen

the load on the ARM mcu's .

Since its analog , i can diffenciate

and send it to comparators .

but the Vref will be only a small CAP,

charged by a PWM from the MCU !

This allows mcu to set the level on

the Vref , dynamically .

Say i want to find edges on a scan

line . The diff comp will switch low

when the edge comes .

This is all at 10's of microseconds

range ..

The camera can accurize any phase

lags in the path to the Vref .

Result is , if its nite , and you move

5 degrees to the right , it will know ,

And this is with camera movement .

Im doin lots of ARM stuff .

Ill be handing out a better "loader"

to flash into the top 8KB of ARM 7 mcu .

It will be a no excuse loader .

You will be able to boot , with just

dip switches and keypads .

No need to set up the higher level

stuff like USB , RS232 , EtherNet , SPI

In the 8KB , will be a code generator

that will create code in SRAM dictionary ,

so , if needed , it can actually rewrite

itself .
