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 .
