The output of the CCD is an analog voltage for each pixel representing the amount of light falling onto the pixel during the integration time. I buffered the analog signal using a unity gain follower and connected it to the AVRs ADC. Now you have to time the conversation with your pixel clk and your done. A black line on a white background would give you a range of pixels with lower voltage in your result. You need to create Clk & Si signals as shown in the diagrams above.

I'm trying to detect a black line in a white underground, but I don't know how to interpret the signals from the camera in order to follow the line. I'm using a freescale microcontroller.

For the analog Output of the CCD i used a OPV amplifier with a gain of about 2 (i don't really remember). Sorry I do not have a drawn diagram. Tobi Hi,

Include compat/deprected.h and try to compile again. alternative you could define the cbi, sbi macros yourself: #define sbi(port, bit) (port) |= (1 < < (bit)) #define cbi(port, bit) (port) &= ~(1 << (bit))</compat> The problem is that the source was for an older version of avrgcc.

where did you get these line sensors?

Thank you,
