i have been reading the datasheet for ov7670 camera module. which pin is the red signal? which pin is the green signal? which pin is the blue signal? i have read the datasheet, and it is not clear which pin is the red signal, which pin is the green signal, and which pin is the blue signal.
The information you need is in figure 11 of the data sheet. There is no Red, Green, Blue output as such, each is digitized then the digitized value is read out across two bytes as shown in the diagram. Your software/hardware has to produce the control signals to the OV7670 then at the correct time, read the bytes from the pins to reconstruct the RGB values.
