Hello,
I have an Arduino pro 5v 16mhz, an mcp3002 (https://www.sparkfun.com/products/8636) and a camera (http://www.hobbyking.com/hobbyking/stor … 20TVL.html). How can I use the DAC chip to convert the analog signal from the camera to a digital signal that I can send trough my arduino to my pc? And is it possible to send it directly to my radio module instead of sending it trough the arduino?
How to use this chip? I have not tested SPI before, so all help is good for me 
Sorry to tell you but it’s not going to work. The ADC you have samples at 75,000 times/second. A video signal has a bandwidth of a few Mhz. You need a much much faster ADC. And even with that an Arduino is just not fast enough to handle the datastream. You might want to read this …
We did get it to work with the ADC that is intergrated in the arduino. But that was shitty quallity. The camera has bad quality from before…
Is it possible if we can get it transfered digitally directly to my radio module? Or is it the ic chip that is my problem? We have not got any signals out of the ic chip yet…
I find it hard to believe you got it to work with the Arduino ADC. What resolution are you trying to achieve ? What bit depth ? What frame rate ? Where did you store the data ? How did you know when to sample so as to get the video data and not the blanking interval ?
The quality with arduino adc was 50p, 1 frame every 10 sec. So it worked, but crappy. How to get it to work with the MCP3002?
If you say it does not work with the MCP3002, have you tested it your self? And have you other ADC to recomend? with more samples per sec?
