NEED HELP in mapping of coordinates through CMOS camera and ATMEGA32 microcontroller.

[Ameen Yousuf]

hi everyone,

I am working on a virtual keyboard project, i plan on using the C3038 cmos camera module along with an AVR ATMEGA 32 microcontroller.

Intially i planned on projecting a keyboard image but is not feasable for me so i decided on using a keyboard printed on a paper instead.

For the time being i am collecting data and information about my project and components to use and have started the implementation actually.

My question:
Using the camera how can i map the coordinates of they keys? I figured out a way to detect the position of the key using laser light, but i cant figure out how to map the x,y coodinates of the keys.

Any help would be highly appreciated. Thank you.

How would you inerface camera to ATmega32?

using i2c protocol, communication between the camera and controller would be done through this. Also pins from the data giving a digital output would be mapped directly to the controller
