Light/colour sensor for Papilio one 500k

3 posts in this topic

Hi

New to FPGA's and would like to know if there's a way to connect a light sensor to a Papilio one, i have seen some tutorials for the Arduino, but have found no information to do the same with the Papilio.

I really want to know how to measure an objects colour with a sensor connected to a papilio one or other FPGA and have the reading in RGB

Hello Kevinmoonbat,

It looks like there is an I2C based Color Sensor that should work just fine with the ZPUino.

Please take a look at the Nintendo WiiChuck Example in DesignLab for an example of using an I2C device on your Papilio board.

Keep us posted about your progress and please feel free to ask any questions.

Jack.

Any sensor that puts out a digital signal can be used, the challenge is writing the HDL to talk to it, and that depends heavily on the specific sensor being used.
