DEU analog 16 input PWM 16 output

Good day,

Is possible to expand the ADC from 12 inputs to 16 inputs.

I use only one i2c port ( this if a port is required for expansion ).

Also would like to expand the PWM outputs to 16.

If possible, like a tip how to approach this.

Regard,

Leen

An analog multiplexer like the 74HC4067 can handle extra analog inputs, needing 4 digital outputs to address it: http://www.nxp.com/documents/data_sheet/74HC_HCT4067.pdf

For PWM expansion this might be handy: http://www.adafruit.com/product/815
