I need to design a 20 pin capacitive touch board and I am planning to add a driven shield. But it seems that there is no detailed design guidelines about the topic. I could use some help at least about key subjects like design constraints. 

I use STM32F051 Cortex-M0 microcontroller by the way.

Thanks, Hamdi.
