There are quite many informations (including PSOC Designer 5.0 ) about what is shield electrode and what signal comes out.
In PSOC 1 the Shield was an output from PRS ( so digital).
In PSOC 3 architecture I couldn't spot any message about shield electrode signal orgin.
From available pin assigment I guess it's analog (only digital pins are not available)
Does anyone know where to read about implementation changes?
The shield electrode signal is a digital output signal available on any GPIO pin in PSoC3/5. The new version of the CapSense component in PSoC Creator 1.0 Beta 5 will also allow it to be driven on to SIO pins (this is currently a tool limitation, not a chip limitation).
