I try to use TouchScreen with Fez Raptor. I need to use Pin 7 of Socket 14 to read XR value. But in GHIElectronics.TinyCLR.Pins, pin 7 of Socket 14 is not defined. I Don’t know if it is intended or not ?
The socket type is X so you get only 3 GPIOs. That pin is part of the resistive touch interface, which is not directly supported in TinyCLR OS. But the pin is GPIO so you can access it directly.
Resistive touch is too old to be used today but there is some info here in case it is needed http://docs.ghielectronics.com/software/tinyclr/tutorials/graphics/touch.html
I forget that in Gadgeteer point of view X is only 3 pins.
Resistive is old, but it exists yet in my T43 Display !
I hope I can propose a new module soon for it.
Big part seems to be calibration, but with FEZ AI…
I was looking making a NuGet for resistive touch but i have soooo many other things I want to make.
