More analoge input pins
Answer

Hi,

there are currently two analog inputs available on the XDK expansion board. For my application I acutally would need three but adding an external ADC for just one signal needs too much effort. I don't know how many of the eight digital inputs of the uC are still unrouted/available but I would suggest to make these available in a later version of the XDK/XDK expansion board. I guess that my application won't stay the only one where someone would like to read from more than (for example) two potentiometers without taking too much effort in selecting, ordering, interfacing and programming an additional external ADC.
What do you think about that?

Kind regards,

Hey everyone,

          My application also needs more than 2 adc pins. I know there is a way to reroute some of the expansion pins to go to the ADC but I have no idea how that is done. 

Could someone explain to us if this is possible and how to do it?

Actually only the pins PD0-PD7 of the controller are selectable for the ADC. But only PD5 and PD6 are available on the expansion board. If there is a possibility to also use other pins for the ADC I would be very interested in that.

Is it possible to share a simplified schematic of the XDK with us? I don't need one with every resistor, diode and capacitor but a schematic that shows which pin is routed where would answer also many more questions that may come up in future.

Hi Kai,

unfortunately we can't provide you schematics of the XDK since they are under copyright of BCDS and not publicly available.
Further, the XDK is built for testing and prototyping. Since your hardware requirements have by now become very specific, I'm afraid you either have to use the expansion board extensively or start creating your own hardware setup.

Kind regards,
Manuel
