Attachment is missing.
Can you post your complete project, so that we all can have a look at all of your settings? To do so, use Creator->File->Create Workspace Bundle (minimal) and attach the resulting file (do NOT use chrome, that still may not work).
HI again all of you.!!! Thank you very much.
dannaknight ; thank so much for your answer and sugestion, I have tried that before and Psoc C. give me build error for that.
Just wait my explanation about what I have tried before.
Bob : I have created a minimal bundle as you have suggested me.
First of all what I am intend to do :
I have 64 FSR( force sensitive sensor) arranged in an array of 8x 8.
Because the scannig method I would need to sequentialy connect to Gnd least columns in a given instant of time. That is the reason of the row of Demultiplexers.
But the issue here is that Psoc Creator give me an error with pin components where I am connecting Vdda and Vssa.
I have tried the solution proposed by dannaknight befor the actual one but with other component , the analog multiplexer.
In that case Psoc creator ask me for put pin component and does not place of Vref component. Is like que
On the other hand I haven't write code yet.!!!
I stoped the intention to do to solve the issue with hardware.
So thank you all of you for some help

Wouldn't switching be easier with a digital port? Since you are interested only in switching between Vcc and Gnd that could make your design much more simpler.
Using digital port would increase FR measuerment inaccuracy and add additional undesired noise
Hi Thank you very much for the suggestion!
I am wondering how can I use a digital port to conmute between VCC and Gnd would you Bob explain me with a simple diagram ?
I suppose you are talking about a digital input port.
In that case who will change the digital value from vcc to gnd ?
Any way this issue in my project may be worked out with a couple of MAX4674, 2:1 multiplexer. but it was no my intetion .
But I am wondering why Psoc 3 cannot do that. I would learn about that.
It is about routing optimization ?
Thank you guys
