I know that if I have not assign any pin in my psoc creator project, creator will automatically assign them to suitable pins available.

   

 I created a project in which Vddio2 = 3.3V and all other voltage = 5V. I want to know that is there any way to ensure that  "PSoC creator doesn't assign any pins to 3.3v bank of psoc" ? I will manualy assign pins to 3.3v bank.

Creator does not auto assign Vddio pins, they are fixed pinout. However you have

   

to tell Creator what what Vddio you are going to use for each Vddio domain, thats

   

done in the .cydwr tab of Creator.

@dana: Creator does automatic assignment - otherwise no project would compile without assigning all pins first. But the order seems to follow a heuristic (e.g. LCD component go to port 2 IIRC). There is no real way to limit this assignment. If yu have special restrictions, its best to assign all pins manually. There is a Creator extension (by keez if my memory serves me right) that could derive the right pin from how the pin component is named.

@hli, my earlier statement -

   


   

Creator does not auto assign Vddio pins, they are fixed pinout.

   


   

I stand by.

The question is:

   

I want to know that is there any way to ensure that  "PSoC creator doesn't assign any pins to 3.3v bank of psoc" ? I will manualy assign pins to 3.3v bank.

It is not the VDDIO ins.

I am not sure if there is a way to stop creator to assignment pins according to different VDDio value. I did it manually.

No, Creator does not allow that.

HL, I did misread that question. There is no auto placment to

   

a Vddio level in Creator, you would have to do that manually,

   

paying attention to route specific constraints for some functions.
