PSoC Creator & Designer Software

Trying to use assign pins 4_0, 4_1, 4_2 to pins and pin wizard will not show them as a selection

offering, yet they are shown on package and in user manual and on schematic.

They are not called out in any other schematic component.

What am I missing here. Part on Pioneer board is CY8C4245AXI-483

Hi,

I tried to create a project for CY8C4245AXI-483 with PSoC Creator v4.4

schematic

Pin configuration

Note: If you are using CY8CKIT-042, P4_0 and P4_1 are pulled-up so you may want to use open drain.

In the Design Wide Resources > Pins

All P4[0], P4[1], P4[2] are shown as candidates

001-Pin1.JPG

So I assigned P4[0] to Pin_1, P4[1] to Pin_2, P4[2] to Pin_3

002-pins.JPG

And I could generate application.

So in your case I would think

(1) The device selected may be wrong (Not CY8C4245AXI-483)

(2) You have already used P4[0], P4[1], P4[2] for other use

If you can attach your project, others may be able to figure out the problem.

Attached is the project I created, main.c has not been modified, though.

Dana,

Only 40 and 41 pins are available on the CY8CKIT-042 Pioneer board. You may find all pins available on KIT-042 Annotation stub

Surprised that pins are brought out to a header on board, labeled but inaccessible.

The I2C pullups under some situations could be ignored or useful as well for other

uses. Or jumpered on the board.

Seems like those pins should not be excluded, that they can be used for other

designs. After all pins are precious on small package low cost parts.

Regards, Dana.

Is it possible to hack Creator to show these pins that could be dual purpose ?
