hi i really new to psoc i'm working in a project and i got and error in the design the error is this: Pin guidance unavailable: Resource limit: Maximum number of Datapath Cells exceeded (max=4, needed=8). First i use a counter for select the mux output but i thought the error was in that counter because something i read about the error so i make it with the flip-flops but i still having the error. sorry for the bad English i hope you can help me

Welcome in the forum, Yordi.

   

Easiest will be to 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.

tanks to answer i found the problem or i think so, i had read a lot of papers  i found that each of  8 bit pwm are implement in a UDB cell,a 16 bit pwm use 2 of this.the psoc4 only have 4 UDB,s so i only can implement 2,16bit pwm blocks. that's right ? correct me if i'm wrong and how can i have more pwm maybe for software but i prefer it  in hardware thanks for answer and to take your time to read this

You are right concerning the UDBs. There are some (4?) TCPWM components available in a PSoC4 which you may use as 16 bit PWM.

Is there some overview by which I can see which components use how many resources? So that I can easily calculate if my resoruces are sufficient?

There are some places to read:

The "device selector" in PSoC Creator lists the available resources for each device.

Every component datasheet has a chapter named "Resources" which shows the requirements of the component

Lastly there is a resource meter tab on the very right hand side of Creator main window which shows (after a succeccful build) the amount of resources used for the current project.
