    Hello, I'm very new to all of this can I ask a very basic question?

    cypress_3367771

      I have acquired a couple of PsoC pioneer kits (4 & 6).  It's been years since I've done anything with native code but it's coming back to me.  I have a question that would help me understand what is necessary from a design perspective and what is not.

       

      In PsoC Creator, let's say I'm doing something as simple as dragging a digital output pin onto the top design sheet to connect to an LED.  All of the examples I can download have a resistor and LED populated on the top design as well with values set for the resistor's ohms.  Take the PsoC 6 GPIO example 220263, I can see how the inclusion of each pin on the sheet is the impetus for the generation of build files to support that pin and register mapping of it on the pins interface.  What I don't understand is what if any effect the inclusion of the resistor and LED symbols on the top design have.  Is there any actual change happening in my project or programming of the board?  Are those just there for the reader's sake or do they actually support something?  I could obviously wire up any resistor and LED I choose so the 10k value for R3 seems arbitrary.  According to the schematic, there's a 750, 270, and 330 ohm resistor on the onboard RBG LED respectively, so I'm not sure what's going on there with the use of R3 in the top design.

       

      Thanks and let me just state that I didn't think my profile name was immutable when I signed up and/or that I'd be participating in the forums down the road with it.
