FYI -- there's a typo in chapter 5 of the guide for the CY3214 kit involving the port/pins to be used for the feedback resistor.
On page 39, the CSD Wizard global settings shown in fig 5-12, shows that P1[1] is to be used for the feedback resistor.
On page 48, in section 5.1.4 "Verify Output", the instructions say to connect the 2 kohm resistor between P0[5] and P1[5].
One terminal of the feedback resistor MUST be connected to P0[5], the other terminal can be assigned to any available pin by the designer (within hardware constraints).
The "quick fix" - if you don't want to reprogram - is to simply connect the resistor between P0[5] and P1[1] as was set in the CSD Wizard. The moral really is that the pin you set for the feedback resistor in the CSD Wizard has to be one of the pins you actually connect it to in real life.
BTW -- a standard value 2.2 kohm resistor (5% tolerance) works just as well as the non-standard 2 kohm resistor described.
TWO HOURS to find this. I thought for sure that the capsense buttons on my kit weren't working.
So, how do I get this info to the proper Cypress authority so this error can be corrected?

I am afraid that there is not a typo, although it might be a bit misunderstandable. Figure 5-12 shows the DEFAULT settigs that you get before you modify according to fig. 5-13 which clearly states the pin for the resistor is p1[5].

Yes, but there are some stale screenshots that are misleading.
@SQ -- Also, sorry for the 2 hour delay this had caused!

Yes, Arvind. Any information that could be mis-leading should be avoided or corrected particularly for us non-native English speaking aliens .
We have a proverb here in Germany:
"When you have to connect two different wires to two other wires the probability to do that wrong is exactly 50%.
But this 50% are exploited to exactly 100%"

Egg on face!
Bob is right -- there is NO typo -- I was just too willing to let it be someone else's fault (i.e., not my fault).
When I was doing this project the "first time", the entries I made in the CSD Wizard "didn't take" -- dunno why, maybe I hit cancel instead of ok - whatever. I'll bet money that when I went in and redid the CSD Wizard entries I "skimmed" the instructions and missed the P1[5] instruction step.
Thanks to both of you for your understanding!
