Hi.
I downloaded the example, ran it and it works. However, I have one concern about the program.According to the program description there should be a signal on the GPIO14 OUTPUTXBAR3 output that reflects the trip signal (J8 74 or J8 72 - it depends if you search by OPXBAR3 or GPIO).
According to the program description there should be a signal on the GPIO14 OUTPUTXBAR3 output that reflects the trip signal (J8 74 or J8 72 - it depends if you search by OPXBAR3 or GPIO). On the GPIO15 output EPWMB (J8 73).
In the kit documentation it says EPWM8B on GPIO32 (J8 71). OUTPUTXBAR3 is located together with GPIO26 (J8 74).
And the program itself works with the setting:
EPWM8B - J8 73
OUTPUTXBAR3 - J8 74
A question strikes me, is this a documentation error or a program error? As I wrote, the program runs and works for me, but I treat the thread as a place to report a noted bugs.

Hi Kacper,
Thanks for bringing this to our attention. The example code is configured to bring out OUTPUTXBAR3 on GPIO14 and EPWM8B on GPIO15.
If you are measuring EPWM8B on J8 73, that is correct because it's GPIO15 on the Launchpad.
However, I am not sure why you are seeing OUTPUTXBAR3 on J8 74 because that is GPIO26 on the Launchpad. Can you double check your setup to make sure it's not J8 72 you are measuring.
I found a bug. It turned out that the "Quick start Guide" paper was in the old version at my place and the pin numbering errors have already been corrected in the new C revision.
