eCAP capture PWM example won't work

Roland Keller
Prodigy 60 points

Hello,

actual I am using a PiccoloControlStick with F28027 Controller. A lot of codes samples TI provided are working.

But now I have to use the eCAP Module to capture PWM.
There is a example in version 1.26  (sprc832.zip)  named "ecap_capture_pwm".
After compiling and target load with Code Composer Studio 4, the testsignal at pin 19 is beeing generated.
But there is no reaction to the signal edges if it is connected to Pin 15 (capture function)

This can be verified, if you are observe the variables "ECap1PassCount" and "ECap1IntCount".

Does anybody have the same problem, or solved this already?

 

Thanks a lot,

Roland
