F303VCT6 (F3Disco) RC-SumSignal Read via PWM Input

Hello there,

i´m trying to read a rc receivers sumsignal via the PWM input feature. I just took the FW example and changed the ISR routine by placing the "TIM_GetCapture1(TIM2);" value into an array corresponding to a counter which is set to zero when a longer pulse than "x" is read.
It´s a 7 channel signal, but when i try to read moren than two, the sw "doesn´t work".
If i read a single channel signal it works perfect.

I guess i´m not the first one, trying this (allthough i couldn´t find someone else, only a solution for a read of four single single signals). So may be there is a detail in the configuration or in the principle the PWM input works, that i´m missing.

best regards!
