Re: [Paparazzi-devel] PPM input Port

[Jochen Rieger]

Now, I am confused. In the wiki is written that the primary receiver input port is UART3.

Why is the Trig. Pin the input pin for PPM? I thought PPM -> Rx pin.



I want changed it because I thought UART3=PPM, but i have GPS on UART3.

Thanks for helping.

Hi Jochen,

If you want to use a PPM  receiver on Lisa, you currently can't change
the input pin for the ppm sum signal input.
It is hardcoded to UART1 trig (PA.01) pin.

Why do you need to change that?

Cheers, Felix
