RE: [Paparazzi-devel] Route PPM back to RC receiver on tiny2_1_1

[mark.griffin]

Hey Andre,
If you want to directly drive a receiver which has a microcontroller
that does the decoding and driving of the servos (not a 4015 or 4017
decoder chip), then you need to use the "servos_ppm_hw.h" file. 
There is some recent info on the Wiki at:
http://paparazzi.enac.fr/wiki/Airframe_Configuration#Radio_Control
Hope this helps.
Cheers, Mark

Hi Andre

servo_direct is not meant for that. It's meant to produce a ready to use
servo pulse ( 1-2m/s high , period 25ms) using the PWM hardware of the
LPC What you want is really servo_4017 or servo_4015 depending on the
driver in your receiver and configure that code for the wiring of the
tiny you're using.
