[Paparazzi-devel] Future developments of paparazzi

I’m trying to adapt the Paparazzi auto-pilot to a 4-motor VTOL plane : it looks like a V22 Osprey, but with 4 motors, but I have 2 problems :


First, I need at least 7 different outputs for my servos/ESCs, and I don’t want to use the camera-dedicated servo outputs of the Tiny 2.11. So I tried to figure out whether it would be possible to add more “conventional” servo outputs, and it seems that the CD4017BPW Decade Counter/Divider has 10 Decoded Outputs, which would allow to deal with two extra servos. But I’m not sure the code could deal with it (especially because it seems that the PPM input only allows 8 inputs – at least for now). What do you think of this problem ?


Then, I’m trying to find an inertial measurement unit that I could connect to the I2C bus, and I read on the wiki that you were working on it. What’s new there ?


Thanks by advance,


Antoine D.
