MultiWii

I don´t think thats a problem with GPS/Nav I see these possible Problems: - Software error due to number overflows in my code / the MultiWii RX PPM Code - Noise on the PPM Channel, so the Chip misses some flanks / triggers when there is no flank. - Problem with generation of PPM Signal in Receiver (...

did i post in the wrong subforum? How do i get this merged?

Why not? Just use Timer Capture Events with a unused Timer . Guess the load should be ok. Another way would be to add a additional avr, that only does Serial I/O and interconnects via ISP.. However if you want to talk to the main Atmega, you will have to do Interrupts again, which should lead to the...

Hello i fixed this, see my patch: viewtopic.php?f=8&t=4788 or my blog: https://www.spacefish.biz/2014/03/ppm-m ... io-pro-v2/

I know this Thread is nearly two years old.. But i created a Patch that adds this functionality, as i had the problem myself: viewtopic.php?f=8&t=4788

You are limited to some pins in the current software, as you can only use pins that generate a interrupt. This is due a hardware limitation (not all pins generate a interrupt). Another way would be to use the ICPX pins (ICP1-ICP5 on Mega 2560). But you have to change the code / initialize the timers...

sorry for adding this as 7z, the Forum software told me that extension .patch is not allowed.. here is the .patch inline (for fast preview) Index: MultiWii_shared/config.h =================================================================== --- MultiWii_shared/config.h (revision 1664) +++ MultiWii_sh...

Please see attached .patch file.. Some new Boards use the PL1 Pin as PPM Input, as it can calculate the timediff between pulse very accuratly via a timer and is hardware filtered (to filter noise). In my patch i did´nt use the counter, as we have to handle overflow and such, but used the normal rout...

I use the new PID implementation. Acro mode works pretty well for me, however i can´t get angle nor horizon mode to do anything, i played arround with the pids for level activated / deactivated the modes, but the quad just behaves like acro-mode no auto-leveling at all. ACC is calibrated and works (...
