Re: Arduino Uno connected to MultiWii v2.5

Youre creating a soft serial at 115200 baud? Good luck with that.. thats probably why its not working.. use 'Serial' to transmit to multiwii, then use 'Serial1' with an extra usb-serial bridge at 9600 baud (or something) to display it back to you. Or get a MEGA... or even better, rather than using '...

Re: Crius AIOP V2 with data logging IC

If anything it could be used to record telemetry, so that if it goes down unexpectedly you can 'go through the logs' to see received commands and motor outputs.. how many times have you walked from a crash and pointed a finger at the FC rather than anything else, that would at least prove the case (...

Re: Naze32 hardware discussion thread

Which rev board are you guys running? Did you try the cli setting emf_avoidance which overlocks the naze32 to 84 mhz (assuming a 12mhz xtal for the rev5) set up for this reason . Older revs overclock to 80mhz I believe with an 8mhz xtal. Good shout didn't see that, i'll try that too! I think that t...

Re: Naze32 hardware discussion thread

elmtree I had the same problem with the twitching outputs, checked the naze32 with a scope and found out that there's no jitter on the ppm input, but the motor outputs are jerking when the rx (hawkeye in my case) is close to the naze32. It seems the naze is getting swamped by RF interference from t...

Re: Problem in controlling a servo

You can't use the Servo.h library! That library uses a 'timer' which multiwii uses for the motors, so what youve done there is ruin the motor control timer by trying to control 1 servo. Because multiwii is meant to have many inputs/outputs they have designed the software to take that into account, s...

Re: PPM passthru for sending nav to other FC?

There are probably very few naza trolls here because its a specific MultiWii forum (not a generic multicopter forum).

Re: PPM passthru for sending nav to other FC?

What flight characteristics do you like about the KK2? I've used both and the multiwii is far far more responsive so rather than hacking together something like that, could you not tune/check how the multiwii flies to get it more like the KK? Also the current code doesn't do that (nor will it ever) ...

Bad serial link with 2.3 & SPEKTRUM SATELLITE

Hi all, With version 2.3 (official and latest dev build) I am using on a 328p with brushed fets. The issue I am seeing is that when "#define SPEKTRUM 2048" is used the serial link will drop 50% of packets and so become unconfigurable! The gui then updates at about 1 fps.. Here is what I us...

Re: ARM via MSP

What about if you lost serial connection? (eg software crashes sending the commands) You'd have no way to disarm it which would not be fun! Having it as a switch means you can manually override the setting with a standard TX should it get into trouble (safety!).

Hi, 5. Using oscilloscope, when disarmed the waveform is ~20% ON (normal - looks like its at 'MINCOMMAND 1000') not really normal: disarmed means signal = 1000us => at 490Hz, the waveform should be around 50% I would start investigation here I agree with Geebles observation.

This applies best to the MEGA because of the ability to use an internal 1.1V and 2.56V reference, the 328P has only 1.1v ...
