Hi,
I did three documentations for the features I wrote/edited:

Hi, if you right click on the link you can download the zip file directly. Thank you for the feedback. 1. you have to define arm/disarm via sticks in the config.h 2. I don't know anything about the GPS code - sorry. About the results: If the failsafe landing is active, it is also in Level mode so th...

Hi, thanks to the fantastic reverse engineering of Mr.RC-Cam I coded the PilotLamp feature. This code is based on the stock MultiWii 2.1, so you have to make your changes as usual in config.h. There is a new define in config.h now: #define PILOTLAMP #if defined(PILOTLAMP) #define BUZZER #endif So if...

Hi,
just uploaded it:

Hi, I had some users here that had trouble understanding the buzzer function and the inflight acc function. As the programmer of a function one does not have trouble understanding how it works but all the users here may have problems activating and configuring some functions. So I want to ask if eve...

shall i zip them for u?

Hi, I included lost model buzzer since v1.8. If failsafe kicks in or you switch off the tx. The buzzer starts to beep every 2 seconds. I always use it if I have to land in high grass. I recently coded the same solution with the pilot lamp. I use GPS code.So I sometimes do nothing with the tx for abo...

I use a svn client called "tortoise svn" it is easy to understand and handy.

jevermeister

Hi, it is a bug introduced by a stupid user called Jevermeister If you want to have it clean and save memory do this: Find this in Multiwii.ino Lino 139 #if defined(LOG_VALUES) || defined(LCD_TELEMETRY) static uint32_t armedTime = 0; #endif and change it to this: #if defined(LOG_VALUES) || defined(L...

Hi there, I just uploaded the code to my branch of the google code SVN repository: http://code.google.com/p/multiwii/source/browse/#svn%2Fbranches%2Fjevermeister%2FMWC%202.1%20PilotLamp%20Beta%2FMultiWii_2_1 This code is based on the stock MultiWii 2.1, so you have to make your changes as usual in c...

jevermeister

Interesting idea.

I will have a look at that.

Nils

jevermeister

armedtime is declared if you enable telemetry.
so you have to enable telemtry to use this feature.

it is already fixed in the trunk moments after release of 2.1

jevermeister

So the pilotlamp is here. I coded some warning patterns and made the defines for all three boards. I want to test the implementation over the weekend.I need some volunteers for pro mini and pro micro and mega boards that test if it works. I am struggling with alarm patters right now. Nils ps.: I wil...

jevermeister

Hi,
I use a HXT 900 Analog servo and I am powering it from my Flyduino. The Flyduini is powered by one of my ESCs. (Mystery Pentium 25A)

If I throttle up the copter is starting to wobble badly but calms down after a few moments.

I am using stock YAW PID for a start.

Nils

jevermeister

If I attach a Servo to the Channel and leavi it alone on the table it is not shaking, I think it is a feedback of my mechanical gimbal.
I use the stock PID of 2.1.

However, the servo seems VEERY sensible to movement of the copter, I should lower YAW P - right?

Nils

jevermeister

Copying PID values won't help you.Every copter has his own characteristics, based on motors , props, esc and frame characteristics.PID working for my copter mwy not work for yours at all.

Hi, out of curiosity I revived my tricopter but having the supershaky rearservo again. If the tricopter is stationary on the table then everything is okay. But if I disturb the copter the servo starts shaking and it enters some kind of feedback. The same is happening inflight. Anyone has an Idea wha...

jevermeister

Hi, first of all: I know this is sound stupid but I believe it is a funny idea. I began my copter carreer with a Mikrokopter and I noticed that, the ESCs where arming in a funny sequence one after another.. I know they are on an I²C bus but may it be possible to achieve this effect on Multiwii? My f...

jevermeister

Yep I applid 98Hz lpf to it. I have some vibrations from the motors i could not get rid of.
it flies fine now

jevermeister

Thanks for that release. I just implemented my new GY-86 with MPU6050 and she flies great with stock settings. GPS Code is epic! The VT100 code really helps. All the small improvements are great.Also the GUI is getting better and better. Thanks to everyone who contributed betatested and reported bug...

jevermeister

there are different approaches to test the signal valid status: stick values between boundaries ppm pulse time valid heartbeat etc I tested some receivers and sum signal generators and there are quite some differences.If you have a scope, see what your rx is doing and implement it. One more option w...

jevermeister

Hi,
I will have to contact alex about that.We have a policy about that.
But I would be happy to merge them into a new file.

Btw. every Buzzer sound has to be managed by buzzer.h.

nils

jevermeister

Hi, I balanced everything as good as I could. The props are not the source of the vibrations, the motors are creating them. I use new bearings and new shafts but these CF2822 are s**t. But I use to crash very often because I try new s**t every day so it is too early to get new motors . If the LPF he...

jevermeister

Hi, I applied LPF of 155Hz and it got better. With LPF of 98Hz the result is now as eprfekt as before. (Is there a negative effect using the LPf) I can make flips like before, everything is okay. What difference does it make if I power the board via 5V? I have some troubles with the wires, my flydui...

jevermeister

Hi, I received my GY-86 yesterday and replaced my old sensor combo (WM+, BMA020, HMC5883L, BMP085) with it. I ran v2.1 moments before the sensor switch and had a perfect flying QuadX, I tested the GY86 today but now the copter is very twitchy. When I throttle up the motors start to twitch a little, ...

jevermeister

I am implementing it as we speak, my pilot lamp is still underway but the code is already integrated into buzzer.ino.
I will put it into shared trunk as soon as I tested it,
I implemented some blink patterns.

Nils

jevermeister

You say, you fly an object with 3 to 8 spinning sharp blades and do not know what it is doing if , lets say, the batteries of your tx are dead!? Sorry for saying this, but this is irresponsible... The behavior of failsafe is always the FIRST thing I check after including a new RX or a new software. ...

jevermeister

- Support for Pilotlight (I am on it)

- Pausing of GPS RTH or PH while doing a stick input

jevermeister

Do you have some news?

Nils

jevermeister

Eosbandi, I wanted to inform you,that my crasing issue was due to my new Buzzer code.I created a null pointer access that crashed the fc. So it was my fault. Sorry for the confusion. I tested RTH again today in slight wind and it is astonishing how well it works. Only drawback is the missing visual ...

jevermeister

Hi, Yep, both of you where kind of right. First of all, letting icnt getting bigger than 3 was a bad mistake But the reason why the code crushed was this: patternInt[icnt] = something; if icnt >3 the switch case can handle icnt >3 (I tested that) nevertheless my code was very wrong so I fixed it acc...

jevermeister

Hi, I recently programmed a new buzzer code. I used chars to define a beep pattern. However, the following code semas to lead to a crash, if I try to enable GPS RTH or doing wild stuff with my copter. I only can reproduce the reinit of the Mega if I enable the buzzer code via define buzzer. So I cha...

jevermeister

Hi,
I had a reset issue with the newest buzzer.ino.

I will revert the changes.

Sorry for the extra work

Shame on me!

Nils

jevermeister

Just a short update,
I ve flown with my improved Buzzer.ino that uses chars to transfer the duration of the beeps and a switch case subroutine.
I // the define of buzzer and vbat and the problem seems gone now...

I think I created a memory leak !(?)

Nils

EDIT: will try wingui in a minute

jevermeister

Okay, jsut did some backyard flying moments ago, and the controller reinits if I enable mag mode or GPS (mag mode also enabled). It is not doing this everytime but mostly... The first occurance when I armed and gave a lot of throttle. IF mag mode is enablesd and I yaw the captor ahrd by hand it is a...

jevermeister

I had the weirdest issue today. I tested Coming home again today and hat slight wind from west. ... f I switched it on while it has to fight the wind to rth it was twitchy as hell and flying circles and tries to run away. Sounds very much like: http://www.multiwii.com/forum/viewtopic.php?f=8&t=...

jevermeister

The mag is the problem here, because of the wind the copter has to tilt more and the mag is causing the copter to get fuzzy.

The RTH wroks great, it tries to accelerate more against the wind - behavior is expected.

Nils

jevermeister

Isn't there a heartbeat signal present? You could definetly include that into I2C GPS Nils I2c gps has this feature, when no GPS signal is detected for 1 sec, then it will ouput NO fix... so I just have to port this to MW serial GPS code.... OK - Nice to know you are alway prepared Andras . I had t...

jevermeister

Isn't there a heartbeat signal present?

You could definetly include that into I2C GPS

Nils

jevermeister

Andras,
can you sum up the parameters for GPS`? The thread is quit long.
We should update the FAQ ASAP, I will contact Alex for this.

Nils

jevermeister

Have you tried the EEPROM clear thingy mentioned at the beginning?

The board of my friend is broken too but is doing nothing sometimes - but this problem is super strange.

Nils

jevermeister

yes the orientation on the gui is correct following all axis manual pitch forward - fights back manual pitch back - does not manual roll left - fights back manual roll right - does not **note all esc's have to be re-calibrated by manual - you mean with the hand, that is hoding your copter? so if yo...

jevermeister

Okay - got your mail. Nothing has been changed between 2.0 and the dev you are using. The config.h seems correct to me. When you connect the copter to the GUI and tilt it in your hand (motors off) does the copter move correctly? Tilt it to left copter in gui is doing the same? same for front etc. is...

jevermeister

can you send me your config.h per mail?

pm me for the adress. I want to see if there is something wrong.

Nils

jevermeister

If the motors are switched the copter would not hover a splitsecond and wobble to death. It is strange if you say, that that the channels are shwon correctly in the gui but the copter behaves different. At firs I thought of wromg channel connection but then the gui should show that. If the motors ar...

jevermeister

Dan,
if you pitch front or roll left is the copter doing it too?

It is important to know if only inputs result in reversed movements or the correction done by the sensors.
I know you already checked it but it sounds like a switched motor connection.

Nils

jevermeister

I just had an idea for the RESET of home position. Why not using the same switch as the switch for RTH activation but only when motors are not armed : if (rcOptions[BOXGPSHOME]) && !armed) { GPS_reset_home_position(); } I think the gyro init is good enough.and it is a trigger not a switch.

jevermeister

Alex,
there is no beep after writing params from Conf to EEPROM.
But if I understand the code correctly it has to beep. It is using blinkLED like Gyrocalibration and AccCalibratien etc. And they all buzz.

Nils

jevermeister

Andras, as stated by you and as experienced by me: If you hold the copter while it tries to return home it will become more and more aggressive because it wants to speed up. Because of the bad thunderstorms tonight I haven't got the time to test (thanks for your PM - I suspected the mag too.) Imagen...

jevermeister

Hi, let's try it step by step: Read the FAQ here: m and especially do the tests described under "How should be the sensor axis directions" Maybe the board is reversed. Or the sensor orientation in the code is wrong. Report back if you have done that. Do not give up mate - the problem seems...
