I also want the RSSI to be used in rushduino /minim OSD :

#define MSP_RSSI 121          //out message 1 byte RSSI in percent value

Here is a sample video of this OSD capabilities http://www.youtube.com/watch?v=lkAXFUaCtMc (i changed the video to a better example as some members suggested)

Thank You

I am unclear about new calibration startup procedure: 1-After PowerUp MWC, is any clue that AccZ calibration, giro calibration and baro calibration ended succesfully? 2- If we calibrate manually giro, yaw left- throttle down- pitch back, any other calibrations are made? How can i be shure that senso...

Regarding RSSI, the FrSKY offers RSSI on pin2 as PWM. Do i have to filter it out through R-C filter or it accepts PWM directly?
Found a tool to calculate RC filter here http://sim.okawa-denshi.jp/en/CRlowkeisan.htm

How about letting the Home and Hold point as is and create another point?

Hi, i soldered the ground bridge, here is the picture: I bought this OSD from here (m) Now, after uploading the code, the screen remains clean , as a direct connect with camera. Hi Dragu, You did not swoldered what I said on previous post. No need to solder PAL jumpers, and you forgot to solder the...

It would be a nice thing that MWC minimosd to use the same characted map as arducam, and why not, to use the same algorithm witch draws Artificial Horizon (works better on Arducam)

Hi Kataventos, I did those snapshoots from my update procedure especially to be used in a tutorial later, SO FEEL FREE TO USE THEM.
As an ingineer i really ned the osd schematics to figurr out what voltages should i have on max7456. Any pdf around?

albertoLG wrote:dramida, are you feeding both 5v and 12v to the osd or closed the jumpers as I told you? if not then it will never upload the fonts...

But why?
I will try to put back arducam osd software without 12 volts suply and if it works, it means i don t have to put 12v.
Thank you for your answer.

1- I modified MAX_7456_Font_update.ino only this snippet of code #define MAX7456SELECT 6//10-ss #define MAX7456RESET 10//10-ss In MAX7456_font_update.ino the commentary states 9600 baud: // MAX7456_font Sketch // at 9600 baud it take about 1.5min to download a mcm file // http://www.maxim-ic.com/too...

Yesterday i flew about 1.5Km away with R5 release of NHAdrian. It worked fine. I also flew R13 but in but in visual range. I'll update my fpv multirotor platform to r13 this week.

Eizo, this is an amazing feature! I want to test it and video-document it. Thank you! I wonder how can i increase the radio range of BT device from my phone to cover more distance. Actually works about 200m arond me (i tweaked CRIUS BT antenna with a 3 cm wire and i am using Galaxy S3 on ground). If...

I am curentrly flying FPV with MultiWii over long distances ( about 1-2 km) for aerial photography. I can tell you that RTH, position hold and Auto-landing is reliable for this purpose. (ps. autolanding and failsafe rth with autolanding is a newly implemented feature from NHAdrian, see http://www.mu...

It is exactly what i did, except that i modified Max7456_font_update.ino the way i read in this topic here:

I am stuck in uploading character set in MAX7456. Could anybody explain the "trick" behind this? What is all about in a engineering manner? I am trying to find font_update.ino with no luck. After uploading this sketch (wich i can't find) i want to use ArduCam to upload mcm file. Is my plan...

Adrian, it would be useful to "beep" like rcoptionsbeep when in AltHold mode, you change the state (climb, descend, hold) because you will get feedback, even in fpv.

Here is an international online shop wich sells ready-made drone solutions for aerial videography and photography based on multiwii controller.

I own the shop.

I was thinking buying this GPS( Ublox neo6M with eeprom) with this convenient shape but it costs 36 $ with the same electronics than 21$ from HK:

I saw some original arducopter minimOSD artificial Horizon videos and i observed that the horizon line works smoother on Y axis with more intermediary steps between on tilt.

Please consider that mid point for alt hold is 1500us for throttle, regardless where your copter hovers. If you like to hold altitude in a undefined position of your throttle, you should comment this line: #define ALT_HOLD_THROTTLE_MIDPOINT 1500 // in us - if uncommented, this value is used in ALT_H...

Here is how it flies R13 with Crius AIOP m Last edit: I activated RTH function with altitude control during RTH. I found out that copter starts moving immediately twards home, even the RTH altitude is not achieved. Practically, before reaching RTH altitude, the copter makes about half of distance ba...

It is not so difficult to solder one thin wire on top on the chip and then put some epoxi glue over it. You need an 8-10 watt soldering iron and a good eye. Please write a RSSI routine with calibration values for this analog/pwm approach firstly, and later, after a proven usefoulness, we could imple...

I know that MinimOSD with your conde can show rssi info from Multiwii serial stream, but how can I read and measure the rssi signal from the DR8-II. I have got a CRIUS AIO PRO and MinimOSD working together thanks to your code and I see ON screen the vbat voltage, GPS data ... But want to see also t...

dramida

Hey, wellcome back. I don't have complete expertize in this field but some ideeas : If we integrate acceleration, we get speed (You remembered me that one from alt hold ) . So we do another PID controller witch tries to keep speed = 0. If the PID parrameters are well tuned, it should not oscillate. ...

dramida

We all know that using IMU to improve GPS pos hold is already working in various controllers and has a great impact on accurateness of PH . The idee is that, long befor the gps can sense the positioning error, the accelerometer can sense if a lateral (X-Y) acceleration occur and counteract it by lea...

Adrian, in latest MWC R13_complete, in config.h, confuses me: I might be wrong, but i see two sets of configs regarding RTH: firstly: //#define FAILSAFE_RTH_MODE // if GPS present and ready, copter starts RTH when signal lost. When signal is back, control is back again. #define FAILSAFE_RTH_VARIO 10...

Hi Adrian, any news about vario altitude mode and auto-landing? Can we put a new release based on your work? I built a new dji style quad and i am ready test some landings

Ubiquiti XR9 XtremeRange 900MHz Embedded Radio module together with Raspberry PI has the power to revolutionize video downlink among other avatar-like features. Let's hope some smart people will see the opportunity and actually do it.

dramida

He used brushless motors in order to be able to control the magnetic thrust vector by simultaneously powering all 3 coils (i guess). I also want to know more details about how controller realize in witch position is at start-up.

H264 webcam + Arduino Due + ???? = Profit! That would be an interesting case to study. But we still need a DSP at receiver end. It would be nice to use the same device for transmitting and receiving. Also we have the advantage that for PAL/NTSC standard, we need half computing power than 720p. Othe...

I know this digital solution has some drawbacks but 1 s delay is huge. I expect some delays, but not so big. Moreover we need positive smart people who can tell us how could be done in a resonable manner. If you watch the movie above you will see that some folks already did it but the price is huge....

One thing that could revolutionize drones is a reliable high quality video link.

I am impressed with Rushduino versatility. I have a minim OSD and i want to program it with Rushduino.

Thanks Adrian You wrote that between ALT p and PIDALTP and consequently I and D, there is a corelation that in my mind shouldn't be as there are two different loops: Inner P-I-D loop controls altitude through Baro and AccZ as inputs Outer P-I-D loop regulating speed of altitude variation corelated t...

I don't belive in magic

To further test your code, i need to understand how it works, as a principle.

Adrian, i am no coder, please give me some guide lines on how to setup VarioPID's.
