@Pyrofer

I'm lovin' this little GUI unit!

I have a couple of questions:

1) How do you get telemetry data / MSP data into the unit?
2) What language is the GUI written in?
3) Do you have the source / software available somewhere? Google Code? Github?

Thanks!

@Hamburger

Where is the "updated wiki" for v2.3....?

Many thanks!

city_kid

Do you still have the source for this?

What hardware does it run on?

Why was it unusable???

I have ordered a 7" LCD Touchscreen from Ebay. I already have a spare Raspberry Pi with the MultiGCS image running on it.

I will put the two together soon and test the MultiGCS platform properly....

@kataventos I will probably publish my Processing code, once I've actually flown with it! Bear in mind that it needs a modified version of MultiWii to work... I like the look of your GCS, but have questions: 1) Is it running on Raspberry Pi...? 2) Did you know that Oracle have now released a "r...

@kataventos My Ground Station software is nowhere near as good looking as yours but I thought I'd show you what I have anyway! Ground Station.jpg Running on a regular miniITX PC motherboard.

@PatrikE

OK, that explains why there is no RCSERIAL define in config.h anymore...

Thanks!

city_kid

city_kid

@Hamburger Will RCSERIAL and all the usual MSP commands be available in v2.3...? I've downloaded and looked into the MultiWii_dev_2013_08_23_r1573_pre_2.3 version and I don't see the usual: #define RCSERIAL My control system is NOT a traditional RC TX/RX arrangement but instead uses serial MSP comma...

city_kid

@copterrichie Yes, I agree, Java is the main problem with Processing on a Pi. This is why I opted for Processing ontop of Windows XP (!) on a "regular" x86 motherboard. This allowed me to code easily in Processing, 'cos I'm I'm not that good at code. The problem with that solution is power...

city_kid

@kataventos This is AWESOME! I've been working on a big chunky Ground Station platform based on Processing, but the problem is that it's too "heavy" for the Raspberry Pi. So I'm using a MiniITX type Intel motherboard powered by a big 12v Lead Acid battery mounted in a case, but I'd love to...

city_kid

Excellent news! The only problem with the SZ05 module is a lack of RSSI or signal strength reading. Have you flown with it yet? What baud rate are you using? I'm running at 19200baud which seems to work very well... I would love to know how far it would go. I have my Hex setup with Return to Home on...

@eosbandi & anyone else... I've now got my MultiWii boards spitting out MSP messages for use in a Ground Station / Telemetry application.

@cocoludro

Please PM me your email address and I will send you some datasheets for the SZ05 module....

Cheers!

city_kid

city_kid

@cocoludro

OK, really easy then:

PC End: Use the SZ05 Eval Baord via USB
Arduino End: Direct connection to supply and TX/RX pins.

city_kid

city_kid

@cocoludro

If connecting to a PC, using the Eval board is ideal! I takes care of everything.

Then at the MultiWii end you can just connect the SZ05 module directly to the MultiWii Serial connector. It is already at 5v TLL levels.

Very simple!

city_kid

city_kid

@cocoludro The connections are really easy! On the Shuncom SZ05 module the four (4) pins that you need are all next to each other: [TX1] [RX1] [VCC] [GND] See here: Shuncom SZ05.jpg Pretty obvious: GND = 0v of supply VCC = +5v DC of supply RX1 = Receive Data to Arduino / PC TX1 = Transmit Data to Ar...

Has anyone tried MultiWii v2.1 or v2.2 with the new Arduino v1.5.2 Beta version?

Download link: http://arduino.cc/en/Main/Software

I've downloaded the new Arduino IDE for Windows 32 bit and it seems to work, but has anyone tested it for compatibility with MultiWii code?

Cheers!

city_kid

@scatterbrain You need the whole codebase (package). Download it, unpack it, and stick it somewhere different to your current MultiWii code. Then you can open the new code and the old code in Arduino and copy / paste the "config.h" settings from your old code to the new "config.h"...

Interesting stuff! So far I've tried the following: 1) Bluetooth(!) 2) NRF24L01+PA+LNA - 2.4GHz 200mW SPI with Arduino serial convertors: Work well! 3) HopeRF HM-TRP - 915MHz 100mW UART transceivers: Bad! Data delayed by long periods! 4) 3DR Robotics - These ARE HopeRF HM-TRP modules, so same proble...

city_kid

@scatterbrain Ok "modded by me" really means "configured / tweaked by me", sorry... I have also added a little code around telemetry reading, but definitely not this "//#define OVERRIDE_PSENSORPIN" section. The exact *starting* codebase I am using is from here: http://c...

city_kid

@scatterbrain I my codebase which is MultiWii v2.2 (modded by me) in the "config.h" file there is: //#define OVERRIDE_PSENSORPIN A1 // instead of A2 // Analog PIN 2 It's commented out in my config as I don't need to change the pin: I have an "A2" pin... Hope this helps....! city_...

city_kid

@scatterbrain It really looks like the board you have is orientated towards the Megapirate platform... I concur with Hamburger, and you should probably use the VBAT / POWERMETER pin overrides available in config.h On the subject of the Allegro Hall Effect sensors. Yes, I am currently using one of th...

city_kid

@scatterbrain Sorry, yes, the RCTimer sensor has got one serious drawback. There is no electrical isolation between the high voltage / high current LiPo battery side and the lower voltage / low current MultiWii side. These kind of hall-effect sensor have complete isolation: m You simply put the uncu...

city_kid

@scatterbrain @hamburger I can't get a good high res photo of the board. I can see some analog pins down the one side but they appear to start at A3. I think that powermeter reads analog pin A2 by default.... Are there any "pads" on the bottom of the board? Can you attach some very high re...

@crashlander

Great! So you've got comms between the modules?

I've just ordered another two modules from Shuncom. One for my new hexacopter and one for my ground station for direct telemetry....

@Hamburger

OK, I understand the specs, but where do you buy them from?

Amploc only seem to have their own *crappy* website!

Can't find any on Ebay!

Can't find a UK distributor like RS / Farnell / Mouser etc...

Please advise....

city_kid

city_kid

@crashlander OK, good! This is all correct. So when you see the first menu: Please select language -> Send a "2" to set English. Then send the word "SHUNCOM" to enable config mode. After that you should see a menu of different options like NetID, Node Type, Baud Rate etc etc . Th...

@cGiesen

OK, cheers for this information.

Maybe one easier question will help me:

When you use Baseflight to store a Waypoint, does the program call the MultiWii "MSP_SET_WP" command???

city_kid

@cGiesen I'm really liking the "cleanness" of the Baseflight Configurator GUi...! The "Holy Grail" for me now I have working GPS / GPS RTH, Stable flight, descent PosHold etc etc is to program an "autonomous" flight based on GPS Waypoints. Some questions: Question 1) Do...

@gompf-2 Sorry, but I thought that was a typo! My mistake. I've not seen this "FlySky" project, but the hardware is similar to one of my solutions. The RF transceiver modules that they're using are SPI interfaced like the nRF24L01+ modules that I am still using on my development platform. ...

@Andrej @copterrichie I've been testing out various homemade TX / RX / Telemetry transceivers.

@PatrikE Update and success! You were totally correct about where to put the code and how to execute it! I ended up with the following in the Output.ino "mixTable" function: // Experimental Code! if #define AUX4_TO_A1 then send any AUX4 value directly to A1 pin #ifdef AUX4_TO_A1 servo[1] =...

@PatrikE If I have the mod code in at the end of the mixTable function, surely it will simply set the servo[1] value to the AUX4 value...? At the very end of the "mixTable" function: #if defined(AUX4_TO_A1) servo[1] = rcData[AUX4]; #endif I am trying not to enable any of the existing CAMST...

@PatrikE So I've added this to the end of the "mixTable" function in the Output.ino file: #if defined(AUX4_TO_A1) servo[1] = rcData[AUX4]; #endif And in config.h #define AUX4_TO_A1 Could you tell me if this looks OK...? I hope it will map any inputs to AUX4 to pin A1... Thanks for your hel...

Is the table you attached here part of a bigger lookup table?

If so, where can I find it?

Something to translate the software variables / defines into "real world" pins / values would be really useful to me....
