is it possible to use MSP via i2c??

like sending and getting commands via i2c instead of the usb or serial cable?

alduxvm

Sorry to awake this old subject... I have a question regarding MSP with naze32... So, in order to do the rc override, I need to do "set serialrx_type=4", once I do that, the standard RC does not work anymore, if I want to switch to this radio I need to "set serialrx_type=0"... fi...

alduxvm

That worked great Marc!

Thanks a lot!

alduxvm

Hi! I have an Afroflight Naze32, being configured with the awesome chrome GUI... everything standard and it works and flies excellent using my radio. I fly in a motion capture lab, and I send commands via a telemetry modem to several other multiwii boards, like the AIO pro from HK... like in this vi...

alduxvm

totally true!

thanks a lot!

I knew about the GPS... I'll post the logs to see if 18000 is actually true haha

alduxvm

Thanks a lot Patrik! that worked very easily! After some tests, I end up using this one instead, based on your structure: #if defined(CAMTRIG) #define OPEN_HATCH 2000 // µs #define CLOSE_HATCH 1000 //Small altitudes just for testing #define OPEN_AT_ALT 50 // cm #define CLOSE_AT_ALT 150 // cm // If a...

alduxvm

We actually just need a servo to move to 90 deg and then close when the altitude is appropriate... This is the one I want to modify: #if defined(CAMTRIG) // setup MIDDLE for using as camtrig interval (in msec) or RC channel pointer for interval control #define CAM_TIME_LOW conf.servoConf[2].middle s...

alduxvm

Hi guys! What would it be the easiest way to open a servo payload tray at a certain altitude? I'm using a multiwii board (HK AOI) with a openlog to log GPS, Altitude and Attitude of a system that is going to go inside a high altitude balloon... and at certain altitude (25,000 meters) I want to open ...

Alright guys, if someone is interested, here is a better-shorter version of my code, for you to try, and also a small video for you guys to see it in action:

ok, I made lots of modifications and finish up doing a new project m there you go guys... on my mac I'm getting data at 62.5hz... it looks like this: {'gz': 0.0, 'gy': 0.0, 'gx': 1.0, 'ay': -20.0, 'ax': -22.0, 'az': 520.0} 0.016 {'gz': 0.0, 'gy': 0.0, 'gx': 0.0, 'ay': -22.0, 'ax': -17.0, 'az': 513.0...

alduxvm

Ok, I manage to do the first part!!! My objective was: - Custom MSP for sending the first 4 RC channels and ACC and Gyro data - Receive it and process it as fast as possible, at least 50hz How I solve it: - I had to make some changes on the MW code, just add a couple of functions to Protocol.cpp and...

alduxvm

Thanks Marc!!

Is there a modification on the MW code for this tests?? or everything is on the "reader" side??

also, in the second part, does your function "askMsp" clears (flush) the serial port?? and do you put a sleep or small delay on it???

alduxvm

Good day everyone!! Let me tell you a bit about my project, before I start asking questions and suggestions As the subject implies, I doing systems identification of multicopters being flown by me via a multiwii board. Why do I want to do this? I want to do very precise navigation algorithms using a...

here is some update guys, a video I did:

My mistake!!!

I was just plugging in 4 cables... vcc, gnd, tx and rx... but we need to plug all of them, even the DTR and CTS...

alduxvm

I'm trying to upload this on my openlog, but so far, it has not being possible... So, what I did is this: - I have a FTDI cable, connect the board to it, and crossover the tx/rx - Download the firmware, and compile/upload it and so far, I always got this error: avrdude: ser_recv(): programmer is not...

alduxvm

Thanks a lot, I'm going to test Renes firwmare!!

alduxvm

Sorry for taking to much replying on this post... I havent tried Treym's solution yet... Im using now MW dev 2014 with the modified pid's algorithms and I'm getting better results, I'll post when I had something interesting to post Meanwhile I'm going to try to use openlog to do some system identifi...

alduxvm

Has someone implemented datalooging with OpenLog with MW dev 2014 by any chance?? I'm using r1648 and it would be really uselful if some point to me where to insert the code?? maybe in MultiWii.cpp??

And also, I have to put the openlog v3 firmware (https://github.com/phollands/OpenLog/tr ... OpenLog_v3) on my virgin OpenLog??

alduxvm

ok, and dummy question... how do I activate throttle_angle_correction?? hehe

alduxvm

No extra wind that I'm aware off... Im in a indoors lab, maybe some small turbulence created by the air flow hitting the walls?? maybe that... and also ground effect was a issue at the beginning, we could even hear a very clear difference between certain heights and ground effect... Ill try those se...

alduxvm

mmm, maybe no the pid's, I just want the board to be quicker, to "fly" quicker, more responsive... so, i was playing with the mid, expo for throttle and rate, expo for roll/pitch... is there another way to make it faster??? anyhow this are my specs: - 5x3 props - turnigy sk3 2110 kv you ca...

alduxvm

Hi! Im trying to modify the PID's of my small 3d printed quad, that is being controlled by a computer... So, my setup is as follows: - Small 3d printed frame - MW AIO board, 2.3, no changes to firmware - 3DR modems for communication with GS, with Sik-Mw 2.3 firmware, 115k serial speed - Using MW ser...

alduxvm

Thank you very much EOSBandi!!

I can confirm this firmware works on the original 3DR modems as well in the HK clones!!

I'm using this ones:

alduxvm

Actually... how did you flash them???

alduxvm

Do I need the SiLabs debug adapter to change the firmware on the radios??? forget that question... Im uploading the firmware with the python script, but I have a error, have you ever encounter this one?????: rdg_mac:Sik-mw-2.3 2049632v$ python sik_uploader.py --port /dev/tty.usbserial-AM0264PU radio...

alduxvm

I still have the latency problems, I'm trying now with a BT radio i have and after one minute of being on, it start working nice... so, I'm going to use BT... and i just bought a couple of nRF24L01 with a UART interface, so I will try them as well...

Cheers!!

alduxvm

Hi!! I'm controlling a MW board from Matlab/Simulink, I can send the RC commands and receive the attitude reading, with the USB cable plug in, works excellent, of course, but I need to have wirelessly... I tried to just plug a 3DR radio on each side, and I get a super super lagged response, I know t...

alduxvm

ok, it appears we are working on the same, care to chat??? alduxvm at gmail, write a email and we can start from there, when we get results, we can publish them here

cheers!!

alduxvm

is no possible to test your scripts @crashlander??

i would like to test this: https://code.google.com/p/mwii-msp-tx/

cheers!!

alduxvm

This are some flights I did with the modifications to be more fast

How about that??

alduxvm

ll make a video and upload it

Cheers!!

alduxvm

I removed all telemetry data and the rest of the data thats send/received, and only send the RC commands, and I did my first flight right now

I just need to modify a little bit the rate, expo, mid, to be able to fly it better, but is working!!!

alduxvm

ok, i manage to put it to work, using mac, procontroll and processing 1.5... MW 2.2 (on quad) and the MW config that copterrichie give me I did two tests, the first one, was using the usb cable, this one works excellent, very quick response, but of course I cannot flight because of the cable. The se...

I'm having a wee problem...

"Cannot find a class or type named "Slider2D""

mmmmm, strange because controlP5 library is correctly working...

alduxvm

wow!! thanks a lot!! ill post my code as well and maybe a small video

Cheers!!

I'll start making this using processing...

alduxvm

Hi all!!! I want to control the MW from the computer, why?? because I have motion tracking cameras, and I want to perform some navigation algorithms, my idea is to have on my computer a 3DR radio or a Xbee or even a BT adapter, and another on my quad, and just send the commands to it. I've been read...

alduxvm

Hi!! How are you?? I want to do that as well, have two ways of controllling the MW, one with the normal radio (turnigy 9x) and the other via the computer (maybe BT or a 3dr radio), what do I require to do that?? I now that I need to write some code to make the serial protocol on the computer side an...
