Hi,

I am working on PRE 6 version. I implemented 2D graphic.
Video of working version which presents new radar screen.

Hi,

new schematic + latest hex (from 3.10.2011) in attachment.
I use my I2c board about one year without any problems. Now with modified MultiWii 2.0

Hi,

sorry, I am very busy man these days becasue I make diploma project, mobiDrone OSD, Android RC control parallely.

But the application is almost complete.

Michal, are you still considering the new serial protocol, and if you do will there still be need for an adding extra code?

Hi,
when I implement new serial protocol so no extra code will be longer needed.

Hi Alex,

ok, I will try implement new serial protocol to OSD.

Best regards Michael

MichalM_sk

Today I make some changes in layout.

next I am planing implement Current sensor, NTSC support, I2C support, some changes in layout. Will be added gps speed, gps altitude.

Hi,
open LRS allow transmit serial data also, so it doesnt require a ppm injection only openlrs tx and rx module + bluetooth connected to TX.
But it isnt a problem develop bluetooth to ppm adapter for trainer port.

MichalM_sk

Hi,

LM1881 separate Hsync & Vsync of video signal for timing (line positioning), characters are stored in prog. memory of atmega. Pixel "injection" to video signal via spi interface of atmega.

Cool project but controlling over BT is quite limited in range...

Hi,

YES but if you use bluetooth module on TX side of OPEN LRS rc system (with wireless serial port) and serial port on RX side connect to Multiwii so the problem with a range is solved

Hello, after a long time I'm back in multiwii scene. I have had some health problems so my interresting about multiwii went out of me.

Hi, I developed new proximity I2c board for multiwii (compatible with arduino pro mini & mega boards) which contains 4x sharp GP2Y0A02 IR distance sensors for object detections and 1x Sonar Maxbotix LV EZ1 for altitude hold less than 6 meters. For altitude over 6 meters is used a Baro. Current s...

This firmware viewtopic.php?f=8&t=649&start=20#p3555 also works with serial GPS module.
Another multiwii config utility doesn't permit display GPS info currently.

MichalM_sk

Hi,

you use this version?

I am very interesting in linking OLRS with MWC on PPM and bi-di Serial. I am currently using OLRS made by myself , pdf plans are shared. I was wondering if RFM22B could be connected to the same Atmega 1280 controller, so i could develop a board with bi-di Serial and RC included. By the way, you bui...

Man I wish I had a friend who could make me those chips openLRS hardware and software (without two way serial telemetry, only rc control + ppm out + RX RSSI check ) can be found here m I have a homemade version of hardware, I did not want to wait until it comes from flytron:) All sources( serialLCD...

Hi, I need to see information from the MWC on my baseStation serial LCD, so I started the project for support two way telemetry.

Hi, ok i will test it. MichalM_sk Can you test if this works.? I dont have a shield redy for my MEGA yet so i cant test it. Trying to get it to run on a PROMINI. This small calculation will rotate GPS axis to compensate Roll & Pich To the compass heading. Add it last in void GPS_position_control...

I very interested in your GPS solution.
Can you give me your schematic and source for the GPS adapter board to implemt this in my MULTIWII Copter with Arduino Pro Mini?

thanks

Hi,

sources & pcb layout in my first post

Hi, I use Mtk3329 chipset ( Skylab SKM53 gps module) in my GPS to i2c board. It is a good module for a low price. Default config for this module: 1Hz refresh rate (up to 10Hz) NMEA sentenses On Baud rate 9200bps Configuration messages that I use for MTK 3329 chipset GPS module: #define SBAS_INTEGRIT...

Hi, m This is promised MultiWii 1.8 version with my addons. Added: MultiWii firmware: 1.GPS I2C Support for Arduino Pro Mini & Mega boards 2.GPS is divided into Serial(SER) and I2C in Config part 3.Position hold (should work on both not tested in 1.8 yet) - position hold is activated after the A...

MichalM_sk

Very good Alex. Within two days I added to this version of GPS i2c support for the Arduino pro mini. On integration of GPS can we work together. Hi Alex, You are fast just started same thing, by porting ardupirate code. For PROMini somthing like that should be enougth to read serail at 4800 baud, do...

MichalM_sk

Hi, I returned from vacation. Following days I will implement my code to multiwii 1.8 and then publish the source code. Info for all interested This project is built on the Arduino pro mini platform which has only one serial port. Therefore, communication with the GPS is solved through the I2C bus. ...

Have someone tested v1.8 with WMP + NK in level mode ?
Thanks.

Project status:

Position hold work (still needs a lot of testing) but i have gps unacuracy during the day sometimes up to 20 meters (in Slovakia, like elsewhere in Europe), about 10 - 11.00 pm only 1 to 2 m.

I have to try it when the geometry of satellites in the sky to determine the best accuracy.

Hi,

my idea is release parachute when in level mode MWC will rewind to 360 degrees or free fall.

This is almost a technical problem, program routine can be very simple.

Basic steps to safe MWC:

detection problem,
stopping engines
wait any time and release parachute

currently is implemented the routine to hold position and go home position (not complete - missing yaw correction)

I use custom i2c protocol, 23 bytes was sent only for visualization purposes in multiwiiconf, currently is addressed only 10Byte (4 bytes Latitude , longitude and 2 conf bytes), control board read data from i2c GPS every 100 ms. Reading speed at 400 kHz is now comparable to the HMC5843. Refresh rate...

MichalM_sk

Hey michalm_sk, Great, keep going. I check the details from the gps modul you are using. The positional accuracy is normaly 10m. Do you think there is a good position hold function thinkable? Greetings Kayle +- 10 meters is normal positional accuracy for non-SBAS (WAAS, EGNOS,...). but sirfstar III...

I added a new video with full implementation to MultiWiiConf.

Hey michalM_SK, Thats awesome. Really great. Where do yo come from? Did you think to realize a position hold with your gps code? Kind regards Kayle Hi, I am from Slovakia.
