Remzibi OSD integration with AH and OSD PID seting

[dramida]

This is a way to program MWC directly on OSD, and also have Artificial Horizon.

More details about the setup here.

I tried to emulate the setup but it's not working. I am using Ardu Mega board with a custom made shield and Renzibi OSD v1.1 I conected the MWC TX through an 1K resistor on T1 pad of the OSD but the horisont refuses to apear. I am using 1.8patch2 version of mwc and AH2.22 OSD soft version.

I found out the solution:

Remzibi OSD needs an serial imput @ 38400 baud with following comand strings:

Code: Select all

$CLS<CRLF> - clear screen
$SH<CRLF> - Save Home
$I,roll,pitch,<CRLF> -Artifical horizon
$M,x,y,L,E,text,<CRLF> - custom text dispaly at any x,y location with Leading and Ending symbols

So MWC software should use a spare serial on mega boards to send $I,x,y commands to the OSD.
For atmega328 configuration, a software emulated serial could be the only option to send the data to osd, or to reallocate the hardware port until the GUI is sensed.

or you could trigger start/stop of remzibi-osd-mode via stick combination. I did that for automatic switching between various telemtry pages. Search for auto_telemetry in multiwii.

Once it works, we have the benefit to use the OSD as another LCD type to do configuration, very good.
Now if all OSD firmwares' developers could agree on a standard command set to talk to OSD...

i love the idea of using the sensors already on board for osd, there is no point having two of everything.
What about using somthing like the MAX7456 http://www.sparkfun.com/products/9168 and using the arduino to power it? once gps is integrated you'd have everything. just a matter of the available ports at this stage i guess

Thank you Remzibi for doing a great OSD and Luca (gtrik) for mooding the mwc1.8p2.
Artificial Horizon (AHI) is a great tool for level mode IMU debuging because you see what the mwc IMU feels.
This is a FPV night flight with MWC 1.8patch2 and remzibi OSD AHI 2.22

Hi,

Is this modification will be integrated on the next release ?
for informations the source code is here : http://www.rcgroups.com/forums/showpost ... ostcount=1

Nobody here have taken a look over the Rushduino OSD post

its exacly what Cardboard says, a Max7456 packaged to work with arduino and multiwii code

Would have made more sense to simply improve remzibi code instead of redoing basically same hardware, amirite?
I guess duplication of effort is nice to do.

Rusdino looks to be a great product but I have promi and I need a GPS

I have good news, here is an RCGroup discussion with Mr. Remzibi:

Now i and many other need to use your osd in conjunction with Multiwii controller.
It have an serial comunication protocol (MSP) witch allow interogation and passing data between osd and controller.
Please release an remzibi OSD version with MSP Multiwii Serial Protocol.
Thank you.

Hello

Yes, I am starting to work with new MWC protocol at weekend , so new firmware to OSD will be ready soon .

regards
