Look at output.cpp and start commenting out entire ifs in the detectline-method. For example, if you comment out this line (and the next 240 lines):

else if (line > toplinenumbers  && line < (toplinenumbers + 9)) {

...you will remove the speed and altitude numbers. Just continue doing the same thing for the other lines you don't want, but compile and test the code after each change.

I have done quite a lot of changes in the output code, but the code is still not looking good. Some major refactoring has to be done, but I don't know if the timing allows it.

thanks helped me !

Now i am done stripping made it from 27.296 Bytes to 2.828 Bytes
Plenty of room to add my own stuff now

Wondering what you're planning to add.

XDreamer what kind of changes did you make? Anything useful for the rest of us?

.

Yup, unfortunatly the entire code is quite a mess and pretty hard-coded. I never expectged that anyone but me should look at the code - sorry guys

Please note that the timer uses GPS-time, so you have to change it to a timer instead.

You are my hero anyway.

I'm planning to simplify the code, as I have made to many copy-pastes and have lost track of what is what. I started with the source from El_Nono in this post: http://www.rcgroups.com/forums/showp...postcount=1758
And his spanish comments / variable names did not make it any simpler. But Google Translate helped me.

I will post a zip with my OSD code soon, I will just clean it up a little bit.

In the future I'm thinking of something like this:

if (line >= line1Start && line < line1Start + line1Height) {
    printTimer(line);
    delay(20);
    printHomeArrow(line);
    delay(20);
    printBattery1Voltage(line);
}
else if (line >= line2Start && line < line2Start + line2Height) {
    printGpsCoordinates(line);
    delay(20);
    printBattery1Current(line);
    delay(20);
    ....
}

And text could be written like this:

printText("HELLO");

Of course, this could be impossible with the timing restrictions and the slow Arduino.

That would definitely make it a lot easier to customize. I just wrote the software for my own preference

I have moved on to other projects, but I'm still around if you need help with anything specific. I have a few things in mind regarding OSD, but it will be coded for MAX7456 instead.

i want to hook up 2 channels from my rc receiver to the osd to control stuff with my radio but so far i am very unsuccessful

Connected one to D2 and used interrupts to determine pwm pulsewidth result is that the osd and the whole image starts to flicker. however i can control the flicker with my radio

Hi Nabazul,
That looks good !
I am interested in seeing your stripped down code for this screen shot
Thanks for posting
Rick

So Dennis, do you have a schematic for the MAX7456 project or are you starting with something like this

Rick

Atm I have just soldered a MAX7456 on a breakout-board for initial testing (and the necessary components).
(3 SMD-caps on top left, crystal under the PCB, a few resistors etc)



The first test-versions of the PCB have been designed and shipped from production.
(PCB design have been updated a bit since this picture, but don't have it on this PC)


Another idea.. But not the one I have been choosing at the moment.



Latest version is with 0603 components, voltage-regulator, more capacitance and later I need to break-out some more pins for I2C etc.

These are the changes from stock 0.18:

• Smaller font
• Monitoring two battery voltages
• Moved the timer to a row in the top
• Added number of satellites (not thoroughly tested)
• Made it configurable to show current sensor numbers
• Battery bars and compass (configurable)

Most of this was done by El_Nono, I just added a couple of things and moved stuff around! And I don't think my version will work for everyone without tweaking it.

I think the smaller font will only make this useful when using FatShark Dominators or an LCD.display.

Dennis, you really should make this board for sale or license it for other to sale.

It's a work in progress - and I have just started. I don't really have any plans with the project, but I'm always open for ideas.

At the moment I need to design some graphic/characters - don't really have the patience for that

Very cool Dennis !!!

Can you post a schematic for us to work with ?

- I'm sure there is someone out there who could help with the graphic/characters
