WHats the cost of the Atmega 32 ?

Edit: on Ebay its about 7$ with shipping included. not a bad choice really !

callelj: I think I got it.

Calculates distance and bearing, returns sin & cos directly. is very small, should fit.

Will test some more, and send you. Only good for small distances (few km)

I think the point is he wants to use the existing hardware. Why stop at using a better uC . It makes no sense to replace the existing uC, because once you have reached that point why even bother using the stock pcb. Desgin a new PCB based on the capabilites of your new uC. Now you are no longer improving an available piece of hardware but creating your own osd system. I would rather just buy a OSD system than go through all of that. I have a few highend OSD systems and I also just purchased the G-osd to play with.

I believe the idea is to take the cheapo HK hardware and make something useful out of it with better coding. Thats admirable and Im looking forward to seeing what he comes up with.

Hi callelj,

I just uploaded the hex to my E-OSD. it is ok, but i face some problems.
First one is the the image is static..
second one is that my camera is NTSC
third is that there are interference.. if I put the hand close to E-OSD then I start to see some values of battery one.. to see the arrow is moving 360 degree.. but have very distorsioned picture and some times.. black and white..

can you add the NTSC support to it.. then i will start to play with the rest..

and yes... I think that the onboard led should be switched on, otherwise is hard to understand if the osd is on or off..

schumixmd: Hmm, does not sound so good. I haven't tested the latest E-OSD hex I uploaded since i'm focusing on G-OSD right now.

NTSC is on the todo list but I have less time to work on this project right now. :-/

I have seen the interference bug before. I really don't know if it's a hardware error or a software error. But it might have to do with the fact that plastic cover has been removed. I really don't know. It would be interesting to see if a stock board without the cover have the same problem.

Yes, the onboard led should light up on E-OSD. Adding that to todo list.

I do have the GOSD too.. but I'm flying with it, so I don't want to reprogram it right now, that's why I started with EOSD, and i'm thinking of what I said before, to add GPS compatibility to EOSD by soldering 2 pins on RX and TX pins from the atmega.

I think interferences could be because I didn't disconnected EOSD from arduino (I use arduino as avrisp), only V+ and GND.

schumixmd: Ok, might be that.

I think I will try to move the characters from program space to the EEPROM instead. That might free up some program space. But it will require everyone to program the EEPROM as well.

I think I might have to add float but not use math.h but instead do my own functions using taylor series. But I don't know if it will fit... Hmm... Tricky...

callelj: routine working so far, just covering corners of the envelope, should send you today.

esreis: Sounds good, sent you an email...

I tried to move the characters to the eeprom but it was only 512 bytes so I could not fit it there. :-(
Might need to remove some characters but then I will need code to compensate for that...

Do anyone know how to see what takes up space in a program on AVR?
I remember that I could get a graph of it when programming PIC...

callelj: Tried and failed to send the routine - messages have size limitation.

traded off speed for size, has slow functions, but is small. I don't think it could be a problem at 1Hz.

haven't received your email

Sounds great, size optimization is better right now.
Sent the email like 5 min ago so might still get there. :-)

could deleting the second voltage reading help to make space?

You will need a avr programmer.
