Here is a good reference for the captioning: http://nootropicdesign.com/projectla...ed-captioning/

Thanks
I don't have any plans at all, I'm just doing it for fun
Lets see how it turns out, still some work and testing left.

It will take a while before the PCB arrives, but hopefully they will arrive within a few weeks.

Well....maybe you could include the MS561101 - Fab has updated the code for this amazing little guy. check it out in his library - FreeIMU library - 2012/11/06 found here http://www.varesano.net/projects/hardware/FreeIMU

Hi guys just threw one of these together yesterday and it is working great! Ive been trying to read through the entire forum but frankly it is way to long :P. So my question is has anyone implemented both the osd and antenna tracking such as http://code.google.com/p/opendiyantracker/.

It's a really nice sensor-board, but it's a bit pricy compared to other sensor-boards available. While I would love to use it for some more fancy autopilot etc. I wouldn't use it for this.

Nope, it haven't been implemented
Just remove all the menu-code and you should have plenty of space to implement it

Howto upload new firmware to SimpleOSD Open?


Hi!

I am trying to upload the newest firmware to the SimpleOSD Open Board (green LED).

I have a FTDI Basic from Sparkfun (https://www.sparkfun.com/products/9716) with the following wiring:

FTDI -> SimpleOSDOpen
5V -> +
RXI -> T
TX0 -> R
GND -> -

GPS is not connected right now.

I tried to do exactly as described here (http://www.flytron.com/osd-headtrack...uino-boot.html), but I get always the error message:

avrdude: stk500_getsync(): not in sync: resp=0x00

FTDI works correct (tried it with an arduino mini).

Does anyone know if my wiring is correct?

Thanks!

Familiar error to me :P Its a communication error somewhere down the line.

Try switching your TX and RX lines.It is a pretty common thing for a board to have TX and RX switched on purpose, but it is incredibly misleading and annoying.

Another thing is that you don't seem to mention anything about a reset wire or pressing the reset button, one or the other is a complete necessity.

ugh, on my simpleosd open I solered a reset line onto the atmega (what a pain!) and then the code downloaded. And then the thing still didn't work.

OK! I soldered the reset line as well. Then I tried to upload. Board resets nicely (green LED turns off) and I can see how the FTDI tries to communicate with the simpleosd (red TX led is blinking a few times), but I still have the same error message:

avrdude: stk500_getsync(): not in sync: resp=0x00

I tried to switch RX and TX, but no luck.

Are there any additional ideas?

Thanks!

Yes, Arduino Pro or Pro Mini 5V,16Mhz with Atmega328.

If you have selected the right COM-port, Arduino and have the FTDI -> SimpleOSD connected right - there's not much left you can have done wrong

It's a bit difficult to time it right. My FTDI-converter have a LED for receive and transmit. I normally wait until the TX-LED on the FTDI converter flashes and immediately turn SimpleOSD on.

Also might want to check and make sure there is a bootloader.

I think I have seen that error when for some reason I confuse my computer's usb ports - sometimes I simply restart my computer - plug in the usb - make sure the computer see's the usb - then the error goes away

I had a problem when trying to flash my X9 with er9X. Make sure there isn't a current limiting resistor in the programmer. When ever I tried to flash it would just reset and give the same error you posted above.

Hope that helps
