Seems MAX7456 does not starts

[shadowroot2]

I just uploaded to OSD board (without connected RX5808 SPI pins, but connected gnd, vcc and video out, so have signal) and have black screen only. Seems like MAX chip can not start...
By uploading MW OSD firmware have all works.

Hi,

it should bring up OSD scree without a tranceiver. There is no hand shake between the RX and the CPU.

One thing: the overlay is muted after some seconds when no key is pressed.
That may be the problem.

A lot of people did already build there receiver... nobody reported that issue.

In case you have an connected ISP programmer, disconnect it, since the ISP pins are shared
with the SPI bus.

There are some reported probelms, with power supply issue.

I use the inbuild regulator with 8-12V dc (as in the wiki), do not power it via the USB dongle only.

Just tryed on other Minum OSD (not Whitespy)....result the same - black screen only

[markohoepken]

Hi,
I guess the SPI buss is for unknown reasons not working...

Are you an experiencend "builder"?

You can send me a private mail... may be a little easier:

marko@hoepken.eu

Yes, I uploaded hex, and result the same.
Can you do test? Only osd without anythink only uploaded code and
12v power and video-out.
May be somewhere dependecies if no input video signal or can not write SPI.

What do this code?

#if 0
while(1)
{
setChannelModule(1);
delay(200);
}
#endif

[markohoepken]

...
if you know C...

it just a debug fragment to test the setChannelModule() function

But since #if 0 .... #endif
ist always false... it will not go to the hex file.

I coding on PHP, and newbie to arduino C, trying to understand why not starts up. This code not should be #ifdef debug
I see many defines unusesd in code

Hi,

just to be sure, that the latest build is working:
I programmed it into my testsystem and it is working. But a tuner is connected.

So the problem ist not related to the software. As said: Works for may other builders.

Two thinks:

1. Is the board correct set in your Arduino?
   The Board must set to: Adruino Nano with 328
2. The default software starts with PAL video system. In case your Monitor / Camera is set to NTSC
   it will not show OSD.

Good luck,

Marko

Hi shadowroot2,

I added a simple OSD test to the repository (osd_test).
Please update and try it on your hardware.

I am readly interersted, what you problem is.

It may be releated to the different board.

Marko

PS: what is your name?

[shadowroot2]

Test work good! See counter.
Can you add splash screen 2-3 seconds to main code?

[markohoepken]

Hi,

good, that its working.

There is no need for splash screeen, since you see the last settings anyway for 10 seconds.
Than it will disapear... like a splash screen.

When you press a button, the screen cums up again.

I can not tell, what went wrong at your site.

I am afraid you must search by yourself.

markohoepken, I think i found problem, I just set in setup state = 1; I see osd now.
Seems in EEPROM old values from other software. And I totaly no have signal from RX5800.

[markohoepken]

Hi,

that are good news.
I will think about a mechanism to ensure clean startup values.

What means: And I totaly no have signal from RX5800?

Marko

OSD displays on black screen, no have video from RX module.

[markohoepken]

Hi,

sorry to say, but its not easy to build as stated in the "Wiki Build Warning".

Steps to debug:

1. Connect a camera directly to the OSD
2. Check the SPI RX patch and the additional wires on the CPU

This looks like wiring / soldering...
