Er9x128

[Kilrah]

Yes!

Thanks Kilrah, would You be so kind to place other foto where can to see where You hook up external power?
I desolder out all wires, but it still don't work...

[Kilrah]

It's actually powered by the programmer on that photo.

Well, till now nothing to be good... I've desolder out all wires, clean all with alcohol, try to power board from USBASP, try to hook up other one display - nothing to do, it still be blank. So, before desolder out M128 I have two questions:
- can somebody, who had a success with a M128 transplantation, post here own fuses?
- does it possible, that I've fry in some mode LCD outputs (chip still be seen by PC)?
thks

Can you make a servo move by connecting it to a rerceiver bound to the tx?
does the radio beep if you mess with it?
If yes, then there could maybe be a problem with the LCD.
If not, than I think that the problem is somewhere else..

So, after spend one week of my f...d life, I find the answer... FUSES, guys, f...d fuses... I read fuses of my other Tx9 with M64 and copy it to M128. And a miracle happened!!! I was at one step to consider me an idiot... Thanks to all participants, the curtain falls...
P.S. For save the time and brain health of followers here are screenshots of AVRStudio.

OOOOOH, I've singed a victory too soon... Hooking up a voice board, I shortened motherboard. Was a nice spark and tantallum cap was explose me in face. Cap and M128 was replaced to new ones, but on display now can see something, like this:

Have somebody a weak idea, what's happened?

Hmmm, check the fuses?? Also after the short is the regulator still ok? and supplying 5V?
Answering my question, it might be or the atmega wouldn't work? but better measure

and check all voltage regulators
5Volt and 3.3 Volt on main board
5 Volt on the board with the beeper
5 Volt in the module

2 Joào: M128 is new, programmed externally, all is OK, veryfied already being soldered to MB.
2 Reinhard: can You post here a foto with an explanation, please?
thks, guys

[jhsa]

It doesn't hurt to check again.. It could be that is not working at 16Mhz anymore for some reason.. That would slow the screen down?
also where did you short the board?
A picture from the affected part could probably help?
I've learnt that the famous phrases "I've already checked it" or "it was working before" don't apply most of the times
We have to check and recheck, and recheck...

It should show you most of what you are looking for.

Possibly lost somewhere in othjer things in this thread, but I did update the first post with a test version of er9x-128 that includes flight phases and stick scrolling. No downloads yet. I was hoping someone would test the flight phases before I put it in a general release, I don't have a functional 9x with a 128 main board to do full testing.
I've just added a provisional r789, any testers out there?
