Mike.

Thank you, sir.

The easiest way is to re-calibrate the sticks. When calibrating the throttle, move it to the bottom position gently (or even stop just before it hits the bottom). Then move it away from the bottom position when moving it left and right for the rudder. I have seen the situation where if you hold a s...

Greetings. On my particular 9x unit, the throttle needs to usually be pulled quite hard all the way downwards to avoid the throttle not idle warning (which I'd prefer not to disable). Where would be the best place to adjust er9x settings so that the throttle was considered idle when it was essential...

My understanding is that the main reason there is no capability for users to edit the names of the five (?) flight modes whose parameters can be independently edited in er9x (for display on main screens, etc.) is memory constraints, particularly on the m64. Right now FM 1 - 5 can be displayed, but ...

Done. All fixed and apparently working as advertised! I used Steven's recommendation for +5 rather than andrewju's since the former was more isolated and didn't risk lifting any attached component, but thank you both in particular for the specific suggestions and thanks to everyone for helping on th...

Yeah, that looks like an easy one. Thanks again!

Super. Thanks. I just don't want to tamper with success now that the board is working 100% for me as currently installed. I'll wait for your images before proceeding today. Thanks again.

By the way, after this kind of mod, would turning on the radio while the USB is connected actually cause any damage? Thanks.

I can't do it that way since it would require removing the SP Basic board to get at that VCC pad. I can't risk removing the board. Can't I tap 5v somewhere else? Thanks.

Well with the basic, you need the radio ON anyway, right? So, I guess it is a good idea, yes.. João That's it. With the SP Basic board powered up via USB the AIL switch is working properly in the diags. As soon as USB power is removed it stops working. So the SP Basic must be loading the switch whe...

Right, the SP Basic needs the radio on, and USB power simultaneously. I'll test this shortly. Thanks.

Then if you don't want to remove it, you will have to follow andrewju's advice. If that doesn't help you will have to live with a dead switch. You could have a short to ground somehow under the sp basic, or the board could be loading the pin where the switch is connected. You see, the sp basic shar...

Yes.. and if you remove the switch and still shows zero you will have to remove the sp basic anyway if you want to find the problem. João It's not an option. I won't tamper with the SP Basic installation. It's just too unwieldy and sensitive. I've learned my lesson on this. Can you explain more abo...

Removing the SP Basic board really is not an option. As I noted above, getting it working in the first place was a challenge in my particular unit. Would the switch show as 1 if it was open?

Do you, by chance, have a SmartieParts Basic installed? I recently had a 9x radio with exactly the same issue. It was related to the SmartieParts Basic board the owner had installed previously. A simple test would be to remove the SmartieParts board (or any other programmer) from the radio. This sh...

Does the throttle switch work? You said that the switch shows always "zero" in the diagswitch screen? Can you confirm this? If this is the csse you might have a short somewhere. Do you have a programmer permanently installed in the radio? Have you done the telemetry mod? If so, how? João ...

With the current build of ER9x (I have no info about this with earlier ER9x versions or the standard 9x firmware), the AIL switch appears nonfunctional. I discovered this when attempting to use it in a mix. The diag page shows it always at zero. I don't have an immediate need for this switch -- in f...

Great that all ended well. I hope I see you around on the forum ;) Don't forget, as you didn't protect the eeprom, best is to save it always before you flash the radio even if eepe also does it automatically ;) João Understood. I'll be around. For what it's worth, here's my little contribution to t...

kaos wrote:Now you just need to flash it again for the new r820 just released today.

Already did! When I was doing a round of tests today (the 9x is completely unconfigured) the notification for 820 came through so I went ahead and flashed, A-OK!

9x is back up and running er9x successfully. Details at: viewtopic.php?f=95&t=8339

Thanks all!

Status: er9x UP (was offered new r820 by eepe, flashed it and replaced 819 from last night's test) SP Basic board is working without any manual pressure required (but finding a way to keep it in its rather precarious position where it works, and not slip out from under that washer again is a priorit...

To enable beeps go to Radio Setup/ AudioHaptic, set "Beeper to other than "Quiet" Also make sure that "Sound Mode" is set to "beeper". You can also set it to "PiSpkr" If your radio is flashing the firmware without errors I believe it is safe to set the f...

Actually you will have to format the eeprom all the time if you didn't set the fuses to protect the eeprom. every time you flash the firmware, the eeprom is erased.. then you have to burn the eeprom to the radio again.. In eepe "Burn" menu. There is an option called "Set fuses to pro...

You have replaced the original stock firmware with er9x. This means the EEPROM data is still that for the stock firmware, since you didn't manage to actually run er9x before you got the burning problem. The "BAD EEPROM DATA" is therefore quite normal, er9x needs to "format" the ...

Ok, fix it.. but you should get beeps even with that track broken... try the eeprom read.. That will tell us if the cpu is working.. Remove the RF module for now.. João Major progress. It's not a dead parrot. Status: Reinstalled switch board and RF module backplate. Patched around the burned trace ...

Will do. Well, since there's no beeps, it's not looking good. Thanks.

Yeah, this is getting a bit strange. :o Ok, next step is to check the processor receives VCC (5V) and Ground where it is supposed to. See picture This is NOT an easy task, and it will require that you be very careful not to short the processor pins with your voltmeter probe. When possible try to me...

Because maybe the backlight is powered by the RF power circuit which has a burning track ;) That is a possibility.. I never used the backlight like that though. Always had some circuit to control it from the radio.. Anyway, you seem to have all the voltages. Lets check something else.. 2 things: - ...

Got it. Will do. Thanks.
