Found it in MODEL SETUP, GENERAL. Very nice, thank you

I tried that many times, together with many other options. That evening when it did work, the last thing I did “Now set back all the options you dont need”. With your answer and a bit of thinking (setting a cpu pin to input might happen during boot up) I managed now to do the miracle: Activating tha...

äh - yes, I measured the right one, just gave him the wrong Name ...

I have 5.8 mega ohm between pin 47 and Ground. Checked again there is no short to neighbouring pins either. Damn. If I can't find it I think I'll got for pin 39. R50 to be removed was correct?

The processor should have an internal pullup resistor on pin 43 (PG2) That means I should be able to measure ~5V there, when not connected to ground via switch? Have you set PG2 as an input in the hardware menu? yes Check your soldering. You might have shorted pin43 to ground somehow.. triple check...

Last night both switches worked, today the switch connected to pin 43 does not work (as expexted): Up position: original signal wire switched to ground, gives me arrow up in the DiagMenu: OK Down position: pin 43 switched to ground, gives me arrow down in the DiagMenu: OK Mid position: None of above...

Mike, yes , please

João, the RUD switch is not in the Hardware menu, so I can not set it:

OK, ELE switch is on Pin 35 and works like a charm (read about U6 only afterwards). The RUD switch is on Pin 43, but I can't set it in the hardware menu? The AIL switch is there, and so are PB1 and PB2, but no RUD switch. Noooooooo ... There is also PG2 Input and PG7 Input. I activated PG2 Input but...

As my experience with soldering on or near the cpu is ... hm, lets say, not so good, I would like to double check with you what I am doing. Here is an Image of my cpu: cpu2.png Pin39 = PC4 is connected to what looks like R50. Remove R50 and take empty pad connected to the cpu for one switch Pin 35 i...

Thanks guys for the quick reponse. Yeah, your radio has the backlight control already built in, right?. Right. You don't have haptic installed, right? Right again. How many switches you need to convert? Two What processor does it have? Atmega128? And right again (Do you have a camera installed in my...

I am lost. Have flashed er9x and can find the settings in the hardware menu. Have ground connected to the middle pins of the two 3pos switches and the original signal cable on bottom pins. But where to connect the 'new' upper pins to? I searched and searched (both the forum and my radio ;-)) but can...

Yeah, I expected that answer. Thx anyway João. I'll try my best and programm the FunJet first. See where this brings me to.

Dear all, while waiting for a new Taranis board I reactivated my old 9XR. I have gotten so used to the two 3-pos switches on the left hand side, I use them in nearly all my models (on the left I have throttle, so that hand is more or less free to move switches whereas I never, never take my right ha...

Today is disaster day (and "Father's day" here). While aligning & soldering the CPU I managed somehow to scratch the CPU over the complete board resulting in bend pins on one complete side. I got them all back but one which broke off. OK, smd soldering was never my thing anyway. Then p...

Bob, I have been admiring your soldering skills already. After cleaning yours looks so perfect. Did you apply solder to the tracks before putting the CPU on or is it better to start with as much of the old solder gone as possible?

with CPU____without CPU
P01: 4.8V____6.75V
P02: 4.3V____4.72V
P03: 3.6V____2.12V
P04: 0.15V___1.88V
P05: 0.35V___0.51V
P06: 0V______0.11V
P07: 0.1V____0.66V
P08: 1.1V____1.04V
P09: 0V______0V
P10: 0.6V____3.26V

R76 has 0.6V on one end and the 3.26V from P10 on the other. I presume I'm good to go.

CPU arrived: IMG_4267.JPG First cut the legs of old CPU and then desoldered them. I killed a few conductor tracks, see what I can do about that: IMG_4268.JPG Furthermore it looks like I lost C81. Anybody got the value for that? Continuing to remove legs and clean up, Rolf PS Mike: Can I try measurin...

Hello all, still struggeling with my board. As there are no more tips I will change CPU in case that is pulling the voltage regulator down but somehow I dont put too much hope into that. So I am forcing myself to get friendly with the idea of getting a new board. They are available with and without ...

I am not Andrew, but I bought mine here:

Not sure though if its a copy, for that price.

Gimbals and Switches are unplugged - no change. All the time while testing I was scanning for smoke, bad smells and warmth/heat - nothing. Cool as a beer should be. Connecting the battery again as >something< seems to suck it empty and measured amps: Switch Off: 0mA Switch On: 70mA No heat. Maybe I ...

I got annoyed with myself for not finding R76 so I took the main board out again and detached all cables. Still nothing. Then I bend up the Elko (looks like it was added afterwards, different solder) and voila: Hide and Seek is finished, boys. Reads 0.48V on one end, 0.12V on the other (measured aga...

Ah, great, both Light and Help have appeared, thx Mike. D6 voltages are 4.8 and 4.4 R76 is playing Hide and Seek together with his buddy, the 3.3V regulator. I cannot find them :? . The closest I get is R74 and R78 near the cable connecting main board and switch board. I am searching on the main boa...

When connected via USB, the junction of R57 and D2 works "as expected" (0.15v when the power switch is ON, and about 3.3v when OFF). Though, there's nothing on the screen and the PC doesn't detect any new devices. Hello I have swapped the body and gimbals of my x9r plus, but after putting...

Hi, I have a problem similar to this: http://openrcforums.com/forum/viewtopic.php?f=45&t=3450 In my case only the throttle switch is affected since I flashed to openTX. When I turn the TX on the switch is displayed as off which it is. When I turn it on the display shows this correct. So far, so ...

Test

Hi all, I have nearly the same problem as the thread starter. All switches working fine until I flashed to openTX. In my case it is only the Throttle Switch causing a problem. When I turn the TX on, the switch shows as "Off" in the display. When I turn it on this is displayed as well. But ...
