The maple mini and the Blue Pill use basically the same processor. Well, the Blue Pill is supposed to have an STM32F103C8, but despite being marked like this, it actually has an F103CB version that has 128kb flash. The same as the Maple Mini. I know because in some projects I use much more flash mem...

Er9x is a wonderful firmware. Abd it is still being maintained for this radio as far as I know.

João

I would like to see it on the STM32F103 based Blue.Pill board.
It is great, fast, lots of memory, and it costs next to nothing.

My guess is.that you might have shorted something

João

Sorry, my phone tricked me and i thought I saw 2 different threads..
My bad.

Check for shorts on the output path of the 3.3V regulator, now that you lifted it's pins.

João

It would be nice if you shared what the problem was.. It could perhaps help others with the same problem

João

Check for shorts on the processor pins. I hope you didn't kill it with some short. :( And please keep the subject in only one topic, I think I have already answered the same question on another topic. Like this the information will be scattered and it will be difficult to provide some decent help :(...

It sounds like a short on the 3.3V bus..

João

It would help if you tell us which radio and firmware..

João

Offsetting the transmitter 45 degrees introduces 3 dB of loss between the vertical and horizontal antennas on the aircraft. This is as well as any pattern loss. Yes, but you have more chances that the side of the TX antenna is pointed at the aircraft. Also, normally the aircraft flies at an angle i...

According to my experience, if you fly gliders, normally overhead, both antennas horizontal on the plane and at 90 degrees to each other.. Radio antenna also horizontal. For normal (acro) flying, in my opinion, one antenna horizontal along the fuselage, and the other vertical. Radio antenna pointing...

Thank you..

João

Mike, is it only for the 9XT or does it also work with other radios? I am asking because the other apps work on all radios, I think?
But EEPROMs are different..

João

Now you're talking Chinese.
But I don't want to go off topic here, so I will start a new thread..

João

I.am sure you guys are.all enjoying my disgrace ha ha
I have no idea what model it is Bob..Oh, it looks like the free version of Tapatalk doesn't let me post pictures.anymore
Will try tye browser..

João

EDIT: Here it is

You just had a good laugh, right?
Yeah, it is about time. And my son will love it too.. But I can expect a few headaches.

João

The app would be the best option in this case in my opinion. That is a great idea Mike. Thank you

João

Oh, I see.. But if the radio is completely dead, I don't know if maintenance mode will work. As far as I know it is part of the firmware But Mike knows better than me of course..

João

I have just checked on my 9xtreme radio. You do have a "Restore" option in the Radio "Settings / EEPROM" menu. You can use it to restore the EEprom you have saved to the SD Card.

João

Bob, I have been given a 3D printer by a friend.. I guess you will have to set this complete beginner in the right track
Well, you don't have to obviously, but any help when problems start to arise would be greatly appreciated

João

OpenTX does not support the PRO anymore, as far as I know, and some people have also reported problems that I think were not fixed. Your best option for that radio is still ErskyTX. It is still being maintained and developed. try www.er9x.com for the latest releases of ErskyTX. Here you find ErskyTX...

.....but also Rc diy in general does not seem to spark a lot of interest lately. (just my impression, but I am often wrong). Unfortunately you are right.. Happy were the times when we were modding and flashing the 9x radio :( I really miss a project like that again. I did work on a few nice project...

I think you can but not sure. I know we can backup the complete eeprom to the SD Card.
I don't have the radio with me at the moment, but you can check in the Radio Settings/EEprom. You might have to unlock the menu by holding the left horizontal trim to the left at power ON.

João

It is not an SMD switch It is through hole.

João

Well, I think there would be interest for models running on 6s as it is much more accurate. Also multiple sensors would be good for models with more than 1 battery. At the moment I am building a model that will probably have a battery powering each of the 2 motors.. So, two batteries. I still didn't...

There is no .ino file. Mike provided a compiled file only. It could probably run on the NANO though as it uses the same chip. I think I tried using a NANO but wasn't successful with it. It was also long time ago :) I think someone had more luck than me. Please read this thread, I think the discussio...

Thanks.. what about two ADC chips? Could they read up to 8 cells? Are they i2c?

João

In other more common words, it means the switch is OFF.

João

Please note that the voltages of the 6th cell will perhaps not be very accurate because it will be calculated substracting total 5 cells voltage from total 6 cells voltage. A small error on total 5 cells voltage and on 6 cells voltage will have a much greater impact on the difference. Hi Michel, I ...

If you search these forums, I did modify one of my 9x radios to hall sensor. I built the sensors using its own potentiometers, some magnets, and hall sensors. Can't say it was an easy task, but they seem to work, even after a few years :) I am not near my PC at the moment, so I can't post any link. ...
