Re: Retract servo programming

You need only half of the movement.
I guess you already tried something like

CHx 50% FULL (switch) AIL

Re: Taranis QX7 bluetooth

Thanks Mike, I have been quite busy lately, but I have a radio with skyboard open on my computer desk, so I think I could test on that one.. Did you find a through hole low Vgs P channel Mosfet? Or did I misunderstand your post as usual? ;) I do have a few logic level P channel Mosfets, but they are...

Re: er9x development

Because you don't have to remember to change the switch settings for different models. The radio will do it for you automatically when you change models..

Re: er9x development

Understood. :)
Just a note, Ersky9x, which is a more advanced version of Er9x (more features) also runs on Frsky radios. The menus layout is basically the same, so you wouldn't have to get use to something else.

Re: Taranis QX7 bluetooth

Mike, Through hole N channel Mosfets are more readily available than P channel. this would allow people to build the circuit on a bit of stripboard. Could something like in the picture be used? I tested the circuit in a circuit testing software and it seems to work. Although the BS170 datsheet state...

Re: er9x development

Ok, your choice.. :) The extra RAM of the m2561 is really welcome as it allows for features not possible on the m128. Er9x supports way more extra hardware than opentx, which only supports a parallel voice module as far as I know. Also, development for this board seems to have stopped. Er9x continue...

Re: Taranis QX7 bluetooth

A BJT is controlled by current, so won't turn on unless something actively pushes current through it. Well, as I said above, I have seen the opposite. The circuit wouldn't turn off if I didn't connect a resistor between base and ground. Looking at the circuit Mike posted (without the resistor), tha...

Re: Taranis QX7 bluetooth

Thanks Mike, I see you omitted the resistor going from the base of the BJT to ground on your first schematic. Won't that prevent the transistor to turn OFF? Or is it enough when you pull the processor pin low? Also is the pin floating at any occasion, for example, at power ON? That could activate th...

Re: er9x development

You could have upgraded to the m2561 instead. It has the double of the RAM as well.
I believe it also has a couple more pins that can be used for extra switches..

Re: Taranis QX7 bluetooth

That can be done with an ATtiny, or you have another type of circuit in mind?
If it is the same as you do for the power modules, than the circuit I use will work without modification??

In theory, but they all have different possible "spare" signals, if they have any at all, so would take time to allow selection and configuration.

Re: 4in1 module dead?

Did you remove or insert the module with the radio turned ON?

You will probably have to open the module and check why you don't have voltage where you should.

Re: Assistance with alarm setup

Try setting rate to "10" as you want it played every 10 seconds. do not use BOTH in this case
Also set "Play Source" to "No", as you do not have a voice module.

I'm not sure I understand your problem. If you want the radio to beep when the throttle is under 100%, then set a voice alarm as

Function - v<val
Value - +100%

Er9x is a lighter version of Ersky9x. er9x runs on less capable processors.
