But we might get an agreement, if we say "Form follows function" :lol: I knew I did something wrong with my PPM Tester :D Thought I build a case for the display and get the rest easy in ... wrong way :D That's why I crunched the rest in the box, but now nobody can see it ... Form follows ...

I wonder if it would be possible to implement one of these in the radio itself :) Big screen, no extra hardware, etc.. Maybe it could also receive PWM.. A dedicated menu in radio setup, etc :) Mike? :P João I think with the Taranis it could be possible (for CPPM ...), because you can feed the train...

very good.. I might give it a try even if I have built another one.. Mine cycles the servos too. can this one do that?. I don't think mine reads ppm though. only pwm. João This one measures CPPM (from rx or tx) and shows the actual position of every channel in the stream (1000-2000µS), also PWM out...

Thank you for your code and help !
Here are some pics of my version ...
maybe someone find it usefull for own creation

Glad to hear you have it working. The values you enter are used whenever you have PERSONAL_KEYPAD defined, and should work fine even if the keypad really is one of the standard keypad/display shields. Andrew With "standard" Shield Keypad defined it did not work ... strange :D But I build ...

Got it !!!

If I change line 46 and 53 of the code and use a "Personal Keypad", but use the same values for the keys, I can now switch to desired test modes and servo out works now ...
Don't know why, but it works ...

Tested with Arduino Uno & Shield, pot on A2, servo out on pin2 ...
Same problem ...

Sounds like the keys to select up/down are not working - have you seen them do anything? Which keyboard approach are you using? Do you have a pre-assembled arduino display/keyboard shield, or did you make your own? If you set the test input back to A0 and press each of the buttons you should see th...

sorry for asking, but ... I tried this little thingy here with the latest code from git, but have no clue why servo out is not working. Double tapping right button brings me to "PPM OUT CENTER", but no reaction to up & down button, no change of servo position ... Can't change "CEN...

Thank you, I'll try to learn
I post here, if I tested it and if questions are left open ...
But at first, I do read my pizza

As I told, for me the code works, but without the reading if a jumper on TX is set, so only drawback is to switch from ch1-8 to ch9-16 without reflashing ...
But as you said, I'll wait to get the next code to test ...
Thank you for your work and time

Thanks for feed back. Your changes were right. sorry for my mistake. To answer your question, I can say the following. It is nearly impossible to write a code that is 100% correct from the first time. Therefore it is important to have some way to debug the code. ... No problem for me, I understand ...

Hi ... As I wrote you in pm I tried your code and found it usefull :D BUT: I found one little problem with channel 14 (on A5) of the PWM outputs because this pin was not set to output. Through try & error I found and correct it, so ALL 16 PWM channels are working now :D thank you for that code. ...

Pin 2 of the processor. As it comes through as T2, T2 has a value from 0 to 255 for an input voltage of 0 to 3.3V. You may wish to choose a divisor that makes the resulting value meaningful. That I've read before but thought this was'nt there with the new code ... I'll test that if I get a clou of ...

I use this circuit: http://openrcforums.com/forum/viewtopic.php?f=96&t=4373&start=120#p63590 . That has now been incorporated into the production units. Double check your fuse settings in the 13A. Make sure the clock /8 is not set. Mike. Ok I use that but with 15k resistor right ? Do I need...

No problem. We only have, effectively, an 8-bit A2D. This means on normal resolution (18.3V) we have a resolution of 0.07V. On high resolution we have 0.052V. I then set the Taranis range to 18.3V and set the alarms to a little higher value With this latest firmware, you can have a second analog in...

Tested now an Tiny13A with your code and the code Alan provides for updates ... My Tiny13A seems to be defective ... The Tiny13V works perfectly now ... One question do I have now: If I want to be shure for all setups that might arrive here (setup with external BEC, / with BEC fron ESC ...), do I ne...

Is it sooo simple ? Now I added an extra 2.2µF / 50V capacitor (need to resurect some better value ...), and all problems seems to be fixed ... wtf (I learned that back in the 80ties ...) Now I got on the supply for the Tiny13 one 100n capacitor AND one 2.2µF / 50V capacitor in parallel ... no jumpi...

Got added the 4k7 resistor ...

Range set to 13.3V
readings with low res mode - 8.50V - 8.60V - quickly jumping, real voltage: 11.60V
readings with high res mode - 11.62V - 11.97V - same as above

Range set to 18.3V
readings (low res) are - 11.63V - 11.98V - same jumping - real voltage: 11.60V

On Taranis: opentx-taranis-en-r2940.bin On Taranis internal XJT: XJT_131105.frk On X8R: X8R_131105.frk So all actual I think ... On more confusing, I added an 100n cap to Tiny13 pin4 - pin8, I thought I would not need it for testing so I left it ... and now the readings on telemetry screen makes onl...

Ok, I tried with r9 of your code (actual) from google, but also with no success ... I programmed it with avrdude: avrdude -p t13 -c usbtiny -U flash:w:Sport.hex -U hfuse:w:0xFD:m -U lfuse:w:0x1A:m Am I right with the fuses ? My actual Tiny13 has an "V" ... Tried also another Tiny13 with &q...

Thanks for quick reply :D I only got an 3S to test so I set the voltage range in my Taranis to 13.3V with no chance to set the offset, because of the fast jumping. If I set the jumper, I get the same readings as the settings for range, no real values ... strange ... With range settings to 18.3V and ...

Hello Is it possible to get the actual schematics to build this Sensor? I build Mike's first version on breadboard and tested it, but with no A2 reading on my Taranis. Then I've read that I need to update my X8R and my Taranis to use the X8R-2analog Sensor, but without FrSky USB (FUC-3) at hand I bu...

Hello, thanks Akkuschrauber for your answer, yes I just wanted to make a simple shield that anyone with a arduino uno could flash and use with a trainer port tx but.... first thing I think I burnt my a7105 because I flash arduino with shield on it (and it support only 3.3v max ) ...

... I personnaly own a V911 and recently bought a v959 after reading all this topic i decided to try to get all fnctions of my v959 with the t9x radio. so i unsoldered the a7105 tx module from my v911 tx, flashed one arduino uno with rc-ppm2spi.hex using avrdude by usb (keeping bootloader in) Is it...

Hi NeoMatrixJR, at first, to flip the v949 with stock tx AND 9x, theres NO one button solution ready useable, you need to use the flip button AND full speed stick movement in ELE or AIL direction, all this at expert mode with stock tx ... For an selfmade all-in-one tx module: How about your solderin...
