Flysky PPM
What a show stopper, just ordered two of the inexpensive Flysky 6 channels RX and founded out, they no longer output PPM on the Battery Pin. WTH! Anyone have a work-around for these RX's or will I have to purchase some other RX? If so, is there one that will work with the Turnigy 9X transmitter without modifications?
Thank you.
Thank you.

I use Frsky JR modules in my Turnigy 9X.
Perfect match...

Re: Flysky PPM
But purchasing the Frsky JR module cost money, money that I am not willing to spend right now. Do you know of a work around for the Flysky?

I demolished mine but couldn't find PPM inside...

Re: Flysky PPM
The sad fact here is, they used to have PPM on the Battery Pin. All of the ones that I purchased up to now, had this. I wrote Flysky an email today but have not received a reply.
Re: Flysky PPM
I read somewhere they made a change some time ago.
To bad It's really cheep recievers..
Would be nice to ba able to reflash them....

Re: Flysky PPM
and it works. Sad, just sad!
Re: Flysky PPM
Copterrichie, did you get and reply from Flysky?
This is sad, those are great little inexpensive Rx-s. Is it a hardware change or firmware?

Re: Flysky PPM
Sorry but NO, I did not hear a word. Apparently others have made this same request so I assume now, they are just ignoring any additional request. I have resolved to building the PPM converter mentioned above, I am awaiting delivery of some 4.7K resistors.
And Yes, it is a shame because the RX worked great with the Failsafe feature of the FC.

i'm using this http://lea.hamradio.si/~s56wix/pwm2ppm/ (i've always some avrstuff/atmelstuff/ardustuff sleeping somewhere)
Works good, "physicaly smart" (plug easily in RX) and correct behaviour with sequencial and parallel pwm output

Oh, I like this. with some modifications, failsafe and a host of other features are possible. Thank you.

Re: Flysky PPM
I have bad news, those are the ones I most recently purchased. They no longer output PPM unless I am doing something wrong.
Re: Flysky PPM
Is there ANY receiver with PPM-sum output now???
I have a fs-tm002 TX module and want a receiver with ppm-sum to match.
If anybody has any suggestions please let me know here!

Re: Flysky PPM
It was not so bad, not it is time for lots of ground testing to make sure everything is working as it should be. Thank you PatrikE and everyone commenting on this post.

Re: Flysky PPM
FYI: I had the change the following in the DEF.ino file to get this PPM convert to work. Had to change the detection from RISING to FALLING otherwise, channel one went undetected.
I am happy, need to do more testing.
Code: Select all
//#define PPM_PIN_INTERRUPT attachInterrupt(0, rxInt, RISING); //PIN 0
#define PPM_PIN_INTERRUPT attachInterrupt(0, rxInt, FALLING); //PIN 0
I am happy, need to do more testing.
Re: Flysky PPM
Richie how is that rssi mod working for you?
Another thing how could we detect failsafe on this receiver so that multiwii could initiate some function like rth, when it detects failsafe.

Re: Flysky PPM
I have no idea on the RSSI, I gave that quest up as for the Failsafe, it appears to work as is but more testing is required. When I shut off the transmitter, all of the values in the GUI goes to the Failsafe levels.
Re: Flysky PPM
Which channel of all the channels do you use for detecting it? So you have it connected to an analog input on the arduino...Can you point me to the relevant parts of code in multiwii?
