Maybe there was some/a lot of misunderstanding. I will now continue to work on my project. CU

PS: I think the Mod can delete the thread, or the OT-Stuff. I'll maybe come back if I have enough to show.

Hey guys, I never wanted to be disrespectful. Of cause it is a great work which was done. But "jhsa" asked me some things and I just say what I've seen. Whats wrong about this? And I also said: ... Of cause in this case it isn't that critical because the fault on the result is very small i...

Out of curiousity, where you have: value = (value << 1); is there any reason you didn't write: value <<= 1 ; I personally find it more readable, and depending on the compiler often generates shorter code.. This is just because I copied the code from an app-note :D I don't know any compiler which pr...

While the files are .cpp, most of the code is actually just C, there is no code overhead doing this. Well, declaring variables within a for-loop isn't C. This is done in most cases. I wouldn't say it's bad. I would have thought that if you are doing your own software, and with the number of wires y...

Thanks jhsa. You are right, I do it for myself. But I wouldn't keep back my idea. We will see how good my idea works soon. I think not to use PPM is straight forward, like PCM. The nRF24L01 does all the CRC, retransmit etc. automatically which is very nice for security. The frequency hopping will be...

I do the firmware from scatch because the programming style of the er9x, radioclone etc. is awful sometimes. In what way don't you like the programming style? There are things I don't like, but the code is: a) inherited but functions correctly. b) Sometimes coded to save program space as it is tigh...

Here is the connection between the Atmega and nRF24L01 module.

PS: It it really obstructive that every post has to be approved by a Mod, because you can't edit the post immediately, if you forgot an image or so.

Yes I did a custom firmware. Well I would say I just started to develop. Nothing presentable for now. But the communication works. Of cause you need the nRF24L01 for the receiver (Quadrocoper, Heli...) as well. I do the firmware from scatch because the programming style of the er9x, radioclone etc. ...

Normally I attached some pictures on the first post, mybe they were to big. I updated the first post again.
I will do some schematics today I think. The schematic isn't really complicated

Hi guys, I modified my FS-TH9x Transmitter a little bit. Because I don't want to use the antiquated PPM/PCM signal I bought me two nRF24L01+ PA + LNA transceivers for $18 each. To adapt the nRF24L01+ PA + LNA to the FS-TH9x I used the "free" Ports for Software-SPI (PB7, PG2, PC0,PC6,PC7) a...
