Have you tried with Pi3 ?

[Blenderpics]

well, without modification, it will not run

#if (RASPI)==1
(...)
#elif (RASPI)==2
(...)
#else
#error Unknown Raspberry Pi version (variable RASPI)
#endif

and even if you would copy the raspberry pi 2 code part, there is very little chance that all those memory adresses are unchanged in pi 3

i am currently not owning a pi 3, so i can't say for sure, but i guess it's not working

Yes, I know for the if/elif first part :-)
The "strange" part: there is no datasheet for BCM2837 yet (the CPU chip
on Pi3) while this document exists for Pi1/Pi2 (in this datasheet, I'll
find these memory addresses).

[ChristopheJacquet]

No, I don't own a Pi 3 yet. With some luck there's no change compared to the Pi 2 and we'll just have to update the Makefile.

Could anyone owning a Pi 3 try this?

I have a Pi3, and there's good and bad news.

The good news is that core functionality works - I've a usable (slightly noisy) mono audio signal on the correct frequency.

The bad news is that the stereo MPX signal and RDS were initially missing. (I assumed this was a calibration error).

Then I noticed that my receiver was muting on a lot of adjacent frequencies, so I physically isolated the Pi3 from the receiver, and extended the antenna connected to GPIO 4. Doing that improved the signal-to-noise ratio sufficiently for the stereo MPX and RDS to appear.

Even without pi_fm_rds running, the electrical noise from the Pi3 was getting into the FM receiver, so I think the problem might be that the Pi3 is generally noisier than the Pi1 I was previously using.

Hello, i'm testing this project with the Pi3, but i have 2 problems:

1. I need to put -ppm 125396 for getting back the stereo and RDS, if i don't set this calibration error, the audio sounds only in mono and in a pitch down tone
2. I have several errors in the system while the tx runs (ex. the system audio breaks from the first tx, and i can't restore it without a reboot, and, if i move a window while the tx runs, the system has freeze).

i dont have these problems with the "markondej/fm_transmitter" project (but the audio quality is worst)

Thanks, and sorry for my english.

@asp95 how did you get the figure 125396? I have a Pi Zero and this also worked for me. Without -ppm, or a low -ppm number, everything I tried to play was slightly slow.

[asp95]

@RegexPhilbin With the calibration method described in de readme, using Audacity with a record from the radio app of my Motorola phone.

[RegexPhilbin]

Thanks @asp95 , I was just hoping there was a quicker and easier way. It's interesting your value worked so well for me though. I wonder why that would be, on a Pi Zero, which as far as I know should be pretty identical to a Pi 1, and with such a high number.

Additional info: I'm running on the latest Retropie. I killed all the emulation procs, and either way have plenty of headroom when PiFmRds is running.

[ChristopheJacquet]

Just tested with a Pi 3. Works out of the box, just like on a Pi 2. Closing the issue, please reopen with details if needed.

[Niall7459]

@asp95 Were you able to fix the system freezing? I have the same problem since im moving my station to my pi 3 thanks!

[Niall7459]

@nickpiggott Is it worth upgrading my station to my new Pi 3 then or keeping it on my Pi 2?
I want the best quality and range..

[nickpiggott]

@Niall7459 I've not done any measurement, but I think the Pi3 is doing a better job than the Pi2.

[Niall7459]

@nickpiggott Hey could you help me on the Pi3 when I run PiFmRds its fine but then I go to move the window (or any other window) and the whole system freezes (I use VNC) but I can still connect to the webserver on the same pi, and then a minute or so after i cannot....

Please help I used to love PiFmRds

What version of Raspberry Pi are you using (Ive tested on Jessie and Stretch Pi3 but no luck with either)

Thanks

[Niall7459]

I updated to stretch and it has fixed nothing, shall I update the firmware?

[Niall7459]

Literally @nickpiggott Everything works, I can open folders, but as soon as I go to drag a window thats it! The system freezes and needs to be unplugged!

[Niall7459]

@nickpiggott Also the green light on the Pi remains constantly lit after it freezes.

[nickpiggott]

Sorry @Niall7459 - I run my Pi3 in headless mode without a GUI or monitor connected, so I can't help there. Sounds like you might just be trying to get it to do too much at once.

[Niall7459]

It is only running the radio station at like 5% cpu, then when I move the window it all breaks down.
Just did a firmware update and it still the same...

[Niall7459]

@nickpiggott Its definatley not being overloaded..

[Niall7459]

@asp95 Did you ever fix the freezing on your pi?

[asp95]

@Niall7459 no, i didn't use the software again

[Niall7459]

Alrgiht looks like il have to use my Pi3 to host the webserver and my Pi2 for radio.

[Niall7459]

@nickpiggott I am now running PiFmRds headless and when I got to sudo reboot i can still recieve the radio and the Pi never properly restarts!
