Thx, whish I had more spare time to work on new features ;)

To run an executable on startup the simpliest way is to add proper command to /etc/local.rc file, if you want to be more sophisticated register fm_transmitter as an systemd service,...

Have you tried: ``` sudo install ./fm_transmitter /usr/local/sbin ``` after compiling this app?

ie. put this in console: ``` sudo su [type here your password] while true; do ./fm_transmitter -f 144.0 my_file && sleep 1; done ``` Notice there is not "-r" as...

The problem is in clock resolution, at 146 MHz RPi is not able to modulate sound using whole bandwith linearly. There are 2 or 3 frequencies available in 20 kHz...

Please specify your hardware and used frequency.

As this project still lacks resampler (will be working on it in next few days) sound quality, esspecially on lower frequencies might be poor. Try changing bandwith (aka volume). You...

DMA controller was changed in RPI2, so old solutions based on pifm project won't work. I will add stereo support in fm_transmitter soon.

Does it work first time after reset of CPU? Maybe its matter of resetting DMA, PWM or GPIO settings. I don't have RPi to test it right now. Must say,...

It's because my code switches pin 4 (antena output) back to GPIO operating mode, so no more radio waves are emited. Nothing really important. In the PiFmRds, part of code...
