As pi2 have processing power of 900MHz it can generate upto 250Mhz radio frequency. I have run fm_transmitter on pi2 it was working but only with one song(star_wars.wav) and code was in c++.
Does anybody know how to create radio wave with pi2 in python?(simple code)
How fast i can toggle the gpio pin to generate below digital signal?
According to: http://www.networkworld.com/article/2999977/opensource-subnet/how-to-turn-a-raspberry-pi-into-an-fm-radio-transmitter.html
these radio transmitter projects work on the Pi 2:
Sadly neither of them are in python.
However you could run them from python using the subprocess module. https://docs.python.org/2/library/subprocess.html
Make Magazine created a raspberry pi pirate radio coded in python using a gpio pin and some wire. I haven't tried this project before myself, but since it is from Make Magazine, we can assume in functions properly. This project can be found on this GitHub repo.
For python the pigpio library is probably the best for what you want to accomplish. There is many python examples on the pigpio website. check it out
