[Q] Any project like PiFM, GPIO only FM transmission on BeagleBone Black?

I'd like to create similar thing like PiFM in BeagleBone Black. Can anyone provide me reference on this?

Thanks in advance.

Its impossible .
bcm2835 have flex pwm and dma transfer for fm turning .
while am335x pwm is only for fixed clock div .

Oh, sad… thank you for kind and detailed explanation :slight_smile:

In fact, what I am interested is not tramsmission of audio, instead, other signals like morse code. If this could be done using PRU
then I would try to find how could I make “PRU cleverness” :slight_smile:
