I want to WRITE a Pulse Position Modulation (PPM) to an arduino from a raspberrypi. Is the board capable to do this and if so, from which port/pin?
A pulse position modulation is a signal that consists of a priod of silence (sync reset) and alternating pulses separated by periods of constant silence.
As per the suggestions down below in the comments:
- Channel max pulse width: 2000us - Channel min pulse width: 1000us - A constant number of 8 channels - Frame rate: One frame every 10 milliseconds
The information is read from a server via C sockets (in a client-server application)
I receive the message from the server and after being decoded we are left with:
This will be broken up into chunks and assigned to variables. A function uses these variables to create the signal and send it via GPIO.
Could you point me to what C library I could use to do this or point me to further reading on this subject?
Apparently @joan has a library on this. I read the specification on this site, but unfortunately I don't know python and I don't know where to start with C. I see the C examples on PPM are missing. I am happy to share my code with the owner of the site if someone could guide me on it afterwards.
