      Hi, glad to hear someone wants this! :) I'd forgotten about it/not worried about it since no-one asked. I'll see what I can do in the next couple weeks. I'm not sure if I want to turn it into a library or just release it as a stand-alone sketch. I'll think about it some more, and when able, post it for you. I have planned a post describing what a PPM signal looks like too, since I haven't found any really good explanations or pictures on the web in my brief looking around online. A good digital oscilloscope reveals all....

      PS. How did you come across this article? Since it is empty, it has not been visited very often.

      Hi, sry for the late reply. I searched for "rc receiver arduino" and found that site: http://www.camelsoftware.com/firetail/blog/radio/reading-pwm-signals-from-a-remote-control-receiver-with-arduino/
      There is a link to your site (especially regarding your micros() function) and then i found this article. It would be cool if you write a library for this use-case.

      Sry for my bad english and thank you for your time!

      Nils, your English is fine. No problems there. I just stumbled upon some PPM-reader and PPM-writer code that is already out there. I haven't tested it, as I'd like to write my own libraries for this anyway, but it does look worthwhile to check it out:
      1) An interrupt driven RC PPM frame reader for Digispark, Digispark pro and UNO
      2) An interrupt driven RC PPM frame generator for Digispark, Digispark pro and UNO
