not an issue but a doubt #99

Open iamharshit opened 8 years ago

iamharshit commented 8 years ago

just wanted to know like we can use external interrupt ,can we use timer interrupt too in beagle?

alexanderhiam commented 8 years ago

Well, that depends what kind of accuracy and resolution you need. There's plenty of ways to do timed tasks in GNU/Linux, like cron, or event-driver frameworks (e.g. Twisted or Tornado for Python).

actually i was working on implementing a rpm-encoder on beagle using PyBBIO, but for that i needed external interrupt and timer interrupt , although i got to know how to use external interrupt in PyBBIO, but still stuck on how to use timer interrupt in PyBBIO. any direction from you?

Have you looked at using the eQEP modules? They can very precisely count steps from an encoder.
