Register a callback in micropython to C ISR reception

[ghost]

Hi there,

I wrote a library in C and I have mapped it into my Micropython project. This library implements a Queue and I'm avoiding polling to get data from this queue from Micropython. How can I register a callback wrote in Micropython at the reception of an ISR or event into this C library? What I mean is how can I execute a callback into Micropython as soon as I receive some data into the Queue?

Thank you very much
