I have ordered a turbo-lite and am reading the documents at the moment. I don't see a way to wait on hardware events (for example, interrupts caused by change of level on pin, overflow of hardware counter, etc), by OS commands. Is this true or did I miss something?

If it is true, then I would try to use the capabilities of the AVR directly. Is this possible, and how would I implement it - just wait for a global flag set by the interrupt inside turbo_handler maybe?

Thank you for any clues

You cannot wait(=sleep) for such events because mcu has to respond to phone in limited time. But you can use IRQ though in limited way. Don't forget that there are no clocks 99% of time - they are stopped by phone to save power.

You can use IRQ as any action, e.g. there is ACTION_SIG_2WIRE_SERIAL, reg_action() and hadle it in turbo_handler().

You have to set up the hwd to generate appropriate IRQ by yourself, kernel handles just the IRQ and sends it to application that has it registered.

Ah, I did not see these ACTIONs related to IRQ before, because I was looking in the Turbo documentation, and these seem to be only listed in the Programmer doc.

Is it correct to assume that these defines are also available on Turbo Lite environment?

I guess this is what I was looking for anyway - thanks again.
