Hi dear friends, finally I started to read the docs. The chapter on interrupts is for me too difficult to understand so my Q: 1. how are actually interrupts handled? I've seen the source of Lubos Pekny's keyboard driver, but it is too complex to understand the concept 2. I am running the sieve demo and e.g. I'd like to unterrupt simply the interations by ctrl-C. How shall this be done? 3. Is there an access to ISR? Can I put something in it? 4. How the OS is using interrupts? Any periodic activity (ticks, heartbeat..) 5. How to write a simple interrupt routine? Any simple example? E.g. from rx? Thanks a lot, Pito |
