I2C and broadcasting
PostPosted: Thu Mar 01, 2007 7:48 pm     Reply with quote
Hi,
I would like to know if I could be broadcasting a i2c_write during a loop? To be clear, I am running 3 ic’s as slaves and one master. The problem that I am facing is that sometime one or all three ics will go in to a loop and I need to send the master the status (on the slave IC) which is in a loop. I am guessing that I can’t broadcast because of the structure of the I2C.

If I can’t broadcast, can I use an interrupt, the question regarding this is: if an interrupt signal is detected and goes to that function, and when that function is exited will it resume the position of the code it was before the interrupt.
Thank you

Yes, that's how an interrupt works.
