I2C Interrupt possible?

[andy_ee]

Can I have a slave I2C R3 generate an interrupt on the end of an I2C transmission?

Events don't work for me here as I need to break a loop on receipt of the next I2C transmission.

I had this working fine with SPI but I need to use I2C.

Sounds like the loop you mentioned is "blocking code". Re-write so it is not blocking and your problem is solved.

Check the I2C in the loop and use mills not delay(); This became oblivious in the code you did not post.
