Are there any examples of an interrupt driven I2C read (using restart)?

I actually need to do multiple read-write sequences from interrupts. I saw a previous post and the write was interrupt driven, but the reads were sequential code.

Thanks

I've used interrupt-driven I2C IO to interface the ADS7823 which is an ADC. It happens to use repeated START as well. See if you find the file useful.
