https://devzone.nordicsemi.com/f/nordic-q-a/3011/interrupt-driven-twi-masterI see there have been some issues with TWI in early revs of silicon, but looking at SDK 6 I see the twi_master_hw uses the silicon hardware to read/write the I2C device, but no example of an interrupt driven version is provided.
