Hi Steve,
I wonder if the blocking of the interrupts can cause the I2C requests to be missed.
It may be better to use the flag-based approach as this will be non-blocking although the data sent on the I2C bus will be from request n-1, but this should be okay.
It may also be worthwhile adding a peak value detection so that the values are useable for SSB operation, although this may already be done in the main sbitx firmware.
73, Dave?
