If Core Debug Level is at DEBUG, a confusing debug message will be emitted if the I2C transaction takes longer complete than the calculated minimum time. This original debug message was just to prove that this new i2c code could correctly handle SCL stretching or interrupt latency issues. This delay is not a problem, or an error. Usually it is caused by a higher priory interrupt starving the i2c ISR. Usually WiFi is the culprit. As long of this delay is within the configured timeout (by default 50ms, or can be set with Wire.setTimeOut(milliseconds);) no problem will occur and the transaction will successfully complete.
