[ELMA I2C] "I2C Timer Expired"
Before starting with the transmission of I2C frames towards the VME board we are testing basic functionality of ELMA firmware.
So, I connected to ELMA without CONV-TTL-BLO connected to it. In this case it is expected that firmware detects no acknowledge of the first I2C. It regularly happens and notifies it as "Not Acknowledged!"
However, there're times in wich instead of receiving a "Not Acknowledge" replied is gotten a "I2C Timer expired" message through the serial console.
What is the meaning of this message?
