Last night I shut everything down including unplugging the breadboard on which the Micro sits. This morning I plugged the USB cable back into the Micro, turned on the computer and the program, which previously had to be reloaded before it would run, started immediately. No changes to anything had been made. I would really like to know what is going on here. I need to have a reliable system, not one that works when it feels like it.
Also, I ran a program to reveal the state of some of the pins on the Micro and they all appear to be set to high. If they were floating, would they not be randomly high and low?
I appreciate the advice that the pull ups are required on the I2C lines.
