This whole I2C coding is totally new to me. Can you please
elaborate what this means. Do I need to move over into some
other folder?

I'm unsure if this helps. From my understanding SCL gets toggled 
high/low for each transferred bit during an operation. This data block 
may not be intercepted by other consumers
