Thank you for your interest in the Intel® Edison Breakout Board.
I have to inform you that code debugging is out of the scope of our technical support team.
Although, I may be able to provide some insight. What I understand from your post is that you can’t get any output from register 0x14. I checked the links you provided (specifically the one showing VL53L0Xtest.py) and saw that accessing register 0x14 has to be done through the bus.read_i2c_block_data() function.
If you have any other update or question related to the Edison module itself, don’t hesitate to contact us.
Have a nice day.
