ESP8266 + Micropython: Why do I keep getting the same value with periodic i2c reads?

I am writing some simple code using MicroPython running on a Digistump Oak, which is basically an ESP8266 breakout board. I'm trying to understand the behavior that I see when performing periodic reads of the sensors via i2c. The following code…

MPU6050 only outputs 0x00 on I2C with MicroPython

I've been trying to talk to my MPU6050 with a Pi Pico running MicroPython. I can verify the I2C is working because when running i2c.scan(), I get the MPU6050 address(0x68). However, when trying to read a specific register from the MPU6050, I always…
