This was a great tutorial. The comments rightfully speak accolades. I was able to follow along without having to keep going back and the code worked perfectly. I was able to adjust the code to work with a Raspberry Pi Pico. Thank you. I look forward to more lessons from you.

This is great for learning Micropython. I assume very similar code would work on the pyboard and the new Pi Pico.

Special thanks to Kevin Thomas who wrote a MicroPython driver class for the MPU6050! Check it out here: github.com/mytechnotalent/MicroPython_MPU6050

Hi，can I use int.from_bytes function? Read 2 bytes then change bytes into int with int.from_bytes

I’m guessing that a D1 Mini would work just the same since it’s the same ESP8266 chip, right?

Love your tutorials. 2 questions. Why not create the device drivers as classes? Second question would you be open to creating a tutorial for the APDS-9960 with a detailed breakdown of how to custom create the Gesture Dectection, Color Sense and Gesture sensing? This would really solidify people who would like to contribute to the MicroPython community to write device drivers as there are literally NONE out there other than the work you have done.

@metalmancytech 3 жыл бұрын

Thank you for the feedback! I haven't made the device drivers as classes simply because the structure of my guides is to build an understanding of the concepts, not necessarily to optimize usage. However, I think that creating device drivers using classes is a good idea that I will definitely consider for my future guides. It's funny that you mention the APDS-9960. I was very close to using this sensor instead of the MPU6050, but I settled on the IMU because, in my opinion, it is more straightforward and easy to understand. I probably will make a video featuring the APDS-9960 soon. Your feedback has given me some new ideas. I really appreciate you taking the time to leave a thoughtful comment.

Hi, I got stuck with my esp32wroomdevkit1 . Have issues importing i2c. Any clue? Cheers

@metalmancytech 4 жыл бұрын

I just got out my ESP-WROOM-32 and made sure it was flashed with the latest version of MicroPython (1.12) and tried importing I2C from machine and had no problem. I will just say to make sure that "I2C" is capitalized. Below is the exact import statement I made: from machine import I2C Feel free to reply here if you have more details on the problem or it still isn't working.
