Waveshare Jetbot motor library

Hi i had recently purchased the waveshare jetbot for trying out the jetbot examples.
I found out that nvidia uses the adafruit motor hat library for the motor control,so i wanted to try the example codes from the GitHub account of adafruit containing adafruit motor hat library.
i run into this error runtime error: could not determine default i2c bus for the platform.
Please help me

in the RobotTest file i encounter this error

no im still getting the same error

can you please help me in solving this error

Hi rahulsinghrox701 ,

Please refer to below topic to see if can help:

MY jetbot examples work but when i want to try the examples of https://github.com/adafruit/Adafruit-Motor-HAT-Python-Library it shows the error mentioned above.

can anyone help me

Hi rahulsinghrox701,

Thanks for reaching out.

With JetBot we manually specify i2c_bus=1 for the Adafruit_MotorHAT library. See this line

I would guess you want to try adding that parameter to the Adfruit example as well

Please let me know if this helps or you run into any issues.
