Simultaneous operation of the Adafruit DRV2605L Haptic Motor Controller and IMU Sensor on the XIAO nRF52840 Sense

[YANG2]

By connecting the XIAO nRF52840 Sense with the Adafruit DRV2605L Haptic Motor Controller, we are implementing a function that allows the vibration motor to vibrate when a specific value is sensed by the imu sensor.
However, since both the Adafruit DRV2605L Haptic Motor Controller and the imu sensor use i2c, the imu sensor is not working, is there a solution?

The circuit diagram is as below

+) Should I implement I2C priority between the two within Arduino code?

Hi there,

SO, I2C may need the pull-up resistors Does your DRV board have them?
What is the address of the DRV board ? does it differ from the IMU’s? it may be conflicting Addresses (i.e. set the same)
If you post the code using the code tages above “</>” paste it in there.

A similar configuration is used in a Parkinson’s Glove for finger tip therapy in a study of Vibration effects on dyskinesia by MIT
