7 years ago You could check if the sensor is connected properly to your device. I noticed this behavior on the Edison platform. The device wasn't connected when I ran i2cdetect (-r BUS_NUM). If the device isn't connected i2c calls from PIO will fail.

7 years ago @spitfire88 I assume you didn't run this though adb shell then?
rpi3:/ $ i2cdetect
/system/bin/sh: i2cdetect: not found

6 years ago I have Ginkgo USB-I2C Adapter when i run i2c sample with Resberry Pi 3, it is crashing with following logs:

6 years ago Same problem here. The output of the i2cdetect command is as below;
D:\Android\sdk\platform-tools>adb shell rpi3:/ $ i2cdetect -V /system/bin/sh: i2cdetect: not found

There's no i2cdetect on Android Things. You can list the I2C pins (and other protocols) by using the pio tool: pio list i2c
@RichardisMeok As for the Ginkgo USB-I2C, I don't believe it will work right out of the box. You might need to open your USB device using USBHost APIs, implement the Ginkgo protocol and create a I2C Bus to map the devices connected through USB to the I2C protocol.
Hi, I have BMP 280 sensor from Ada fruit. While running BMP 280 sample with Resberry Pi 3, it is crashing with following logs: 03-25 13:51:04.250 1271-1271/?
