i2cdetect -l
List all available I2C busses:i2cdetect -y 9
Immediately scan the standard addresses on I2C bus 9 (i2c-9), using the default method for each address (no user confirmation):i2cdetect -F 1
Query the functionalities of I2C bus 1 (i2c-1):i2cdetect -r "SMBus I801 adapter at efa0" 0x10 0x17
Scan addresses 0x10 to 0x17 on the I2C bus named "SMBus I801 adapter at efa0", using the "receive byte" method, after user confirmation:
