This section provides details on using libmraa in Python to interface GPIOs, PWM, I2C and SPI available on LinkIt Smart 7688 development board. The address was probed but no chip answered. I have interfaced with the three INA3221 and the TMP451 on the kit. One end goes into the connector at the end of a. Sure they do. The python SMBus and the I2C-tools which has the SMBus driver had to be installed on the raspberry pi. I/O header. Users who manually downloaded the new drivers reported. sudo apt-get install python-smbus i2c-tools Enable the I2C kernel module in the Raspberry Pi: sudo raspi-config Now, enable I2C kernel module in: Advanced Options -> I2C -> Would you like the ARM module. When the UDP stream is turned on, the I2C driver seems to repeatedly time out after anywhere between 3 and 15 seconds.
