Add air quality monitoring to your project and with an Adafruit CCS811 Air Quality Sensor Breakout. Package i2c-tools. The system configuration parameters, which would traditionally be edited and stored using a BIOS, are stored instead in an optional text file named config. Adafruit 16 Channel Servo Driver with Raspberry Pi Created by Kevin Townsend Last updated on 2019-01-17 09:42:03 PM UTC. I’ll use a temperature and humidity sensor as an example of I2C peripheral. First, install all neccesary tools and some good to have ones. SMBus and Raspbian Stretch Linux; I2C, SMBus and Raspbian Stretch Linux I2cdetect returns a grid of possible addresses with each device displayed as shown in the screenshot below. Turns out that once I figured out how to do it, it was pretty simple to get /dev/i2c-0 to show up on i2cdetect -y 0 (running on Raspbian 4. Link to ADS1015 Link to Raspberry’s Pins. sudo apt install i2c-tools The package has the same name in Fedora, so I would guess other distros as well. Some datasheets list the address in an 8 bit form (7 address bits + R/W bit), while others provide the address in a 7 bit form, with the address in the lower 7 bits. You can then check to see if the Jetson TK1 can detect the LIDAR-Lite v2 address: $ sudo i2cdetect -y -r 1. Miniature OLED display modules are a great way to add a small screen to your Raspberry Pi projects.
