Reading the temperature

With the device wired and attached, you'll want to try some code on it to confirm we can talk to this device and get data out of it. Let's get some tools installed and make it work.
Installing the software
Before we can start interacting with this device, as with most devices, we will install a helper library to communicate with it. Pimoroni, the suppliers of the ICM20948 module I've suggested, have made a handy library for Python to talk to it. I recommend taking their latest version from GitHub.
Perform the following steps to install it:
Boot up the Raspberry Pi on the robot. This Pi should have been used previously for the motor board and LED shim and have I2C enabled. If not, go back to Chapter 7, Drive and Turn – Moving Motors with Python, and follow the steps for preparing the I2C.
Type in i2cdetect -y 1 to check that you've installed the device correctly. The output should look like this:
```
pi@myrobot:~ $ i2cdetect -y 1
  ...
```
