Quickstart - Use .NET to drive a Raspberry Pi Sense HAT
The Raspberry Pi Sense HAT (Hardware Attached on Top) is an add-on board for Raspberry Pi. The Sense HAT is equipped with an 8×8 RGB LED matrix, a five-button joystick, and includes the following sensors:
- Barometric pressure
This quickstart uses .NET to retrieve sensor values from the Sense HAT, respond to joystick input, and drive the LED matrix.
- Raspberry Pi that supports ARM v7 instructions with Raspberry Pi OS. Raspberry Pi OS Lite (64-bit) is recommended.
- Sense HAT
Prepare the Raspberry Pi
raspi-config command to ensure your SBC is configured to support the following services:
For more information on
raspi-config, refer to the Raspberry Pi documentation.
Attach the Sense HAT
With the Raspberry Pi device powered off, attach the Sense HAT. Power on the Raspberry Pi and launch the Bash shell once it boots. You may use SSH or connect the Raspberry Pi to a display.
From the shell, ensure the latest version of Git is installed on your Raspberry Pi. Run the following commands:
sudo apt update sudo apt install git
The commands use the Advanced Package Tool command to:
- Download package information from all configured sources.
- Install the Git command line tool.
Run the quickstart
From the shell, run the following command:
. <(wget -q -O - https://aka.ms/dotnet-iot-sensehat-quickstart)
The command downloads and runs a script. The script:
- Installs the .NET SDK.
- Clones a GitHub repository that includes the Sense HAT quickstart project.
- Builds the project.
- Runs the project.
Observe the console output as sensor data is displayed. The LED matrix displays a yellow pixel on a field of blue. Holding the joystick in any direction moves the yellow pixel in that direction. Clicking the center joystick button causes the background to switch from blue to red.
