Blinky Sample

The Blinky sample demonstrates how to build and deploy a simple Ocre container that allows you to interact with device hardware, namely flashing an LED. This is a good introduction to understanding how Ocre containers can perform basic I/O operations.

Building the Blinky sample

The following steps will guide you to build the blinky sample.

1. Move into the blinky directory (found in samples).

   cd blinky
   

2. Next, build the blinky sample using the following commands:

   mkdir build && cd build
   cmake -DWASI_SDK_DIR=/opt/wasi-sdk -DCMAKE_TOOLCHAIN_FILE=/opt/wamr-sdk/app-sdk/wamr_toolchain.cmake ..
   make
   

This will create a container image called blinky.nbx that we can then deploy to our device.
