ubit_uTensor_demo
Yotta build repository for a CNN to be deployed on the Microbit. This project uses uTensor-cli to compile the Tensorflow model into c++ files, and uses the uTensor kernels for execution. The CNN was found using NAS, and this work has been published to arxiv.
Instructions
This project was built in a Docker container. Make sure you have docker installed. I recommend just pulling the image I created for this and running everything in there. I included both the protobuf file for the CNN model, as well as the output c++ files from utensor-cli. These instructions will just assume you just use the pre-existing files for simplicity.
docker pull patrickthomashansen/yotta:initial
#docker run -ti -v PATH_TO_REPO:/home/ patrickthomashansen/yotta:initial bash
docker run -ti -v `pwd`/build:/home/build patrickthomashansen/yotta:initial bash
cd /home
git clone https://github.com/mbartling/ubit_uTensor_demo.git && mv ubit_uTensor_demo/* .
yotta target bbc-microbit-classic-gcc-nosd
yotta build
Then copy the file PATH_TO_REPO/ubit_uYensor_demo/build/bbc-microbit-classic-gcc/source/ubit-utensor-demo-combined.hex onto your microbit to run inference. If it succeeds, it will display a the predicted class on its LED display. Otherwise, the LED display will scroll with a sad face and error code.
