STM32 TensorFlow Lite Micro Demos

Collection of STM32 projects making use of Tensorflow Lite Micro. Examples inspired by the TinyML Book.

Toolchain:

CMake-based. See our template: https://github.com/alxhoff/STM3240G-EVAL-TensorFlow-Hello-World

Supported Examples

• Hello World

  based on tensorflow/lite/micro/examples/hello_world

• Micro Speech

  based on tensorflow/lite/micro/examples/micro_speech

• MNIST

  based on alxhoff/STM3240G-EVAL-TensorFlow-MNIST

Supported Boards

• STM32F413H-Discovery (disco_f413zh)
• STM32F769I-Discovery (disco_f769ni)

Please consult the manufacturer's website for specs and datasheets.

Running

git clone https://github.com/PhilippvK/stm32-tflm-demos

You need to also pull the sub-repos where the actual examples are stored.

git submodule update --init --recursive

Then switch into the folder where the example you want to deploy is stored. Do not worry about the recursive argument, we have only linked our repos, which are essential in this case.

cd examples/hello_world

OR

cd examples/micro_speech

OR

cd examples/mnist

Then:

mkdir build
cd build
cmake -DTF_COMMIT=37c2bf5016fcbed261476386eced503e907cdc01 ..
make
make flash

Other make targets we provide include make debug and make convert (to convert the *.tflite file into tfite_micro_compiler sources).

Compatibility

Due to recent updates of the TF Source tree which have not been implemented for the TFLM Compiler, you have to use Commit 37c2bf5016fcbed261476386eced503e907cdc01 or earlier when cloning the TF repositiory via CMake:

cd build
cmake -DTF_COMMIT=37c2bf5016fcbed261476386eced503e907cdc01 ..

If there are new changes for patched files in the TF Source Tree, they will probably not be merged with the modified file or patches might get overwritten. If something like this occours, please remove the build/_deps/tf-* directories and the CMakeCache.txt and try again!
