I'm trying to run a machine learning model on stm32l4r9 and NXP RT500 microcontroller. the MCU can not suppor Android or any other OS on a PC. Do I have to write machine learning frameworks in C from scratch to implement this problem ?
I saw some friends using tensorflow lite for micro to solve this problem . When I tried to replicate their approach, I found that the version of TensorFlow I could find didn't match theirs. Which case can I refer to more appropriate?
Hi Chen,
Regarding your first solution to the problem. I think it makes sense, because you may need a Machine Learning model that trains on a powerful device then utilizing the trained model in your low-powered computing devices (i.e. to employ them in your IoT application) and then transfer the trained model to the device with MCU. For instance, save weights' matrix of a trained neural network and hard code them in your device application and then write a simple forward function in order to use it. (Note: you can investigate many open-source ML libraries to quickly develop your code)
Regarding TensorFlow lite, I believe that if your microcontroller series supported, you would be able to use it on your device. But, it may need some effort, maybe reacquired to TF Lite from the source. This situation happens to me about two years ago. I had an RPi 3 and want to use PyTorch in my project. However, at that time PyTorch was not available for my device. So, I had to compile it by myself and it takes a lot of time and effort for me.
I hope I could give you a little guidance

Hi dear if want to implement the model on real time you should try on Raspberry Pi it would be better than MCU
Dear Remi,

In general, there is no need to write frameworks in C.
