TFLite support

[costa-victor]

Hello all,

I've been playing with TFLite for ESP32 using the ESP-IDF recently and I was interested to contribute and bring this to Moddable environment as I believe it would be an interesting feature to have.

Any ideas or suggestions are very welcome, thank you in advance!

Approach 1

This is the approach I have in mind which I believe it would work even though it seems to require some good effort to make it happen.

1. Take the ESP-TFLite component
2. Create an JS interface to bind the C functions into JS

Approach 2

I'm not sure how much functions I will have to integrate into this new JS module to bring the TFLite to Moddable, because of that I thought in another approach which I'm not sure if it would work.

I found a TFLite library in JS already, therefore the interface with the ESP-TFLite which is in C wouldn't be required. Do you think it would work?

Thank you in advance and best regards.

Agreed!

"Approach 1" seems the most practical.

Probably not. The documentation of that notes:

This library is a wrapper of TFLite interpreter. It is packaged in a WebAssembly binary that runs in a browser.

The Moddable SDK doesn't provide WebAssembly and certainly isn't a browser. ;) Even if it did run, it seems like it could be quite a bit slower than running natively.
