MicroPython code already written
- Built-in Python support for all the SoC features. (10K+ Lines of C code)
- Definition of a universal MicroPython Hardware API.
External libraries:
- Blynk: SMTP, MQTT, URLLIB, ONEWIRE, Accelerometer, Event loop MicroPython together with
the universal hardware API allow us to build a large set of powerful, robust, and portable
libraries across hardware platforms.
