Communicating between ESP8266 and a Microbit via SPI.

Note: this repo is a WIP. Documentation is very poor for SPI support.

The BBC Micro:bit v2 has a Nordic nRF52833 Core variant Arm Cortex-M4 32 bit processor with FPU at 64 MHz.

The ESP8266 has a ESP8266 @ 80MHz with 3.3V logic/power, 4MB of FLASH (32 MBit), Built-in WiFi 802.11 b/g/n.

I'm using an Adafruit Huzzah Feather ESP8266.
