Excelent documentation!
1. The ESP8266 must be set into some kind of slave mode that communicates via SDIO with a host microcontroller. I think this must be done with a a extra piece of software that must be loaded into the ESP8622. It would be great if this piece of software could be loaded into the ESP8266 also via SDIO.
2. The host microcontroller requires a framework or API to send correct commands and data via SDIO to the wifi adapter.
Is anything of this available yet or would I have to begin at zero?
Or can anyone point me to a resource which would help me understand:
- if it can actually be used as an SPI slave
- how to receive SPI data and respond
- which pins should be used
Any help massively appreciated!
