I've noticed, that there is new version of ESP8266 module: ESP-12E, which has hardware SPI lines derived on solder pins.
Unfortunately current version of SDK do not provide functions for direct SPI communication. This interface is reserved for external flash chip, but SPI can interface with multiple devices, all you need to do is use another IO pin as additional CS line.
I have to questions:
1) Is there a way to interface another SPI device from ESP-12E module (like SD card or RFID card reader)?
2) Will hardware SPI bus support be added to the SDK in the future?
