When i2c / spi / sdio documentation

[Andrew]

When esp32 will receive all needed documentation for main interfaces?

I feel that there is no producters team and only people who develop it are users of this forum. Without docs and examples this chip is unusable

[Sprite]

I wouldn't say there's no 'producters team' around here. Ivan, Angus and I are regulars on this forum and we're all enginmeers for Espressif.

Documentation got a bit on the backburner because of the crunch to release esp-idf 1.0. I2C and SPI are already being edited as we speak, SDIO will be coming after pretty quickly.
