SPI vs HSPI support

[lonerzzz]

Hi,

I noticed in the README that you reference both SPI and HSPI (spi_no: SPI or HSPI) but in your blog you recommended against SPI use and indicated no further information would be forthcoming due to the complexities of SPI usage. I was wondering if the existence of options for spi_no indicates that your library works without issue with SPI given the constraint that it is shared?

I ask because my use case for SPI requires very infrequent use and PWM usage so I would like to free up the GPIO12-GPIO15 pins on an ESP-12F module.

Thanks,

Jason
