ESP8266Arduino & SD ...
Posted: Wed May 20, 2015 8:12 am
Hi to All That's my first post here...
I've just downloaded new 0.0.5 ESP8266-Arduino version of IDE and, looking a bit around, I've seen an interesting new subdirectory "...\esp8266\libraries\SD" and, moooore interesting, "...\libraries\ESP8266WebServer\examples\SDWebServer\...ino".
Is it true ? It's working ? Because, as far as I now, SD library is still waiting SPI... (as written in this post: viewtopic.php?f=27&t=2156 ).
So, if this miracle is TRUE, I have some questions... Wiring SD - ESP ? 1/4 dataline ? SPI interface should be GPIO 6-11 ... but, clock speed ? Moreover... is there something like "SPI_HALF_SPEED" in Arduino, to reduce SPI clock ???
And finally... Where to find more indeep docs about ?
