I have some questions about SPI port of ESP8266 .
I get from the internet esp8266 from olimex a few weeks before. I want to do some small projects with it, I need to use spi port of it, unfortunately I could not do it. When connect probe to the clock pin of the esp8266 from olimex I get noisy signals. I never see such a clock signal before. Then I tried these same things with esp01, also same problem available here.
After nodemcu board I found, there is no problem with this board. I can use its spi port ,
my question How ı can use spi port of esp8266 from olimex ?? Is there any way to use it ?
You can give me link to study .
thanks for help...
