#6024 Hi All,
I'm trying to set up an ESP driving an SPI display without any external arduino. I found few cryptic ports related such as

viewtopic.php?t=657&p=3864

and the much promising sample code from http://bbs.espressif.com/viewtopic.php?f=15&t=56 (hspi overlap demo to drive spi display from "costaud")

my understanding is that the data and clock pins can be taken from the eeprom on the esp-01 board but the CS must be connected to a GPIO but which ?

I was trying to reverse engineer that from the sample code without much success ... Does anyone have a clue on the actual wires connections to get the ESP-01 board control an SPI device ?

Thanks!

#6524 According to pinout here: http://www.electrodragon.com/w/Wi07c#IC_Pin_Defintion

HSPICS is a function of GPIO15
SPICS0 is pin 20 - doesn't seem to be brought out in modules though...
SPICS1 is a function of GPIO0
SPICS1 is a function (with a question mark. hmmm) of GPIO1 - normally used for UART communication.

Not sure how you go about MUX'ing the other things out and the SPI in though...
