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!
