0.96 oled SPI configuration

[albertobonati]

Hi.
In hardware settings I read:
Init SPI: (Note : Chip Select (CS) config must be done in the plugin)

I know how connet I2C oled, but what about SPI connection to ESP?

I have 6 pins SPI oled:
GND
VCC
SCL:CLK clock
SDA : MOSI data
RST: MOSI data
D/C data/command

thanks
Alberto

SDA and SCL are I2C. MISO and MOSI are described under "Hardware --> SPI Interface" where to connect to.

[albertobonati]

OK... I see this in MEGA version:

Note: CLK=GPIO-14 (D5), MISO=GPIO-12 (D6), MOSI=GPIO-13 (D7)
Note: Chip Select (CS) config must be done in the plugin

But what about CS? Where I have to connect this?

Are you really sure you have the SPI version?
You describe pins for I2C (SDA/SCL)

SPI is using a clk, MISO & MOSI pins and a chip-select line.
I thought the SPI versions had 7 pins: https://www.banggood.com/7Pin-0_96-Inch ... ?rmmds=buy

There is only 1 Pin left: D/C. The "C" could be Chip Select!? Try it. No risk, no fun.

Must not be! Look here:

Well..I have 7 pin version and 6 pins version.
In 7 pin version it's possible to set I2C or SPI interface changing SMD resistor position, I used them but only in I2C mode.
In 6 pins version you can't do this (I think..) and it's only SPI interface, although pin name is SDA/SCL.
My 6 pin version is exactly this:
http://www.rhydolabz.com/displays-c-88/ ... -2260.html

I tryed in I2C mode but don't work.
So I tryed to use it in SPI mode with ESP8266, with Arduino board it work fine but I can see in sketch pin assignament.
In ESP Easy normal version, in hardware page I foun only this:

Note: Chip Select (CS) config must be done in the plugin

In MEGA version a further help:
Note: CLK=GPIO-14 (D5), MISO=GPIO-12 (D6), MOSI=GPIO-13 (D7)
Note: Chip Select (CS) config must be done in the plugin

So I know how to connect SCL, SDA, RST (referring pin names in my board) but don't work, maybe I have to connect DC pin too, but where?
I don't find documentation about this....
Best regards

Have you read the item description from my link above? The solution stand there (you are in advantage if you had read it!)

.....
For the I2C setup it demands a little bit of work on the module. Actually it was one of our customers who shared these simple configuration steps with us, start with resoldering the resistor from position R3 to R1 and then short the R8 resistor with some solder tin (0 Ohm resistor). The R6 and R7 pullup resistors are already soldered, nothing to do there. Once done, the module is ready for I2C communication! The CS Pin is not necessarily needed, so just connect it to GND. The DC Pin selects the address. For standard address wire it to GND. The RES-pin needs a low pulse at startup and high voltage during operation (as in SPI mode), a 100nF capacitor to GND and a 10k res to VCC would be ideal!

Sorry, I did a mistake... this is my module:

https://www.amazon.it/gp/product/B074M9 ... UTF8&psc=1

It look like your at front side, but not at back side...

Maybe you find here a solution....

[albertobonati]

Thanks, but on my arduino it work fine...
I need a solution for ESP8266 and ESP Easy...

I do know the ESP8266 will support SPI displays. I have a adafruit 2.4 inch TFT featherwing and it works with the examples provided. Getting it to wok on ESPEasy is another thing all together. I have been working on it, but I am not sure if this is possible for me. Time will tell....
