Hi,

I have this adafruit Oled display: OLED Breakout Board - 16-bit Color 1.27 w/microSD holder [EYESPI Connector] : ID 1673 : $29.95 : Adafruit Industries, Unique & fun DIY electronics and kits.

Now at the back of the display module i have closed (solded) paths for 3 pin SPI.
I wil not be using sd card only the dislpay.

I have looking the whole day for the correct wiring for 3 pin spi but was not abble to find right info.

Question is witch 3 pins on the display do i have to use to connect to my microcontroller (wemos d1 mini) https://wiki.wemos.cc/products:d1:d1_mini

Have only 3 pins left on the wemos D5 D6 and D7

Hope some can help me out. Any comment is welkom!

This are the pin names on the display form left to right (looking at the back):

GND
VIN
3vo
CD
MISO
SCS
OCS
RST
DC
CLK
MOSI

My goal is to use the dsplay with as little pins as possible.

thanks
N

Your link should be: OLED Breakout Board - 16-bit Color 1.27 w/microSD holder [EYESPI Connector] : ID 1673 : $29.95 : Adafruit Industries, Unique & fun DIY electronics and kits

It needs a minimum of 4 signal pins: mosi (data in), clk (clock), cs (chip select) and dc (data control).

However, if you are already using spi for another device, some pins can be shared between devices.

The wiring is here.
