1.27" 128x96 RGB OLED 3 wire SPI CONNECTION

Post by Kumalix »

Hi,

I have this adafruit Oled display: https://www.adafruit.com/product/1673.

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. ant comment is welcom!

thanks
N

See section 8.1.4 of datasheet:
https://cdn-shop.adafruit.com/datasheet ... on+1.3.pdf
The 3-wire serial interface consists of serial clock SCLK, serial data SDIN and CS#. In 3-wire SPI mode, D0 acts as SCLK, D1 acts as SDIN.
These are labeled on the silkscreen as:
D0 = CLK
D1 = MOSI
CS# = OCS
