I have received this display SGL12864 COG with an ST7565 driver.
I am struggling with the wiring as I would like to connect it via SPI (which the doc says is possible).
According to the datasheet attached, you need to have “S/P” Low to enable serial, but I can’t find this “S/P” as a separate pin.
Has this anything to do with the Power Supply voltage 3.3V or 5V by any chance?
in any case, any experience and or ideas would be welcome.
