Help me to connect oled SSD1309
I ask for help in setting up Repetier-FW 1.0.4. I have a Ruramps v.1.3, DUE board. I am trying to connect oled SSD1309 to them with the SPI bus. There are no settings for this display in the uiconfig.h file.
Tell me how to configure soft_spi? As I understand it, the display must be turned on in this way. I would be grateful for your help.
