Hi,
I'm trying to drive an oled display in 3-wire SPI mode (no D/C line).
I initialize lcdgfx with DC pin set to -1. Display stays black no matter what I try.
#define VSPI_MOSI_PIN 2 #define VSPI_CLK_PIN 15 #define VSPI_CS_PIN 12 #define VSPI_DC_PIN -1 #define VSPI_RST_PIN -1 DisplaySSD1351_128x128x16_SPI display(VSPI_RST_PIN,{-1, VSPI_CS_PIN, VSPI_DC_PIN, 0, VSPI_CLK_PIN, VSPI_MOSI_PIN});
This oled is the only SPI device I have, so I have no way to verify if the problem is in the oled, lcdgfx or the platform. At least with 4-wire SPI the display is working fine.
Is 3-wire SPI supported by llcdgfx
(on the oled pcb, I've set the BS jumper to 1).
Hello Alex Only 4-wire SPI interface is supported by the library.
Best regards
