Well, today i got my Sainsmart OLED, which i ordered because i thought i broke the chinese OLED while Soldering the Jumper for I2c.
I changed the code to spi
//----- OLED instance #define OLED_MOSI 9 #define OLED_CLK 10 #define OLED_DC 11 #define OLED_CS 12 #define OLED_RESET 13 Adafruit_SSD1306 display(OLED_MOSI, OLED_CLK, OLED_DC, OLED_RESET, OLED_CS);
And i wired everything up (i got a white cable) on my breadboard with a arduino pro mini 3.3v 8mhz OLED -> Arduino 3.3V -> VCC Ground -> GND SDIN -> D9 SCLK -> D10 DC -> D11 RST -> D13 CS -> D12
3.7V from Lipo -> Raw Ground -> GND
and now it looks exactly like the first OLED from China.
What did i have done wrong? I cant imagine i got 2 dead OLEDs in a row. I tested the first one with my Raspi too, and i got the same image. Atleast, i hope they arent dead :) Thanks for every help ~Straw
