The 'D/C' pin would determine the device's I2C address, between 0x7A (high) and 0x78 (low). Checked i2c bus. If the DC pin is connected to ground (GND) then the I2C slave address becomes 0x78. SCL=5 => D1; SPI. So far all of my SSD1306 and SSH1106 OLEDs from Ebay (SPI and I2C variants) did work with u8glib. Finally you can run the File→Sketchbook→Libraries→Adafruit_SSD1306→SSD1306_128x64_i2c example Using with SPI The breakouts are ready for SPI by default, but if you used them for I2C at some point, you'll need to remove the. How to make this I2C OLED screen work? (probably SH1106) libraries but I can't get address of this screen from I2C scanner - it's not answering. #chip mega328p, 16; # option explicit #include #define HI2C_BAUD_RATE 400 #define HI2C_DATA HI2CMode Master #define GLCD_TYPE GLCD_TYPE_SSD1306 #define GLCD_I2C_Address 0x78; dim tmp1, row, py, px, SSD1306SendByte as byte GLCDCLS GLCDDrawString (0, 0, "TEST"); this works; locx = 50: locy = 32 px = 50: py = 24 row = 2 spritebyte = 255 write_sprite_byte; sends byte to 0, 0 not px, row do forever; sub write_sprite_byte; writes byte to display at row and px co-ord for tmp1 = 1 to 6. I already showed you how to connect LCD 16×2 using I2C in a STM32 microcontroller, you can check that out here. Note that this component is for displays that are connected via the I²C Bus. I2C Class in the Reference. Most of the I2C libraries I've seen source code for, including that for the Aruduino, chunk the data in this fashion.
