    Default Help With OLED Display / 128X64 SSD1306

    Hello,

    Buy this Oled screen of 0.96 ", but so far it works.
    I work connecting to the I2C Bus, the Micro is a 18F4550 to 20MHz.

    Oled Display Image and Data Sheet: http://www.ebay.co.uk/itm/0-96-128x6...-/130536921656

    Pins Board:
    3V3 D0 (SCLK)
    RS D1 (SDIN)
    CS D2
    WR D3
    RD D4
    RES D5
    VIN D6
    GND D7

    Connection ProtoBoard:
    D1 (SDIN) => B0 (SDA)
    D0 (SCLK) => B1 (SCL)
    3V3 => 3V3 (VCC)
    VIN unknow 3V3 (VCC)
    GND => GND
    VBAT => +
    BS0 => 0
    BS1 => 1
    BS2 => 0
    *The other pins are not connected (RS,CS,WR,RD,RES, D02 to D7).

    Whatever you are doing, I hope you didn't include the forum commands at the bottom of your code.
