    Hi everyone, I am working on temperature measuring gadget using SSD1306 OLED 128 x 64 pixels as display unit, bought on Aliexpress.
    After I successfully finished I2C communication with my PIC24 microcontroller, I had to make some character patterns. For this purpose
    I created small utility for windows - character generator.
    I am attaching exe file believing that it can be useful also for anybody else. I made it in Visual Basic Express (.NET installed is necessary).

    Here is simplest mandatory configuration stream required to be send before any GDDRAM stream feeding:

    8D 14 AF 20 01 21 00 77 22 00 03

    Description:
    8D 14 AF - for charge pump and display on
    20 01 - setting for vertical addressing mode (my exe tool generates data for vertical mode only ! maybe later I will improve it for more flexibility)
    21 00 77 - column start and end address
    22 00 03 - page start and page end address

    After that OLED should be ready to display GDDRAM data (in my case does.)

    I do always send data in stream (Co byte set to 0), regardless of that if I am sending just one byte or byte stream. It still works well !
    Enjoy !
