Got issues with init for 128x32

[dsimonet]

I got issues with cheap 128x32 oled module.

solved with this init sequence :

uint8 cmdbuf[] = {
    0x00,
    SSD1306_DISPLAYOFF,                 //0xAE
    SSD1306_SETDISPLAYCLOCKDIV,         //0xD5
    0x80,
    SSD1306_SETMULTIPLEX,               //0xA8
    DISPLAYHEIGHT - 1,
    SSD1306_SETDISPLAYOFFSET,           //0xD3
    0x00,
    SSD1306_SETSTARTLINE | 0x00,         //0x40
    SSD1306_CHARGEPUMP,                 //0x8D
    0x14,
    SSD1306_MEMORYMODE,                 //0x20
    0x00,
    SSD1306_SEGREMAP | 0x1,             //0xA0
    SSD1306_COMSCANDEC,                 //0xC8
    SSD1306_SETCOMPINS,                 //0xDA
    0x02,
    SSD1306_SETCONTRAST,                //0x81
    0xcf,
    SSD1306_SETPRECHARGE,               //0xD9
    0xf1,
    SSD1306_SETVCOMDETECT,              //0xDB
    0x40,
    SSD1306_DISPLAYALLON_RESUME,        //0xA4
    SSD1306_NORMALDISPLAY,              //0xA6
