Here is the code I am using to initialize the OLED, per the instructions 
in the data sheet. I am using the 3-wire SPI configuration, and I have 
set BS0 and BS1 correctly.

For reference, here is the exact OLED I bought:

http://www.buydisplay.com/default/graphic-oled-display-module-3-2-inch.html

And here is my code:

void Initial(void) {
    PINRESETHIGH;
    timer_delay(5); /* in miliseconds */
    PINRESETLOW;
    timer_delay(20);
    PINRESETHIGH;
    timer_delay(5);

    Write_Command(0xA6); /* All off or normal, Data sheet is inconsitent 
*/


    Write_Command(0xFD); /*SET COMMAND LOCK*/
    Write_Data(0x12); /* UNLOCK */
    Write_Command(0xAE); /*DISPLAY OFF*/
    Write_Command(0xB3); /*DISPLAYDIVIDE CLOCKRADIO/OSCILLATAR 
FREQUANCY*/
    Write_Data(0x91);
    Write_Command(0xCA); /*multiplex ratio*/
    Write_Data(0x3F); /*duty = 1/64*/
    Write_Command(0xA2); /*set offset*/
    Write_Data(0x00);
    Write_Command(0xA1); /*start line*/
    Write_Data(0x00);
    Write_Command(0xA0); /*set remap*/
    Write_Data(0x14);
    Write_Data(0x11);
    Write_Command(0xB5); /* Set GPIO */
    Write_Command(0x00);
    Write_Command(0xAB); /* Funtion selection */
    Write_Data(0x01); /* Selection external vdd */
    Write_Command(0xB4); /* Enable External VSL */
    Write_Data(0xA0);
    Write_Data(0xFD);
    Write_Command(0xC1); /* Set contrast current */
    Write_Data(Contrast_level);
    Write_Command(0xC7); /* Master contrast current control*/
    Write_Data(0x0F);
    Write_Command(0xB9); /* Select default linear grey scale table */
    Write_Command(0xB1); /* SET PHASE LENGTH */
    Write_Data(0xE2);
    Write_Command(0xD1); /*Enhance driving scheme capability*/
    Write_Data(0x82);
    Write_Data(0x20);
    Write_Command(0xBB); /*SET PRE-CHANGE VOLTAGE*/
    Write_Data(0x1F);
    Write_Command(0xB6); /*SET SECOND PRE-CHARGE PERIOD*/
    Write_Data(0x08);
    Write_Command(0xBE); /* SET VCOMH */
    Write_Data(0x07);
    Write_Command(0xA4); /* normal display or all off, not sure which */
    Clear_Ram();
    timer_delay(200);
    Write_Command(0xAF); /*display ON*/
    return;
}

void Write_Command(unsigned char cmd) {
    uint16_t new_cmd = 0x0000; /* 9th bit = 0 for sending command */
    new_cmd |= cmd;
    sendMessageSPI2(new_cmd);
    return;
}


void Write_Data(unsigned char dat) {
    uint16_t new_data = 0x0100; /* 9th bit = 1 for sending data */
    new_data |= dat;
    sendMessageSPI2(new_data);
    return;
}



void main(void) {
    BOARD_Init(); /* Init code for my personal board */
    INITPIN29; /* Initialize the reset pin */
    Gui_Init(); /* Initializes SPI, Timers, and empty arrays */
    Write_Command(0xA6); //--all Display off
    Initial();
    while (1) {
        printf("ON!\n");
        Write_Command(0xA5); //--all display on
        timer_delay(5000);
        printf("OFF!\n");
        Write_Command(0xA6); //--all Display off
        timer_delay(5000);
    }
}


NOTE:

The OLED will not even turn on, not once. No screen flicker, nothing. I 
have triple checked everything on the hardware side over and over again, 
so I am convinced that it is software. Any help would be appreciated.

Thanks!
