我正在与Cortex M3、Stellaris® LM 3S 6965评估板合作。我正在尝试在工作的oled屏幕上显示文本。但我不知道如何增加文本大小。
有人知道怎么做吗？
我的当前代码：

#include "inc/hw_types.h"
#include "driverlib/debug.h"
#include "driverlib/sysctl.h"
#include "drivers/rit128x96x4.h"

//*****************************************************************************

#ifdef DEBUG

__error__(char *pcFilename, unsigned long ulLine)
{
}
#endif

//*****************************************************************************
//
// Display scrolling text plus graphics on the OLED display.
//

main(void)
{
    unsigned long ulRow, ulCol, ulWidth, ulHeight;
    volatile int iDelay;
    unsigned char *pucRow;
    static char pucHello[] =
    {
        "                      "
        "Current selected timezone: +2 GMT - Brussels"
        "                      "
    };

    //
    // Set the clocking to run directly from the crystal.
    //
    SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN |
                   SYSCTL_XTAL_8MHZ);

    //
    // Initialize the OLED display.
    //
    RIT128x96x4Init(1000000);

    // Simple scrolling text display
    //
    ulCol = 0;
    while(1)
    {
        //
        // Display the text.
        //
        RIT128x96x4StringDraw(&pucHello[ulCol++], 8, 8, 11);

        //
        // Delay for a bit.
        //
        for(iDelay = 0; iDelay < 100000; iDelay++)
        {
        }

        //
        // Wrap the index back to the beginning of the string.
        //
        if(ulCol > 53)
        {
            ulCol = 0;
        }
    }
}
