Hi guys,

Basically Im working on a project using an ARM STM32 processor on a Keil eval board. Attached to it is a UC1601 GLCD screen.
The problem that im having I want to be able to increase the size of the font, but im not sure how im to go about it - below is the function that is used and a header file that contains the pixel font information that is currently being used for smaller text:

void GLCD_WriteChar(char charCode)
    unsigned char fontColumn;

    for(fontColumn = 0; fontColumn < FONT_WIDTH; fontColumn++)
    GLCD_WriteData(font5x7[((charCode - FONT_OFFSET) * FONT_WIDTH) + fontColumn]);
#define FONT_OFFSET 32
#define FONT_WIDTH	5

static const unsigned char font5x7[] = 
0x00, 0x00, 0x00, 0x00, 0x00,// (space)
0x00, 0x00, 0x5F, 0x00, 0x00,// !
0x00, 0x07, 0x00, 0x07, 0x00,// "

Would be much appreciated if someone could point me in the right direction for a method of achieving this.
