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 if im going the right way around it. Below is the current function to print out font:
void GLCD_WriteChar(char charCode)
{
unsigned char fontColumn;
for(fontColumn = 0; fontColumn < FONT_WIDTH; fontColumn++)
GLCD_WriteData(font5x7[((charCode - FONT_OFFSET) * FONT_WIDTH) + fontColumn]);
GLCD_WriteData(0);
}
void GLCD_WriteString(char * string)
{
while(*string)
{
GLCD_WriteChar(*string++);
}
}
This is the font header file used:
#define FONT_OFFSET 32
#define FONT_WIDTH 5
static const unsigned char font5x7[] =
{
0x00, 0x00, 0x00, 0x00, 0x00,// (space)

I get the idea behind this function - so have tried to use it for the larger fonts, the code below is my attempt at achieving this, see the attatched header file for font information.
void GLCD_WriteChar_18(char charCode)
{
unsigned char fontColumn;
for(fontColumn = 0; fontColumn < FONT_WIDTH_18; fontColumn++)
GLCD_WriteData(font18[((charCode - FONT_OFFSET_18) * FONT_WIDTH_18) + fontColumn]);
GLCD_WriteData(0);
}
Looking for someone to point me in the right direction :)!
Thanks in advance
