STemWin V5.26 not displaying extended characters?

Posted on February 02, 2015 at 18:52

I'd like to display the characters on the ''GUI_Font20_1'' font above I have modified the ''Hello World example (STM32Cube_FW_F4_V1.4.0\Projects\STM32F429I-Discovery\Applications\STemWin\STemWin_HelloWorld) with the following changes to BASIC_HelloWorld.c.

/*********************************************************************
*
* MainTask
*/
#define S 117
static const char hiChars1[] = { S, S+1, S+2, S+3, S+4, S+5, S+6, S+7, S+8, S+9, 0 };
#define S 128
static const char hiChars2[] = { S, S+1, S+2, S+3, S+4, S+5, S+6, S+7, S+8, S+9, 0 };
#define S 138
static const char hiChars3[] = { S, S+1, S+2, S+3, S+4, S+5, S+6, S+7, S+8, S+9, 0 };
void MainTask(void) {
GUI_Clear();
GUI_SetFont(&GUI_Font20_1);
GUI_DispStringAt(hiChars1, 0, 0);
GUI_DispStringAt(hiChars2, 0, 20);
GUI_DispStringAt(hiChars3, 0, 40);
GUI_DispStringAt(hiChars1, 0, 60);
while(1);
}

On the screen I get two display lines (with ''uvwxyz{|}~'') with two blank lines in between. I searched the manual (UM03001) for some hint of what I had overlooked and could find nothing. What do I need to do to get the extended characters in the font to display? Thanks!
