Hi
Can any one show me how the syntax should looks like??

void upFL()
{
  digitalWrite(FLSolUp, HIGH); 
  u8g.setCursorPos(50, 10);
  u8g.setCursorFont(const u8g_font_cursor 0x93);
}

With this i get error

error: expected primary-expression before 'const'

Hi.
Trying to print symbol from the x11 font group but for somereason i get mixed pixels instead of symbol.
Any suggestions??

  u8g.setFont(u8g_font_7x13_67_75);
   u8g.drawStr(40,40, "0x93");

Look at the examples that come with this library. You have to set up the page before your can do anything with it.

The function's signature is:

    void setCursorFont(const u8g_pgm_uint8_t *cursor_font)

which tells me it wants a pointer to the font, not a constant. You may want a pointer to one of the font tables (u8g_font_data.c)....I can't tell from three lines of code.

Ah git it now.
thanks.

Why do you want to print the string "0x93" on your LCD?

Did you mean u8g.drawStr(40,40, "\x93");?
