when placed (printnewstr(35,120, ORANGE, &FreeSerifItalic12pt7b, 1, "ADC1"); ) somewhere else ,it wont give error (undefined reference to 'FreeSerifItalic12pt7b') but will happen Hard fault and CPU stops
If use this font FreeMonoBold12pt7b and/or FreeMonoOblique12pt7b and disable FreeSerifItalic12pt7b and some other, everything works fine
