  1. Ah, yes - thanks. I should have paid more attention to the manual! Thank you for looking into this and providing the answer.
  2. Hi Jon, Thanks for the reply. See answers, below - 1) I have the display working with the FRDM-K64F microcontroller. All is functioning well and I have been able to implement everything I need, except changing the font size. 2) I have tried running MtdsDemo1 on an Arduino Uno (i.e. using the standard code in the Arduino IDE, downloaded from the Digilent website). Looking through this sketch, it looks like it only sets the font size to hfntMedium and does not attempt to render out any text using this font. I looked at the return value from mtds.GetFont(hds) after setting the font to hfntMedium and it correctly returns 0xC3300003 (which, according to MtdsDefs.h, is the correct value). So, the Set/GetFont calls work fine - it's only when you try to render with these fonts that an error occurs. I've attached a shortened version of MtdsDemo1, where I've modified test21 (there are only two tests in this version - 1 & 21). Basically, it renders out some text using hfntConsole, then sets the font to hfntMedium and then tries to render this. Doing so causes the display to reset, as described in the original post.

  3. Hi, I'd like to use different font sizes on the MTDS display. MtdsDefs.h defines a number of font sizes, but none of these, other than hfntConsole, seem to work. Interestingly, two different errors occur when trying to render text using these fonts, depending on the font size selected. The fonts hfntMedium, hfntLarge & hfntXLarge cause the display to go into a re-sync state. I had a look through the MTDS libs and it's MtdsWaitUntilShieldDone(), called by mtds.cpp, which times out and throws an lSyncError. The fonts hfntXSmall & hfntSmall don't cause an error, but no text is rendered to the display.
