User’s Manual 73
This function prints a formatted string (much like printf ) on the LCD screen. Only printable charac-
ters in the font set are printed; escape sequences ’\r’ and ’\n’ are also recognized. All other escape
sequences will be skipped over. For example, nothing will be displayed for ’\b’ and ’t’ .
The text window feature provides end-of-line wrapping and clipping after the character in the last col-
umn and row is displayed.
NOTE: Be sure to execute the
TextWindowFrame
function before using any of the
text-only functions (
TextGotoXY

TextPutChar

TextPrintf

TextCursorLocation ).
