88 eDisplay (OP7200)

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).
