3.3 UNICODE FRAME

Unlike the previous pixel-based version, MicroGraph LED can manage the Unicode protocol for

displaying non-ASCII 2-byte characters, as for example Chinese, Japanese, Cyrillic, etc.

3.3.1 GRAPHICAL UNICODE FRAME SYNTAX AND COMMAND TABLE

The transmission protocol is completely identical to the Graphical Frame (GRAPH Protocol, see

par. 3.2), with the exception of the transmission of the Data area, where the single characters

must be sent specifying that they are 2-byte characters and ending the string with an ETX Unicode

character (0x2403). Then the ETX (0x03) ASCII character must be sent anyway, just like for other

protocols. It is important to remember to use one of the Unicode fonts (7 or 8).
