Example:
The example below is “C” source code to send a group of special characters.
void SendSpecialCharacters( void )
{
// Define the array to hold the 64 bytes
char special_chars[ ] =
{
0x86, 0x89, 0x88, 0x9E, 0x88, 0x8D, 0x92, 0x80,
// £
0x87, 0x88, 0x9e, 0x88, 0x9e, 0x88, 0x87, 0x80,
// euro_image
0x9F, 0x91, 0x91, 0x91, 0x91, 0x91, 0x91, 0x80,
// pi_image
0x84, 0x8A, 0x8A, 0x91, 0x91, 0x91, 0x91, 0x80,
// lambda_image
0x9F, 0x90, 0x90, 0x90, 0x90, 0x90, 0x90, 0x80,
// gamma_image
0x84, 0x8A, 0x8A, 0x91, 0x91, 0x91, 0x9F, 0x80,
// delta_image
0x8C, 0x92, 0x92, 0x96, 0x91, 0x99, 0x96, 0x90,
// ß
0x84, 0x8A, 0x80, 0x91, 0x91, 0x93, 0x8D, 0x80,
// û
};
char buf[ 66 ];
sprintf( buf, "G%s\r", special_chars );
WriteToFD( buf );
}
To use one of these characters in an LCD Message or as the Currency Symbol you replace
the standard ASCII character with the character 0x01 (‘\1’) to 0x08 (‘\8’).
For example to send the message, “Your total is £1234.56” you would send the message
with the following “C” string:
“Your total is \11234.56”
