Custom characters on phi-panel

You can use all custom characters on phi-panels as long as you are not using them in a long message, which uses custom characters to display the scroll bar on the right.

You can do the following:

When you need to use custom characters, follow the sample code phi_panel_big_show between lines 167 and 189. The last command in that function prints “\eZ~” to the panel to reinitialize the panel’s internal custom characters. Otherwise you will see your custom characters in place of the scroll bar 🙂

You will need the custom character definitions in your code as well so:
The code may be a bit messed up by the blog posting restrictions but you can find original code in the beginning and between lines 167 and 189 of the sample code phi_panel_big_show.

for (byte j=0;j {
Serial.write(ch_buffer[j]|0x80); // Add a 1 to MSB to make sure the custom character definition is always beyond a numerical value of 31 to avoid a confusion with control characters.
}
Serial.write(‘~’);
}
Serial.print(‘\f’); // Clear screen
Serial.print(“Custom character “);
for (byte i=0;i {
Serial.write(i);
}
delay(5000);
Serial.print(“\eZ~”); // Reinitialize phi_prompt since the long message requires custom characters;

}
