Propeller Custom Character Example
Define a custom character using the code example below. First, set the baud rate on your Serial LCD to
19,200. Then, load the code below into your Propeller and load RAM or EEPROM. You will see a
diamond character appear on the screen. Note: the FullDuplexSerial.spin object is included with the
Propeller Tool software.
