Wokwi NMEA Checksum

Testing out the Wokwi Arduino simulator by running my NMEA checksum sketch on it.

nmea-checksum.ino is the Arduino source code. The two HEX files were obtained by going to the Arduino IDE, pasting the sketch code in and pressing Sketch > Export Compiled Binary and then Sketch > Show Sketch Folder. After the compile, the two HEX files appear there.

To-Do

Figure out why the USART is not being called at all

The program output is empty with either of the files.
