Previous: 7.2 Formatting Command Summary
- The final character position of the LCD screen is used as a system
``heartbeat.'' This character continuously blinks back and forth when
the board is operating properly. If the character stops blinking, the
Handy Board has crashed.
- Characters that would be printed beyond the final character
position are truncated.
printf() command treats the two-line LCD screen
as a single longer line.
- Printing of long integers is not presently supported.
