10 Questions
What is the potential consequence of poorly designed embedded code?
Undefined state = BAD MCU interpreted negative values as positive values
How does writing code for an embedded system differ from writing code for a PC system?
Embedded system is resource constrained; Use hardware call stack; Limited call stack on a PIC; Headless (generally runs without a display unit); Use only LEDs / 7 segment displays to indicate status
What are some reasons for poorly designed embedded code?
Acceleration pedal pushed in too far; Stack overflow condition; Sign bit 'flipped'; Developers did not anticipate this; Two’s complement calculations continue
What can happen if an embedded system interprets negative values as positive values?
Full throttle acceleration and the driver can do nothing to stop this
What is the consequence of approaching writing code for an embedded system like a PC system?
Impossibl
What is the potential consequence of a stack overflow condition in embedded code?
The stack overflow condition can lead to unpredictable behavior and system crashes.
What can happen if an embedded system interprets negative values as positive values?
The MCU may interpret negative values as positive values, leading to incorrect calculations and potential system malfunctions.
What are some challenges of writing code for an embedded system compared to a PC system?
Writing code for an embedded system requires resource-constrained programming, limited call stack, and often no display unit.
Why is it important for embedded code to anticipate and handle undefined states?
Undefined states can lead to unexpected behavior and errors in the system.
What are some potential consequences of approaching writing code for an embedded system like a PC system?
Approaching writing code for an embedded system like a PC system can result in impractical or impossible implementation.
