Assessment 2 - Microcontroller Project

Code, comments and logical structure

• 0.5 pts Majority of functions have descriptive comments or are named in such a way that explains the function's intent
• 0.5 pts Inline comments relevant and easy to understand and used where appropriate
• 0 pts Not divided into appropriate functions (repeated code sections) / modules using different files.
• 0.5 pts General structure tidy, succinct, and clear
• 0.5 pts Variables mostly scoped appropriately, but with some deviations from best practice, such as overuse of global variables or having unused variables or unnecessary memory allocation

Use of pre-defined bitmasks and group configurations

• 0.5 pts Use of pre-defined bitmasks
• 0.5 pts Use of pre-defined group configurations

Integer types and appropriate arithmetic operations

• 1 pt Only fixed-width integers defined in stdint.h were used
• 0.5 pts No integer division was used
• 0.5 pts No floating point values or operations were used

State machine usage

• 0.5 pts Appropriate use of enumerated type(s) in a switch-case statement(s) (char switch cases are ok).
• 0.5 pts Default cases are defined in all state machines to handle invalid states appropriately.
• 1 pt State machine/s have been fully implemented and have appropriate states, especially for the main program execution.

Efficient coding practices

• 0.2 pts 3. Unnecessary reads from, or writes to, registers are avoided
• 0.1 pts 4. Buzzer frequencies are appropriately varied and the buzzer is efficiently enabled/disabled
•  0.1 pts 5. LED segments are controlled via an interrupt-driven SPI
• 0.1 pts 6. The potentiometer position is efficiently read and appropriately converted to an interpolation of its position
• 0.3 pts 8. Related conditional statements are consolidated effectively
• 0.3 pts 9. Conditional expressions/statements are correctly identified and implemented
