Reference no: EM133363801
QEMU Implementation - Show results of emulated code in QEMU. Can use print statements or other debug output as needed to represent lights and sensors. Must use utsname and display machine name during installation. Must execute on armv7l architecture.
Programming - Multitasking: Multitasking with C and the BeagleBone Black
Update your traffic signal program to be multithreaded:
One thread for each of the traffic signals
Add a wait sensor sensor at each direction - there should be one thread for these as well
Implement this with a push-button
If a light is red but the corresponding wait sensor is triggered (i.e. the button is pushed and held) for 5 seconds, the light should cycle to green without waiting the full 2 minutes
Requirements: Implement the above updates in C using pthreads and mutexes Wait sensor threads should update a wait timer that the light threads can read. Use mutexes to synchronize the data access
Test code first with your emulator - be sure to print the utsname information during initialization
GPIO pins should be configurable - use #define statements to declare the pin numbers so that your code can be tested by professor or TAs
Ensure code compiles with zero warnings
Run the MISRA code check against your code. Fix as many warnings as applicable / possible. Give a short justification for why you can't fix the remaining ones.
BONUS Problems:
a. Implement the same program in Rust
b. Implement the same program in Ada (verison 95 or above)
