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.

a. Implement the same program in Rust
b. Implement the same program in Ada (verison 95 or above)
