Part 4

  • In this part you will add a semaphore to the program. One task will pend on the semaphore and the other will post to the semaphore.
  • Have in your system two TSKs with the following properties
  1. Name: TSK0 , priority: 1, function: _funTSK0 .
  2. Name: TSK1 , priority: 1, function: _funTSK1 .
  3. TSK0 pends on the semaphore and TSK1 posts to the semaphore in the loop.
  • Have in your system a semaphore with the following properties
  1. Name: SEM0, initial value: 1
  • Name your new main file main4.c .
  • Remove the task yield from each task.
  • Use SYS_FOREVER for the timeout on the pend.
  • Put TSK0 first in the priority list in the configuration file. This will cause it to run first.
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.

Part 5

  • In this part you change the initial value on the semaphore and observe what happens.
  • Have in your system two TSKs with the following properties
  1. Name: TSK0 , priority: 1, function: _funTSK0 .
  2. Name: TSK1 , priority: 1, function: _funTSK1 .
  3. TSK0 pends on the semaphore and TSK1 posts to the semaphore.
  • Semaphore with the following properties
  1. Name: SEM0, initial value: 2, 3 (run multiple times to get these).
  • Change the semaphore initial value to 2.
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.
  • Run the program with different SEM0 initial values.
  • What happens with the different initial values?

Part 6

  • In this part you will make the task that posts to the semaphore a higher priority.
  • Two TSKs with the following properties
  • Have in your system two TSKs with the following properties
  1. Name: TSK0 , priority: 1, function: _funTSK0 .
  2. Name: TSK1 , priority: 2, function: _funTSK1 .
  3. TSK0 pends on the semaphore and TSK1 posts to the semaphore.
  • Semaphore with the following properties
  1. Name: SEM0, initial value: 1
  • Make the task that is posting a higher priority than the other.
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.

Part 7

  • In this part you will make the task that pends on the semaphore a higher priority.
  • Have in your system two TSKs with the following properties
  1. Name: TSK0 , priority: 2, function: _funTSK0 .
  2. Name: TSK1 , priority: 1, function: _funTSK1 .
  3. TSK0 pends on the semaphore and TSK1 posts to the semaphore.
  • Semaphore with the following properties
  1. Name: SEM0, initial value: 2
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.

Part 8

  • In this part you will run the code that is given for each task and then document for each step through the code the state of the tasks and semaphore and any output that is printed.
  • Have in your system two TSKs with the following properties
  1. Name: TSK0 , priority: 1, function: _funTSK0 .
  2. Name: TSK1 , priority: 1, function: _funTSK1 .
  • Put TSK0 first in the priority list in the configuration file. This will cause it to run first.
  • Semaphore with the following properties
  1. Name: SEM0, initial value: 1
  • Use the followng code for your tasks.
void funTSK0() {LOG_printf(&trace,"TSK0 Starting"); SEM_post(&SEM0); LOG_printf(&trace,"TSK0 1"); SEM_pend(&SEM0,SYS_FOREVER); LOG_printf(&trace,"TSK0 2"); SEM_pend(&SEM0,SYS_FOREVER); SEM_pend(&SEM0,SYS_FOREVER); LOG_printf(&trace,"TSK0 3"); SEM_post(&SEM0); LOG_printf(&trace,"TSK0 Finish"); }funTSK1(){ LOG_printf(&trace,"TSK1 Start"); SEM_post(&SEM0); LOG_printf(&trace,"TSK1 1"); SEM_pend(&SEM0,SYS_FOREVER); SEM_post(&SEM0); SEM_pend(&SEM0,SYS_FOREVER); LOG_printf(&trace,"TSK1 2"); LOG_printf(&trace,"TSK1 Finish"); }
  • Fill out the following table as you run your program.

Laboratory write-up

  • For each part of this lab, explain the setup of the objects and what they are doing. Explain the results in great detail showing values for things like the semaphore count and why the task is running.
