The module is a lab assignment to better understand the TI DSP/BIOS TSK and SEM modules.

Introduction

This lab module will help you become familiar with the TI DSP/BIOS TSK module and SEM module.

Laboratory

Part 1

  • In this part we will create two tasks that will have the same priority and will run independent of each other.
  • Follow the procedure in Code Composer Studio v4 DSP/BIOS Project to create a new CCS DSP/BIOS project. Name the project tsklab . Your project should have a DSP/BIOS configuration file named tsklab.tcf .
  • Create a LOG object by right clicking on Instrumentation->LOG and selecting Insert LOG. Change the name to trace . Set its properties to have a length of 128 and be a fixed buffer.
  • Create two TSKs with the following properties
  1. Name: TSK0 , priority: 1, function: _funTSK0 .
  2. Name: TSK1 , priority: 1, function: _funTSK1 .
  • Create a main.c file and include a main function that does nothing.
  • In the main.c file make functions for your TSKs, funTSK0 and funTSK1 . Each function should print to the trace LOG object once at the beginning of the function to indicate that the particular TSK is starting and once at the end of the function to indicate that the particular TSK is ending.
  • Add code to each task that loops 5 times and prints to trace the task number and the loop number each time through the loop. It should look something like:
TSK0 Number 0 TSK0 Number 1...
  • The basic structure of main.c should be:
#include<std.h>#include "tsklabcfg.h"void main() {}void funTSK0() {/* code here */ }void funTSK1(){ /* code here */}
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.

Part 2

  • In this part we will change the tasks so that they yield to each other within their loops.
  • 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. Each yields to the other in their loop.
  • Copy the main.c file from above to a new file main2.c . Exclude the main.c from your project build.
  • Change the code so that the two tasks yield to each other within the loop. Put a print statement before the yield and one after the yield so you will know when the function has completed the loop. Do this for subsequent parts of this lab also.
  • Start the debug session.
  • Open the log view by selecting Tools->RTA->Printf Logs .
  • Run the program and record the results.

Part 3

  • In this part we will change the tasks so that one is a higher priority than the other. They yield to each other in their loops.
  • 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. Each yields to the other in their loop.
  • This part will still be executing main2.c .
  • Set TSK0 to 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.
  • Does the execution appear different from part 2?

why is communication effective
Dakolo Reply
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment

because it helps many people around the world to understand how to interact with other people and understand them well, for example at work (job).

Isn't practices worldwide, be it psychology, be it science. isn't much just a false belief of control over something the mind cannot truly comprehend?

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
