Getting Started with TI-RTOS: Chapter 7—using tasks

In this video, Eric Wilbur and Scott Specker of Embedded Advantage describe the objectives, agenda, and lab goals for Chapter 7 of the Getting Started with TI-RTOS workshop. 

Chapter 7 covers these topics and answers these questions:

Task Topology and Signaling

• What is the topology of a TI-RTOS Task?
• How does the signaling mechanism work to unblock a TI-RTOS Task?
• How are TI-RTOS Tasks Scheduled?
• What is a TI-RTOS Task’s group priority ranking among other thread types?

Task API

• What are the Task API and their basic uses?
• Can you describe the basic Task function calls that I might need in my application and the benefits of each?

How to Create Tasks

• How do you create a Task statically? Dynamically using the heap?

How to use Error Block

• What is Error Block and how do you use it properly?
• What happens if you use NULL instead of a properly initialized Error Bock in a MOD_create() function call?
• Is there an alternative to using Error Block?
• How does Error_IGNORE work?

Scheduling Tasks

• How are Tasks scheduled in TI-RTOS Scheduler?
• When do Tasks start running?
• Is there no Task_post()?

Scheduling Strategies

• What are the common thread scheduling models in the industry?
• Compare/Contrast the thread scheduling methods.

Lab 7A and 7B: Using Tasks

• Program Tasks to blink an LED
• Program Two Tasks to blink an LED
• How does Task_create() work?
• How do you use Task_sleep(); ?
