Lab Description:

In addition to the frontal lectures it is possible, per customer needs/request, to include in the course one or several labs.
The labs topics can cover several topics presented in the lectures, for example can dealing with writing programs using the cross development platform tools and OS.
Such labs can greatly help in understanding and mastering the topics that will be covered in the lectures.
While lectures will deal with general theory and principles, the lab assignments will deal specifically with hands-on experience.
Following is a list of possible labs. Of course the specific issues and topics will be determined after discussing them with the customer.

Lab 1- The main purposes of this experiment are: to become familiar with all the hardware (sensors, track, A-D, I/O board, CPU, cage, etc.); to be introduced to TORNADO development environment; and to become familiar with loading and executing code on a target system.

Lab 2 – In this lab you will design, implement, and test a small real time program. This lab is intended to (1) let you become more familiar with both the development environment and with the needs of real time programming, (2) teach you programming with semaphores, (3) expose you to the concept of running multiple tasks, and (4) determine how to avoid collisions.

Lab 3 – In this lab you will investigate different scheduling orders on a series of tasks which must work in a real time environment.
The objective is to understand how to analyze off-line and then implement EDF scheduling on a commercial kernel. You will learn how to organize a task structure, and control the polling of sensors in these circumstances. You will learn how to use watchdog timers.

Lab 4 – In this lab you will investigate the design and implementation of an interrupt service routine for a real time system. This lab is a modification of lab 3. In lab 3 the program used a watchdog timer to react to changes on the track sensors. This can be replaced with an interrupt driven sensor routine. The DIO board can be programmed to generate an interrupt whenever bits on port 0 achieve a programmer specified level. This will allow a user written Interrupt Service Routine (ISR) to execute only when a car passes a sensor. The main objective is to gain a basic understanding of task design and scheduling when using interrupt service routines.
