KEIL RTX MANUAL PDF

The RTX kernel can be used for creating applications that perform multiple functions or tasks simultaneously. While it is certainly possible to create real-time applications without an RTOS by executing one or more tasks in a loop , there are numerous scheduling, maintenance, and timing issues that can be solved better with an RTOS. For example, an RTOS enables flexible scheduling of system resources like CPU and memory, and offers methods to communicate between tasks. The RTL.

This is useful for large complex applications, where different jobs are implemented as tasks. In this case, the basic framework is different because the functions from the stand alone framework are moved into tasks.

When the timings are not correct, the application might fail to complete certain functions. For example, requests may retransmit too fast, or the waiting timeout might expire before receiving a valid response from a remote server. All rights reserved.

Since the task is not needed after initialization is complete, the task can be terminated. It must have the lowest priority in the system. The interval time should be the same as set in the configuration file. This means they must not be interrupted and called again from another task. All TCPnet-related functionality should be collected in a single networking task.

All callback functions are executed from the networking task. Use the kernel event , semaphore , and mailbox functions to communicate with other tasks.

This section demonstrates an example of using the RTX kernel for a simple application. The application must perform two activities. The first activity must continuously repeat 50 ms after the second activity completes. The second activity must repeat 20 ms after the first activity completes. Hence, you can implement these activities as two separate tasks, called task1 and task In this example, task1 starts first. Hence, task1 must create task2.
