µC/OS-III

(2)

OSTaskCreate() creates a task to be managed by uC/OS-III. Tasks can be created either prior to the start of multitasking or by a running

task. In this case, the task "AppStartTask" gets created.

(3)

OSStart() starts multitasking under uC/OS-III. This function is typically called from the startup code but calling OSInit().after

(4)

AppTaskStart is the startup task created in

(2)

.

(5)

OSTimeDlyHMSM() allows AppTaskStart to delay itself for a user-specified amount of time (500ms in this case). Rescheduling always occurs

when at least one of the parameters is nonzero. Placing a break-point here can ensure that uC/OS-III is running, it should get hit periodically

every 500 milliseconds.

µC/TCP-IP

Ping Demo

This feature will test µC/TCP-IP capabilities by performing a simple "ping" test on the STM324x9I-EVAL. The configuration for this demo is

based on the IP address, default gateway, and subnet mask of not only the host (computer/device) but also the settings of the client.

The following steps are based on Microsoft's Windows 7™ PC as the host system. These steps may vary based on the

operating system and settings.

The default gateway and subnet mask will become the default gateway and subnet mask necessary for the STM324x9I-EVAL's

configuration. These settings are usually found in as the following #defines:app_net.c
