看门狗可以在hal中进行设置吗

Susan Yang：

请问您使用的是哪款芯片？

Susan Yang：

您可以参考下面的步骤

This is an example which describes the steps to configure dwwd to generate NMI

Step 1:

Create a new project.

Navigate: -> File -> New -> Project

Step 2:

Configure driver code generation:
•Enable GIO driver
•Enable RTI driver
•Disable others

Navigate: -> TMS570LS12x/RM46x/TMS570LS43x/RM42x -> Enable Drivers

Step 3:

Enable RTI Compare 0 interrupt in VIM (Tab VIM Channel 0-31)

Step 4:

Set the compare periods of RTI Compare 0 as 200ms

Navigate: -> RTI -> RTI Compare

Step 5:

Copy the source code below into your sys_main.c or replace sys_main.c with this file.

The example file can also be found in the examples folder: ../HALCoGen/examples

好久没用这个系列了，马上安装HAL配置工具看看。

user5245154：

您好，我问下，RTI这样被用作看门狗，他还同时能当做定时器用吗

Susan Yang：

您是指看门狗定时器？
