你好
我正在尝试 使用 MCUSW 基址设置1ms 时基。
我发现 PDK 中的测试用例"dmTimerUt"可以正确显示1ms、如下所示：
但是、当我将程序代码移植到 MCUSW 时、 如下所示：
我使用与 PDK 相同的参数、但获取90ms 计时器

修改错误的哪一侧导致了问题？
感谢你的帮助。
您好！
我的第一个想法是、它可能是使用时钟源的问题。 我看到您已注释掉 GptApp_Startup()，您能否将此启动代码包括回并查看您是否看到正确的行为？
谢谢、
埃里克
我已经尝试过您 的建议、但得到与 之前相同的结果、90ms 计时器。
我认为 时钟源也可能是问题所在。 但我不知道如何修改它。
回到这个话题、您是否已解决此问题或您是否仍需要帮助？
此致、
我仍然 没有解决这个问题。 是否可以提供示例代码或其他解决方案？
您是否对计时器寄存器进行了比较以确保配置相同？ 您是否在寄存器中看到任何差异？
