V203C8T6?TIM2模块按照正常初始化不能使用,?由于无法进入调试,?无法得知具体信息,?按照一样的代码,驱动TIM3,?TIM4都是能正常使用的。在TIM2定时器更新中断里翻转IO管脚，用逻辑分析仪是无法看到波形的。TIM3要和TIM4一起启动才能正常使用，单独使用TIM3也是不行。TIM4单独使用是可以的。附件是我的测试代码，使用的VSCode +?CMake编译， OpenOCD下载。编译目标是test_tim.elf

麻烦看看是定时器Bug还是代码有问题,?麻烦给一个TIM2,3,4测试代码,?邮箱? 个人信息保护，已隐藏

邮箱: 个人信息保护，已隐藏

您好，附件为CH32V203C8T6 TIM2、3、4同时使用的一个例程，在定时器更新中断中进行IO翻转，可以参考一下，如下图。后续若有问题，可通过邮箱进行沟通（lzs@wch.cn）

CH32V203 C8T6-TIM2、3、4中断.zip

请问动态修改ARR寄存器的值需要注意什么, 还有中断设置需要注意什么, 我测试的时候发现,TIM4在正常工作后, TIM3计数完成一个周期触发Update中断, 然后TIM4莫名其妙不工作了, 但是TIM3是可以继续工作的, TIM3中断里会计算TIM4新的输出频率, 然后更新TIM4的ARR寄存器, 我觉得问题在于动态修改ARR, 数据手册说了ARR在何时加载到CNT, 却没说更新ARR需要什么事项, 按照一般来说是可以随时更新ARR的。

您好，可参考下图，设置好ARR之后再调用TIM_ARRPreloadConfig函数使能一下

终于搞懂了。非常感谢！但还是有以下小问题，希望解答：

1.  中断频率非常高时，定时器也会停止工作，设定计数频率为9MHz时，ARR=10会导致定时器停止工作。我测试过主频144MHz，中断内部执行过程会小于900nS，加上压栈出栈开销，时间应该大于1US，按照中断响应逻辑，同级别的无法抢占，所以第二次Update需要等待第一次的响应完成才会响应，这个造成后果应该是一直在响应Update，不应该造成定时器停止工作。

您好，可将中断函数设置为不同的优先级测试一下是否会有该问题，后续若有问题，可将工程发至我的邮箱（lzs@wch.cn）具体看一下，后续问题也可通过邮箱进行沟通交流。

楼主找到问题了吗，我和你一样，TIM2和TIM1一样的配置，但是就是无法显示波形

楼主找到问题了吗，我和你一样，TIM2和TIM1一样的配置，但是就是无法显示波形

您好，附件为CH32V203 TIM2 PWM输出例程，可以参考一下。使能开始对应定时器通道PWM输出，要注意程序配置，如下图。

CH32V203C8T6 TIM2 PWM.zip

注意管脚复用功能, 我的使用场景用不到PWM, 仅仅用到输出比较中断

有定时器5使用PWM输出的吗，我用的定时器234例程改的没有PWM输出

您好，CH32V203C8T6没有TIM5，只有高级定时器TIM1和通用定时器TIM2、3、4，没有TIM5
