器件型号：MSPM0L1306 主题中讨论的其他器件： SysConfig
您好！
我正在使用早期的 MSPM0L1306样片设计概念验证。 它使用4个 PWM 来驱动电机的绕组。 4个 PWM 的配置方式相同、只是一个 PWM 为控制律生成中断。
该工程使用 SysConfig 进行 MCU 配置。
当我运行代码时、没有来自其中一个 PWM 对(TIMG1)的信号。 所有其他 PWM 均按预期工作。
SysConfig 文件如下：
/**
* These arguments were used when this file was generated. They will be automatically applied on subsequent loads
* via the GUI or CLI. Run CLI with '--help' for additional information on how to override these arguments.
* @cliArgs --device "MSPM0L130X" --package "VQFN-24(RGE)" --part "Default" --product "mspm0_sdk@0.57.00.00"
* @versions {"tool":"1.15.0+2826"}
*/

令人惊讶的是、最终引脚多路复用部分中不存在 TIMG1、这就解释了原因。 但是、这种方法的缺失很奇怪、在文本模式下编辑 SysConfig 字段来手动添加它并不能解决问题。
SysConfig 不会指示引脚属性有任何冲突、并且器件表示中突出显示的功能是正确的。
不知道为什么这个 PWM 没有输出？
提前感谢、
