我想在2个 EPWM 通道之间实现相移、例如下面的波形(从简单时基 EPWM 通道获得)：[ syscfg. TI 示例库下载的示例]

我下载了另一个 HRPWM 示例(syscfg)并成功运行、但无法在两个 HRPWM 通道(epwm1A 和 epwm2A)之间建立相移。

我已经从 TI 示例库(示例名称：epwm_ex3_synchronization)中学到了相移设置、并将其相移设置扩展为 HRPWM 配置、但失败了。

我不了解 HRPWM 通道和简单 ePWM 通道之间的基本相移逻辑。

在 TI 示例库中、我没有找到 HRPWM 同步示例、我可以在那里了解它。

您能否检查由 syscfg 工具生成的 HRPWM 相移代码。

请帮助我解决这个 HRPWM 相移问题。谢谢你。
