器件型号：TMS320F28379S
Thread 中讨论的其他部件：TMS320F28335、 controlSUITE、 C2000WARE、 SysConfig

尊敬的 TI：

我已经为 TMS320F28335制作了标量控制代码、我在其中使用了 f2833xpwm.h 驱动程序文件。我必须对 TMS320F28379S 执行相同的操作、但无法找到任何 f2837xpwm.h 或类似文件。请告诉我如何操作。

您好 Pratyush、

该文件位于：C：/ti/C2000/controlSUITE/device_support/F2837xS/V210/F2837xS_headers/include/F2837xS_epwm.h

如果您使用的是 controlSUITE、我只想让您知道 controlSUITE 未得到维护。所有新器件和错误修复都在 C2000Ware SDK 中完成。因此、我建议您在新项目中使用 C2000Ware SDK。可从此处下载：

https://www.ti.com/tool/C2000WARE

如果您已经使用 C2000Ware SDK、则可以在以下位置找到该文件：

C：/ti/C2000/C2000Ware_4_01_00_00/device_support/f2837xs/headers/include/F2837xS_epwm.h

谢谢、此致、

桑托什

您好、Santosh、

我正在使用 f2833xpwm.h 中的 PWM_init_macro、f2803xpwm.h 中也存在此类文件类型、但 f28379s 没有此类库文件。这是 f2833xpwm.h 的代码 f28379中是否有类似之事？

您好 Pratyush、

这些宏不适用于较新的器件。如果这是新器件、我建议使用最新的 C2000Ware、它支持所有外设的 SysConfig (基于 GUI)配置。请看一下。
