[参考译文] LAUNCHXL-CC1352P：如何在 SysConfig 中启用/禁用高 PA

您好、Elias、

实际上、之所以会发生这种情况、是因为这是 E2E 帖子所涉及的问题。 我意识到我之前发送给您的说明是错误的(关于定制板设置)。

同样、您必须在 SysConfig 中切换项目、使其使用自定义板。 但这次使用"LAUNCHXL-CC1352P1"。 此时、我假设您遇到的错误是"  You must _imple_rfDriverCallbackAntennenSwitching_se_generated_ti_drivers_config_c_in_debug_folder_OR_SysConfig 预览./syscfg/ti_drivers_config.o。"。

为了修复该错误，请将以下代码复制粘贴到 simple_peripheral.c (从原始 simple_peripheral 项目的 ti_driver_config.c 复制)中：
