Nordic nRF54L15 SoC对包含电池监测、中断处理和电源轨控制的定制 nPM1300 示例

1：以下是适用于 nRF Connect SDK (NCS) 的基于 Zephyr 的示例应用程序，展示了：

• 读取电池电压和状态
• 处理来自 nPM1300 的中断（例如，电池或电源轨事件）
• 控制电源轨（通过 GPIO 启用/禁用）

使用方法：

1. 将文件放置在您的 NCS 项目中（例如，在 src/ 、 boards/ 和根目录下）。
2. Build for your board:  为您的板卡构建：

west build -b nrf54l15dk_nrf54l15
west flash
