APM32F003 低功耗示例 / APM32F003 Low-Power Example

中文 | English

中文说明

演示将 GPIO 配置为上拉输入后，通过 WFI 进入低功耗 Halt 模式，并使用 PD6/KEY1 外部中断唤醒。使用前请核对板级引脚和中断处理。实测功耗会受调试接口、GPIO、电阻和板载器件影响。

使用建议

1. 检查目标 MCU、开发板、SDK 和工具链版本。
2. 阅读工程配置及源码中的引脚、时钟和外设参数。
3. 编译下载前备份现有固件，并在受控硬件上验证。

English

Demonstrates configuring GPIO as pulled-up inputs, entering low-power Halt mode with WFI, and waking through the PD6/KEY1 external interrupt. Verify board pins and interrupt handling before use. Measured current depends on debug interfaces, GPIO states, resistors, and onboard devices.

Recommended workflow

1. Verify the target MCU, board, SDK, and toolchain versions.
2. Review pin, clock, and peripheral settings in the project and source code.
3. Back up existing firmware and validate on controlled hardware before deployment.
