-- `GPIO 1`：UPS 输入电压检测，使用 `ADC 0`；
-- `GPIO 2`：电池电芯电压检测，使用 `ADC 0`；
-- `GPIO 3`：UPS 输出电压检测，使用 `ADC 0`；
+- `GPIO 1`：UPS 输入电压检测，使用 `ADC 1`；
+- `GPIO 2`：电池电芯电压检测，使用 `ADC 1`；
+- `GPIO 3`：UPS 输出电压检测，使用 `ADC 1`；
 - `GPIO 4`：蜂鸣器模拟信号输出，使用 `CHANNEL 0`, `TIMER 0`；
 - `GPIO 5`：工作状态指示灯信号输出；
 - `GPIO 6`：UPS 输出控制信号，适用于 P-MOS 开关；
