通过以上配置,设备将按以下流程运行:
1. 复位后进入休眠模式,配置寄存器。
2. 设置通道0的时钟分频、转换时间、稳定时间和驱动电流。
3. 启用双通道自动扫描,设置去抖动滤波器。
4. 退出休眠模式,开始连续转换。
4. 退出休眠模式,开始连续转换。

## **自动校准配置(可选)**
### **适用场景**
- Rp未知或环境变化大时通过自动校准获取初始电流值。
### **操作流程**
1. **设置目标至最大距离**
2. **进入休眠模式**
```c
write_register(0x1A, 0x2801); // SLEEP_MODE_EN=1
```
3. **启用自动校准**
```c
// CLOCK_DIVIDERS_CH0配置分频
write_register(0x14, 0x1002); // FIN_DIV=1, FREF_DIV=2
// 禁用Rp覆盖
uint16_t config = read_register(0x1A);
config &= ~(1 << 12); // RP_OVERRIDE_EN=0
write_register(0x1A, config);
```
4. **启动测量并读取初始值**
```c
write_register(0x1A, 0x1601); // 退出休眠
delay(10); // 等待至少一次转换完成
uint16_t init_value = (read_register(0x1E) >> 6) & 0x1F; // 读取CH0_INIT_IDRIVE
```
5. **写入驱动电流**
```c
uint16_t drive_current = (init_value << 11) | 0x0000;
write_register(0x1E, drive_current);
```
