## LDC1612寄存器配置
### **1. 软件复位 (RESET_DEV)**
- **寄存器地址**: 0x1C
- **写入值**: 0x8000
- **字段解析**
- **Bit 15 (RESET_DEV)**: 写1触发硬件复位完成后自动清零。

### **2. 进入休眠模式 (CONFIG)**
- **寄存器地址**: 0x1A
- **写入值**: 0x2801
- **字段解析**(按位分解):
| Bit位 | 字段名 | 值 | 功能说明 |

| 5-0 | Reserved | 000001 | 保留位(默认值) |
### **3. 配置通道0时钟分频 (CLOCK_DIVIDERS_CH0)**
- **寄存器地址**: 0x14
- **写入值**: 0x1002
- **字段解析**
| 字段名 | 位域 | 值 | 功能说明 |
|--------------------|-----------|-------|--------------------------|
| CH0_FIN_DIVIDER | Bits 15-12 | 0x1 | 传感器分频系数=1不分频 |
| Reserved | Bits 11-10 | 0x0 | 保留位 |
| CH0_FREF_DIVIDER | Bits 9-0 | 0x002 | 参考分频系数=2f_REF=40MHz/2=20MHz |
### **4. 设置通道0转换时间 (RCOUNT_CH0)**
- **寄存器地址**: 0x08
- **写入值**: 0x04D6 (十进制1238)
- **计算公式**
\[
t_{C0} = \frac{(0x04D6 \times 16)}{20\text{MHz}} = 991\mu s
\]
### **5. 设置通道0稳定时间 (SETTLECOUNT_CH0)**
- **寄存器地址**: 0x10
- **写入值**: 0x000A (十进制10)
- **计算公式**
\[
t_{S0} = \frac{(0x000A \times 16)}{20\text{MHz}} = 8\mu s
\]
### **6. 配置通道0驱动电流 (DRIVE_CURRENT_CH0)**
- **寄存器地址**: 0x1E
- **写入值**: 0x9000
- **字段解析**
| 字段名 | 位域 | 值 | 功能说明 |
|--------------------|-----------|-------|--------------------------|
| CH0_IDRIVE | Bits 15-11 | 0x12 | 驱动电流值=18对应Rp=6.6kΩ查表9 |
| CH0_INIT_IDRIVE | Bits 10-6 | 0x00 | 初始电流值(未使用) |
| Reserved | Bits 5-0 | 0x00 | 保留位 |
### **7. 多通道扫描配置 (MUX_CONFIG)**
- **寄存器地址**: 0x1B
- **写入值**: 0x820C
- **字段解析**
| 字段名 | 位域 | 值 | 功能说明 |
|--------------------|-----------|-------|--------------------------|
| AUTOSCAN_EN | Bit 15 | 1 | 启用自动扫描模式 |
| RR_SEQUENCE | Bits 14-13 | 00 | 扫描顺序Ch0→Ch1 |
| Reserved | Bits 12-3 | 0x020 | 保留位(默认值) |
| DEGLITCH | Bits 2-0 | 0x4 | 去抖动滤波器带宽=3.3MHz |
### **8. 退出休眠并启动转换 (CONFIG)**
- **寄存器地址**: 0x1A
- **写入值**: 0x1601
- **字段解析**(关键位):
| Bit位 | 字段名 | 值 | 功能说明 |
|-------|-----------------------|-----|--------------------------|
| 13 | SLEEP_MODE_EN | 0 | 退出休眠模式 |
| 9 | REF_CLK_SRC | 1 | 使用外部时钟CLKIN=40MHz|
| 12 | RP_OVERRIDE_EN | 1 | 启用Rp覆盖固定驱动电流 |
### **关键参数总结表**
| 寄存器名 | 地址 | 写入值 | 核心功能 |
|----------------------|-------|--------|----------------------------|
| RESET_DEV | 0x1C | 0x8000 | 强制复位设备 |
| CONFIG (休眠) | 0x1A | 0x2801 | 进入配置模式 |
| CLOCK_DIVIDERS_CH0 | 0x14 | 0x1002 | 通道0时钟分频设置 |
| RCOUNT_CH0 | 0x08 | 0x04D6 | 通道0转换时间=991μs |
| SETTLECOUNT_CH0 | 0x10 | 0x000A | 通道0稳定时间=8μs |
| DRIVE_CURRENT_CH0 | 0x1E | 0x9000 | 通道0驱动电流=18约1.5mA |
| MUX_CONFIG | 0x1B | 0x820C | 启用双通道扫描Ch0→Ch1 |
| CONFIG (启动) | 0x1A | 0x1601 | 退出休眠,启用外部时钟 |
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。
---
## **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);
```
