### Pin

| Pin 设备引脚号 | 开发板引脚名 | 功能 |
| -------------- | ------------ | -------------- |
|     7           |      PC13        | KEY 2 |
|     33          |      PC4          | GPIO && LED3 |

- 示例

```python
>>> from machine import Pin
>>> p_out = Pin(("X1", 33), Pin.OUT_PP)
>>> p_out.value(1)              # set io high
>>> p_out.value(0)              # set io low
>>> p_in = Pin(("X2", 7), Pin.IN, Pin.PULL_UP)
>>> p_in.value()                # get value, 0 or 1
```

### I2C

- 软件 I2C 示例

| Pin 设备引脚号 | 开发板引脚名 | 功能 |
| -------------- | ------------ | -------------- |
|     7           |      PC13        | SCLK |
|     33          |      PC4          | SDA |

```python
from machine import Pin, I2C
clk = Pin(("clk", 7), Pin.OUT_OD)    
sda = Pin(("sda", 33), Pin.OUT_OD)   
i2c = I2C(-1, clk, sda, freq=100000) 
i2c.scan()
[81]
```

### SPI
- 软件 SPI 示例

| Pin 设备引脚号 | 开发板引脚名 | 功能 |
| -------------- | ------------ | -------------- |
|     5           |      E6                | CLK |
|     4           |      E5                |MOSI |
|     33          |      PC4               | MISO |

```python
from machine import Pin, SPI
clk = Pin(("clk", 5), Pin.OUT_PP)         
mosi = Pin(("mosi", 4), Pin.OUT_PP)      
miso = Pin(("miso", 33), Pin.IN)         
spi = SPI(-1, 500000, polarity = 0, phase = 0, bits = 8, firstbit = 0, sck = clk, mosi = mosi, miso = miso)
```
