### Pin

| Pin 设备引脚号 | 开发板引脚名 |          功能      |
| ---------------------| -----------------  |--------------------|
|     52                 |LED                   |   LED          |
|     125               |SW8                 |   BUTTON          |

- 示例

```python
from machine import Pin
led = Pin(("LED1", 52), Pin.OUT_PP)
key = Pin(("KEY", 125), Pin.IN, Pin.PULL_UP) 
while True:
    if key.value():
        led.value(0)
    else:
        led.value(1)
```

### I2C

- 硬件I2C示例

| Pin 设备引脚号 | 开发板引脚名 |          功能      |
| ---------------------| -----------------  |--------------------|
|     60                 |J23-5               |   I2C SDA         |
|     59                 |J23-6               |   I2C SCL          |

```python
>>> from machine import Pin, I2C
>>> i2c = I2C(1)
>>> i2c.scan()
[26, 31, 81]
>>> i2c.writeto(0x51,b'\x05')
1
>>> i2c.readfrom(0x51, 2)
b'\xfa\xfa'
```

- 软件I2C示例

```python
>>> from machine import Pin, I2C
>>> clk = Pin(("clk", 59), Pin.OUT_OD)   
>>> sda = Pin(("sda", 60), Pin.OUT_OD)   
>>> i2c = I2C(-1, clk, sda, freq=100000) 
>>> i2c.scan() 
[26, 31, 81]
>>> i2c.writeto(0x51,b'\x05')
1
>>> i2c.readfrom(0x51, 2)
b'\xfa\xfa'
```

### SPI

- 硬件SPI示例

|   设备名称     | 开发板引脚名  |     功能        |
| ---------------------| -----------------  |--------------------|
|     SPI30      |J24-10       |  SPI3 CLK    |
|     SPI30   |J24-9        |  SPI3  MOSI  |
|     SPI30   |J24-2        |  SPI3  MISO  |

```python
from machine import SPI
spi = SPI(30)
spi.write("hello rt-thread!")
```

- 软件SPI示例

| Pin 设备引脚号     | 开发板引脚名  |     功能        |
| ---------------------| -----------------  |--------------------|
|     59           |J23-6        | SOFT SPI CLK |
|     60           |J23-5        | SOFT SPI MOSI |
|     64           |J23-4        | SOFT SPI MISO |

```python
clk = Pin(("clk", 59), Pin.OUT_PP)
mosi = Pin(("mosi", 60), Pin.OUT_PP)
miso = Pin(("miso", 64), Pin.IN)
spi = SPI(-1, 500000, polarity = 0, phase = 0, bits = 8, firstbit = 0, sck = clk, mosi = mosi, miso = miso)
spi.write("hello rt-thread!")
```
