# 未來板MicroPython編程5：引腳

## 未來板MicroPython編程5：引腳

### 導入未來板庫

需要先導入未來板的庫才可以使用未來板的硬件。

```
from future import *
```

### 05: 引腳類

#### 1. 引腳初始化

```
MeowPin(pin,mode)
```

pin為引腳，例如P1，P2。

mode為模式，有4種模式：

1. 數位輸入：’IN’
2. 數位輸出：’OUT’
3. 模擬輸入：’ANALOG’
4. 模擬輸出：’PWM’

#### 2. 數位讀取

```
getDigital() 
```

#### 2使用範例

```
from future import *
# 數位讀取=['P0','P1','P2','P3','P8','P9','P12','P13','P14','P15','P16']
p0 = MeowPin('P0','IN')
print(p0.getDigital())
```

#### 3. 數位寫入

```
setDigital(val)
```

#### 3使用範例

```
from future import *
import time
# 數位寫入=['P0','P1','P2','P6','P7','P8','P10','P13','P3','P9','P14','P15','P16']
p0 = MeowPin('P0','OUT')
while 1:
    p0.setDigital(1)
    time.sleep(1)
    p0.setDigital(0)
    time.sleep(1)
```

#### 4. 模擬讀取

```
getAnalog(width)
```

width為解像度，可以選擇10位(0\~1023)或12位(0\~4095)。默認為12位。

#### 4使用範例

```
from future import *
# 模擬讀取=['P0','P1','P4','P12', 'P3', 'P14', 'P15', 'P16']

p0 = MeowPin('P0','ANALOG')
print(p0.getAnalog())
print(p0.getAnalog(width=10))
```

#### 5. 模擬寫入

```
setAnalog(val)
```

可以寫入0\~1023。

#### 5使用範例

```
from future import *
import time
# 模擬寫入=['P0','P1','P2','P3','P8','P13','P14','P15','P16']

p0 = MeowPin('P0','PWM')
while 1:
    for i in range(1023): 
        p0.setAnalog(i)
        time.sleep_ms(1)
    for i in range(1023,0,-1): 
        p0.setAnalog(i)
        time.sleep_ms(1)
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://sharinghub.kittenbot.hk/mcu/futureboard/micropython/api5.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
