NeoPixel
======

外部RGB灯带控制类指令

class NeoPixel(pin, n, bpp=3, timing=0)
-------------

**描述：** 构建对象

.. image:: /images/blocks/NeoPixel/class.png
:scale: 80 %

参数：

- ``pin`` - 输出引脚
- ``n`` - LED灯的个数
- ``bpp`` - bpp=3，默认为3元组RGB；bpp=4，对于具有3种以上颜色的LED，例如RGBW像素或RGBY像素,采用4元组RGBY或RGBY像素
- ``timing`` - 默认等于0,为400KHz速率；等于1，为800KHz速率


NeoPixel.write()
-------------

**描述：** 把数据写入RGB灯珠中


NeoPixel.fill( (r, g, b) )
-------------

**描述：** 填充所有灯珠颜色及亮度， r、g、b 为颜色亮度值，范围值为0~255

bme280
======

bme280环境传感器指令。

bme280是一款集成温度、湿度、气压，三位一体的环境传感器。具有高精度，多功能，小尺寸等特点。

* 温度检测范围：-40℃~+85℃，分辨率0.1℃，误差±0.5℃
* 湿度检测范围：0~100%RH，分辨率0.1%RH，误差±2%RH
* 压力检测范围：300~1100hPa
* 湿度测量响应时间：1s

.. Attention::

掌控板预留bme280芯片位置未贴片,默认配置的掌控板是不带bme280环境传感器,需留意!


bme280.temperature()
-------------

**描述：** 返回温度值,单位摄氏度

.. image:: /images/blocks/bme280/bme280.png
:scale: 80 %


bme280.pressure()
-------------

**描述：** 返回大气压值,单位Pa


bme280.humidity()
-------------

**描述：** 返回环境湿度,单位%


示例
