通过前面3节的研究，总算把基本的环境搭建好了，接下来移植Grove来获取模块的数据
【创龙TL3562-MiniEVM开发板试用体验】问题1 更换到Ubuntu镜像后，USB识别不了外设
【创龙TL3562-MiniEVM开发板试用体验】问题2 ubuntu镜像，不能获取ip地址
【创龙TL3562-MiniEVM开发板试用体验】问题3 扩展ubuntu文件系统
grove
Grove是由Seeed Studio推出的模块化电子接口标准，旨在简化嵌入式原型开发。它通过标准化4针连接器（防反插设计）替代复杂的面包板跳线，实现传感器、执行器与主控板（如Arduino、树莓派）的“积木式”连接，降低硬件入门门槛。
核心设计理念：
- 模块化：通过统一的4针接口连接传感器、执行器等模块，类似“电子积木”。
- 标准化：接口分为GPIO、ADC、PWM、UART、I2C等类型，确保兼容性。
- 易用性：简化硬件连接流程，降低学习门槛，适合快速原型开发
grove模块
Grove 拥有 300+ 种模块，覆盖传感器（温湿度、光照、火焰）、执行器（电机、继电器）、显示设备（OLED、数码管）、通信模块等，形成“积木式”开发体验
按功能分类的典型模块及用途：
主要应用在开源板上，从8位的Arduino，到32位的raspberry系列、BeagleBone系列等等主流开发板，通过扩展板（如GrovePi+）实现无缝连接
grove库
grove采用分层的设计模式，通过grove.py库，实现上层应用与底层实现的分离，以适应不同的硬件环境
- 应用层：开发者编写逻辑代码，调用Grove库提供的封装函数（如analogRead(pin)读取光传感器）
- 软件库层：主要是指抽象层grove.py，也即Adafrit RKIO层，封装硬件细节，提供跨平台兼容性
- SMBUS，针对I2C，使用pySMBUS和i2ctools库
- 接口层：物理连接：4针统一接口定义，当然了，接口的信号连接对应的信号，如GPIO,I2C,ADC,PWM等：
- 硬件模块层：具体的grove模型模块，输出标准化信号供主控读写
安装BB.GPIO
常见的GPIO库，有raspberry pi 的RPi.GPIO和beaglebone Black的BB.GPIO
在此以BB.GPIO以例子，将其移植到TL3562MiniEVM上
下载
介绍
如上所示，整个文件可以分为3种，
- 一种是通用文件，如constants，定义常量，
- 一种是需要移植适配的，如common.c，c_xxx.c文件
- 一种是py_xxx文件，它会调用c_xxx.c文件，是标准文件，它的存在是为了将c语言转成python接口
而关键的移植适配文件有
- common，定义引脚及转换接口
- event_gpio，定义gpio的输入输出配置，主要是基于/sys/class/gpio
- c_adc，定义adc的输入配置，主要是基于/sys/bus/iio/devices/iio:device0/in_voltage2_raw
- c_pwm,定义pwm的输入输出配置，主要是基于/sys/class/pwm
