Since its release, Arduino has become more than just a development platform; it has become a culture built around
the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has
opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world
application. This combination makes Arduino a perfect environment for school students, seasoned developers, and
designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by
developers in a more advanced Setting. Going beyond projects, this book provides examples that demonstrate concepts
that can be easily integrated into many different projects and provide inspiration for future ones. The focus of this book
is as a transition from the intermediate to the professional.

Computer science as an academic discipline began in the 1960’s. Emphasis was on
programming languages, compilers, operating systems, and the mathematical theory that
supported these areas. Courses in theoretical computer science covered finite automata,
regular expressions, context-free languages, and computability. In the 1970’s, the study
of algorithms was added as an important component of theory. The emphasis was on
making computers useful. Today, a fundamental change is taking place and the focus is
more on a wealth of applications. There are many reasons for this change. The merging
of computing and communications has played an important role. The enhanced ability
to observe, collect, and store data in the natural sciences, in commerce, and in other
fields calls for a change in our understanding of data and how to handle it in the modern
Setting. The emergence of the web and social networks as central aspects of daily life
presents both opportunities and challenges for theory.

一建立STM32cubeMX工程1.建立新工程，選擇芯片STM32F302CCTx2. 在Pinout 中時鐘配置為高速外部時鐘， UART配置為異步通信， cube 會自動分配引腳。3.Clock Configuration 中配置如下4.configuration 中點擊USART1可進入配置在USART1 configuration 中Parameter Settings 可以配置波特率，發送數據字長，奇偶校驗位和停止位等。NVIC Setting 可以配置中斷優先級。5.生成keil 軟件代碼點擊工具欄中的齒輪按鈕，可以選擇代碼的開發平臺， ok 結束。（文件保存路徑一定要是全英文的）進過了我們一系列的配置， cube 會為我們自動生成keil 軟件的代碼，代碼中包括工程所需的固件庫，配套的頭文件，啟動文件及用戶文件。在main.c 中包括了我們工程所需外設的初始化，包括了系統時鐘初始化，中斷初始化， GPIO初始化， USART1初始化， HAL庫初始化。我們只需要在main.c 中添加我們自己的代碼就可以了。二keil 軟件代碼及HAL庫使用UART_HandleTypeDef huart1；生成的代碼中有聲明一個USART處理的結構體HAL庫中串口的數據收發有四個函數HAL_StatusTypeDef HAL_UART_Transmit(UART_HandleTypeDef *huart, uint8_t *pData, uint16_tSize, uint32_t Timeout);HAL_StatusTypeDef HAL_UART_Receive(UART_HandleTypeDef *huart, uint8_t *pData, uint16_tSize, uint32_t Timeout);指針huart 指向我們之前定義的USART處理結構體， 我們將在函數中對結構體中的參數進行操作。pDate 是我們自己定義的數據發送接收緩存， Size 發送接收數據個數， Timeout 超時持續時間。UART狀態的結構體：我們在發送接收函數中要經常對USART的狀態進行判斷，以便我們對函數結構體中的參數進行操作
