## AT 指令简介
|
||||
<el-divider></el-divider>
|
||||
AT指令是应用于终端设备与PC应用之间的连接与通信的指令。AT 即Attention。每个AT命令行中只能包含一条AT指令;对于AT指令的发送,除AT两个字符外,最多可以接收1056个字符的长度(包括最后的空字符)。</br></br>
|
||||
|
||||
AT指令集是从终端设备(Terminal Equipment,TE)或数据终端设备(Data Terminal Equipment,DTE)向终端适配器(Terminal Adapter,TA)或数据电路终端设备(Data Circuit Terminal Equipment,DCE)发送的。</br></br>
|
||||
其对所传输的数据包大小有定义:即对于AT指令的发送,除AT两个字符外,最多可以接收1056个字符的长度(包括最后的空字符)。</br></br>
|
||||
每个AT命令行中只能包含一条AT指令;对于由终端设备主动向PC端报告的URC指示或者response响应,也要求一行最多有一个,不允许上报的一行中有多条指示或者响应。AT指令以回车作为结尾,响应或上报以回车换行为结尾。</br>
|
||||
|
||||

# mymqtt
|
||||
|
||||
## Mqtt简介
|
||||
<el-divider></el-divider>
|
||||
MQTT(Message Queuing Telemetry Transport,消息队列遥测传输协议),是一种基于发布/订阅(publish/subscribe)模式的"轻量级"通讯协议,该协议构建于TCP/IP协议上,由IBM在1999年发布。MQTT最大优点在于,可以以极少的代码和有限的带宽,为连接远程设备提供实时可靠的消息服务。作为一种低开销、低带宽占用的即时通讯协议,使其在物联网、小型设备、移动应用等方面有较广泛的应用。</br></br>
|
||||
|
||||
MQTT是一个基于客户端-服务器的消息发布/订阅传输协议。MQTT协议是轻量、简单、开放和易于实现的,这些特点使它适用范围非常广泛。在很多情况下,包括受限的环境中,如:机器与机器(M2M)通信和物联网(IoT)。其在,通过卫星链路通信传感器、偶尔拨号的医疗设备、智能家居、及一些小型化设备中已广泛使用。</br></br>
|
||||
|
||||
## 主要特性
|
||||
<el-divider></el-divider>
|
||||
MQTT协议工作在低带宽、不可靠的网络的远程传感器和控制设备通讯而设计的协议,它具有以下主要的几项特性:
|
||||
|
||||
+ (1)使用发布/订阅消息模式,提供一对多的消息发布,解除应用程序耦合。</br>
|
||||
这一点很类似于XMPP,但是MQTT的信息冗余远小于XMPP,,因为XMPP使用XML格式文本来传递数据。
|
||||
|
||||
+ (2)对负载内容屏蔽的消息传输。
|
||||
|
||||
+ (3)使用TCP/IP提供网络连接。</br>
|
||||
主流的MQTT是基于TCP连接进行数据推送的,但是同样有基于UDP的版本,叫做MQTT-SN。这两种版本由于基于不同的连接方式,优缺点自然也就各有不同了。
|
||||
|
||||
+ (4)有三种消息发布服务质量:</br>
|
||||
"至多一次",消息发布完全依赖底层TCP/IP网络。会发生消息丢失或重复。这一级别可用于如下情况,环境传感器数据,丢失一次读记录无所谓,因为不久后还会有第二次发送。这一种方式主要普通APP的推送,倘若你的智能设备在消息推送时未联网,推送过去没收到,再次联网也就收不到了。</br>
|
||||
"至少一次",确保消息到达,但消息重复可能会发生。</br>
|
||||
"只有一次",确保消息到达一次。在一些要求比较严格的计费系统中,可以使用此级别。在计费系统中,消息重复或丢失会导致不正确的结果。这种最高质量的消息发布服务还可以用于即时通讯类的APP的推送,确保用户收到且只会收到一次。
|
||||
|
||||
+ (5)小型传输,开销很小(固定长度的头部是2字节),协议交换最小化,以降低网络流量。</br>
|
||||
这就是为什么在介绍里说它非常适合"在物联网领域,传感器与服务器的通信,信息的收集",要知道嵌入式设备的运算能力和带宽都相对薄弱,使用这种协议来传递消息再适合不过了。
|
||||
|
||||
+ (6)使用Last Will和Testament特性通知有关各方客户端异常中断的机制。</br>
|
||||
Last Will:即遗言机制,用于通知同一主题下的其他设备发送遗言的设备已经断开了连接。
|
||||
Testament:遗嘱机制,功能类似于Last Will。

# 编译步骤
|
||||
|
||||
## 前言
|
||||
<el-divider></el-divider>
|
||||
<p style="text-indent:2em">本文档将介绍<B>XiUOS</B>分别在基于ARM和RISC-V架构的开发板上的编译、烧录和运行的过程。包括开发板选择及配置初始化、编译命令等信息。
|
||||
</p>
|
||||
|
||||
## 开发板的选择及配置初始化
|
||||
<el-divider></el-divider>
|
||||
<p style="text-indent:2em">在执行编译之前,我们需要先确定<B>XiUOS</B>系统要运行在哪个开发板上,然后针对具体的开发板设置相关的配置信息。</p>
|
||||
|
||||
+ 开发板的选择
|
||||
为了查看<B>XiUOS</B>支持的开发板种类,可以执行以下命令,也可以[查看支持的开发板](/hardwaresupport/arm32/stm32f407-st-discovery.html)。
|
||||
|
||||
$ make BOARD=list
|
||||
+ 配置初始化
|
||||
+ 以stm32f407-st-discovery为例,进行开始系统参数。
|
||||
|
||||
|
||||
|
||||
|
||||
$ make BOARD=stm32f407-st-discovery menuconfig
|
||||
<img src="https://raw.githubusercontent.com/yanyannew/images/branch/stm32_menuconfig.png" />
|
||||
对应的配置信息将存放在board/stm32f407-st-discovery/xsconfig.h头文件中,文件中的选项均以<B>XS_</B>为前缀开头。
|
||||
|
||||
+ 以kd233为例,进行开始系统参数。
|
||||
|
||||
$ make BOARD=KD233 menuconfig
|
||||
|
||||
<img src="https://raw.githubusercontent.com/yanyannew/images/branch/kd233_menuconfig.png" />
|
||||
对应的配置信息将存放在board/kd233/xsconfig.h头文件中,文件中的选项均以<B>XS_</B>为前缀开头。
|
||||
|
||||
## 编译命令
|
||||
通用编译命令, 默认为BOARD=KD233
|
||||
|
||||
$ make [BOARD=<所选开发板>]
|
||||
+ 当 make 命令被执行时,它会扫描当前目录下Makefile或makefile文件找到目标以及其依赖。如果这些依赖自身也是目标,继续为这些依赖扫描Makefile 建立其依赖关系,然后编译它们。
|
||||
+ 创建build目录,目录下包含了各种目标文件、.bin、.elf等文件
|
||||
+ 目标文件,以.o结尾的文件
|
||||
+ .bin 二进制文件
|
||||
+ .elf 可执行文件
|
||||
## 烧录命令
|
||||
+ 基于ARM开发板的烧录命令
|
||||
|
||||
$ sudo st-flash write <生成的.elf文件> 0x8000000
|
||||
+ 基于RISC-V开发板的烧录命令
|
||||
|
||||
$ sudo kflash <生成的.elf文件> -t
|
||||
|
||||

# 内存管理
|
||||
|
||||
## 前言
|
||||
计算机系统中,变量、中间数据一般存放在 RAM 中,只有在实际使用时才将它们从 RAM 调入到 CPU 中进行运算。一些数据需要的内存大小需要在程序运行过程中根据实际情况确定,这就要求系统具有对内存空间进行动态管理的能力,在用户需要一段内存空间时,向系统申请,系统选择一段合适的内存空间分配给用户,用户使用完毕后,再释放回系统,以便系统将该段内存空间回收再利用。</br>
|
||||
|
||||
由于实时系统中对时间的要求非常严格,内存管理往往要比通用操作系统要求苛刻得多:
|
||||
</br></br>
|
||||
1)分配内存的时间必须是确定的。一般内存管理算法是根据需要存储的数据的长度在内存中去寻找一个与这段数据相适应的空闲内存块,然后将数据存储在里面。而寻找这样一个空闲内存块所耗费的时间是不确定的,因此对于实时系统来说,这就是不可接受的,实时系统必须要保证内存块的分配过程在可预测的确定时间内完成,否则实时任务对外部事件的响应也将变得不可确定。
|
||||
</br></br>
|
||||
2)随着内存不断被分配和释放,整个内存区域会产生越来越多的碎片,系统中还有足够的空闲内存,但因为它们地址并非连续,不能组成一块连续的完整内存块,会使得程序不能申请到大的内存。对于通用系统而言,这种不恰当的内存分配算法可以通过重新启动系统来解决,但是对于那些需要常年不间断地工作于野外的嵌入式系统来说,频繁的重启是无法接受的。
|
||||
</br></br>
|
||||
3)嵌入式系统的资源环境也是不尽相同,不同的系统内存大小不同,如何为这些不同的系统,选择适合它们的高效率的内存分配算法,也是一个复杂的问题。
|
||||
</br></br>
|
||||
XiUOS操作系统提供了独特的内存管理分配算法进行内存管理,通过静态内存管理和动态内存管理相结合,保证分配和释放内存的实时性,提高内存的使用率,有效地规避了内存碎片问题,同时增加了内存检索的速度。
|
||||
</br></br>

||||
|
||||
## 内存堆
|
||||
### 静态内存管理
|
||||
#### 静态内存划分
|
||||
静态内存包含2个链表。其中,每个链表都具有block_size静态内存块大小、total_count静态内存块的总个数、free_count空闲内存块的总个数和free_list空闲链表这四个属性。
|
||||
其中block_size属性记录了当前链表中每个静态内存块的大小,
|
||||
total_count属性记录了系统初始化之后分配给该链表中静态内存块的总个数,
|
||||
free_count属性记录了该链表中还可以分配给用户静态内存块的个数,
|
||||
free_list属性则真正指向各个空闲静态内存块。
|
||||
</br></br>
|
||||
下图为静态内存链表的具体情况。图中包括两个静态链表1和2。静态链表头1指向的内存池中存放的静态内存块的大小都是32字节,静态链表头2所指向的内存池中存放的静态内存块的大小都是64字节。此外,系统分别配置了静态链表头1和静态链表头2中静态内存块的total_count个数为256和128。因此,静态链表头1最多可以响应用户256次的小于32字节的内存请求,静态链表头2最多可以响应用户128次的介于33-64字节之间的内存请求,一旦对应的静态内存块分配完了,系统会向动态内存区域寻求内存空间分配。
|
||||
|
||||
<div style="display: flex;justify-content: center;align-items: center;">
|
||||
<img src="./imagesrc/fig1.png" width =100%/>
|
||||
</div>
|
||||
|
||||
#### 静态内存分配
|
||||
在用户发起内存分配请求时,若用户请求分配的内存空间大小小于等于预设的静态内存阈值,且所述静态内存区域有相应空闲的内存块,则从静态内存区域分配相应大小的内存空间。
|
||||
</br></br>
|
||||
在用户发起内存释放请求时,所述分配释放请求解析根据用户提供的内存地址决定后续的操作:
|
||||
</br>
|
||||
如果所述内存地址是不合法的,则直接返回结果给用户。
|
||||
</br>
|
||||
如果所述内存地址是合法地址,分配释放请求解析模块解析所述内存地址所属内存区域,所述内存地址在静态内存区域,则内存分配任务由静态内存管理模块负责;所述内存地址在动态内存区域,则内存分配任务由动态内存管理模块负责。
|
||||
</br></br>
|
||||
|
||||
从静态内存区域分配静态内存块的过程,包括三种情况。</br>
|
||||
+ 当用户请求分配内存大小小于等于32字节,那么分配释放请求解析模块解析该内存大小由静态内存管理模块负责。系统获取静态链表头1,从静态链表头1中获取一个静态内存块返回给用户;</br>
|
||||
+ 当用户请求分配内存大小为33~64字节,那么分配释放请求解析模块解析该内存大小由静态内存管理模块负责。系统获取静态链表头2,从静态链表头2中获取一个静态内存块返回给用户;</br>
|
||||
+ 若所获得的静态链表头是一个空的链表,即没有空闲的静态内存块可用,那么通知分配释放请求解析模块在静态内存区域中内存分配失败。
|
||||
|
||||
#### 静态内存释放
|
||||
当用户请求释放内存,所述内存用ptr表示,释放操作包括三种情况。</br>
|
||||
+ 所述ptr内存地址是不合法的,则直接返回释放操作。</br>
|
||||
+ 所述ptr指向的静态内存块属于静态链表头1管理,则将所述ptr指向的静态内存块放置到链表头1的头部;</br>
|
||||
+ 若所述ptr指向的静态内存块属于链表头2管理,则将所述ptr指向的静态内存块放置到链表头2的头部。
|
||||
|
||||
### 动态内存管理
|
||||
#### 动态内存划分
|
||||
静态内存划分后,剩下的内存区域作为动态内存分配给动态内存区域。动态内存区域管理用到了三种重要的数据结构,分别是已分配动态内存段、空闲动态内存段和动态内存管理数据结构。下图显示了已分配动态内存段和空闲动态内存段这两种数据结构。其中,已分配动态内存包括元数据信息和用户的数据段(用户数据),元数据信息中的size属性记录了该动态内存段的内存大小,prev_size属性则记录了该动态内存段前一个相邻动态内存段的内存大小,从而可以获取前一个相邻动态内存段。用户数据则是分配给用户使用的内存空间。空闲动态内存段的元数据信息具有size、prev_size、prev和next这四个属性,其中,size和prev_size属性与已分配动态内存段的对应属性表示的意义相同,prev属性记录了前一个空闲动态内存段,最后一个next属性则记录了下一个空闲动态内存段。
|
||||
</br></br>
|
||||
<div style="display: flex;justify-content: center;align-items: center;">
|
||||
<img src="./imagesrc/fig2.png" width =90%/>
|
||||
</div>
|
||||
</br></br>
|
||||
下图展示了动态内存区域初始化之后的状态,系统将动态内存区域划分为三个动态内存段,分别是起始地址处已分配动态内存段和结尾已分配动态内存段,中间区域的内存用一个空闲动态内存段记录。
|
||||
</br></br>
|
||||
<div style="display: flex;justify-content: center;align-items: center;">
|
||||
<img src="./imagesrc/fig3.png" width =80%/>
|
||||
</div>
|
||||
</br></br>
|
||||
动态内存管理数据结构是动态内存区域管理中的核心数据结构,用于组织所有的空闲动态内存段。所述动态内存管理数据结构具有total_size、dynamic_start、dynamic_end和freeLists这四个属性,其中,total_size属性用于记录动态内存区域的大小,dynamic_start属性用于记录起始地址处已分配动态内存段,dynamic_end属性用于记录结尾处已分配动态内存段,freeLists属性是一个多级链表,每一级链表记录了内存大小在指定范围的空闲动态内存段。根据空闲内存段的大小,系统判断空闲内存段所属动态链表,然后将空闲内存段插入不同的空闲链表中。</br></br>
|
||||
系统配置空闲链表的个数为10。当动态内存段大小在1-31字节之间,则插入到空闲链表freeList1中,当动态内存段大小在32-63字节之间时,则插入到空闲链表freeList2中,需要特别说明的是,当动态内存段大小大于或者等于8192字节时,都插入到空闲链表freeList10中。如下表所示:
|
||||
|
||||
<div>
|
||||
<table style="margin-left: auto; margin-right: auto; table-layout: fixed;" width = 500 >

|
||||
</table>
|
||||
</div>
|
||||
|
||||
|
||||
#### 动态内存分配
|
||||
系统根据要分配或者要释放的内存段大小计算要操作的内存段链表头,当内存段大小为1 ~ 31字节,那么内存计算单元计算之后将获取空闲动态链表头freeList1,当内存段大小为32 ~63字节,那么内存计算单元计算之后将获取动态链表头freeList2。以此类推。</br></br>
|
||||
当用户请求从动态内存段申请内存时,动态内存管理模块只能有以下几种分配情况:</br>
|
||||
+ 用户请求分配30个字节,freeList1链表中有一个32字节内存大小可以满足用户的需求,之后进行内存块的分割操作,32可以分配为30字节 + 2字节,但是2字节小于系统要求的8字节对齐大小,因此将32字节内存返回给用户;</br>
|
||||
+ 用户请求分配45个字节,并且系统已经知道静态内存区域无法分配。内存计算单元计算45字节对应的空闲动态链表,获取freeList2,freeList2链表中有一个56字节内存大小可以满足用户的需求,之后进行内存块的分割操作,56可以分配为45字节 + 11字节,11字节小于系统要求的8字节对齐大小,因此,除了返回45字节动态内存给用户,还要执行11字节的内存释放操作;</br>
|
||||
+ 用户请求分配8000个字节。内存计算单元计算8000字节对应的空闲动态链表,获取freeList9,freeList9链表中没有空闲动态内存段,没有找到可分配的动态内存段并且freeList9不是最后一级链表,更新链表头到freeList10,freeList10链表中动态内存段可以满足用户的需求,之后进行内存块的分割操作,9000可以分配为8192字节 + 808字节,808字节大于系统要求的8字节对齐大小,因此,除了返回8192动态内存给用户,还要执行808字节的释放操作;</br>
|
||||
+ 用户请求分配6000000个字节。内存计算单元计算6000000字节对应的空闲动态链表,获取freeList10,freeList10链表中没有空闲动态内存段,没有找到可分配的动态内存段并且freeList10是最后一级链表,内存分配操作失败,结束内存分配操作。</br>
|
||||
|
||||
#### 动态内存释放
|
||||
当用户请求释放内存,所述内存用ptr表示。分配释放请求解析模块解析判断ptr所述区域为动态内存区域,则将释放ptr所指向的内存区域到动态内存段中。
|
||||
|
||||
<div style="display: flex;justify-content: center;align-items: center;">

<img src="./imagesrc/fig9.png" width =95%/>
|
||||
</div>
|
||||
|
||||
释放一块动态内存段,上图提供了动态内存段释放和合并的三种情况,其中,每一个动态内存段都包含了两个指针,分别指向前一个相邻内存段和后一个相邻内存段,下面介绍图9展示的三种释放并合并的三种情况:
|
||||
+ 如图中(a)所示,四块动态内存段,其中,A,B,D三段为已分配动态内存段,C为空闲动态内存段。当前,系统要释放内存段B,动态内存管理模块检测到B内存段的后一个相邻C也是空闲内存段,则系统会合并内存段B,C,然后释放BC合并之后的内存段。
|
||||
+ 如图中(b)所示,A,B,C,D四块已分配内存段。系统要释放内存段B,动态内存管理模块检测到B的相邻内存段都是已分配内存段,那么直接释放内存段B。
|
||||
+ 如图中(c)所示,四块动态内存段,其中,A,C是空闲内存段,B,D是已分配内存段。系统要释放内存段B,动态内存管理模块检测到B的前一个相邻内存段A和后一个相邻内存段B都是空闲内存段,那么先合并A,B,C三个内存段形成一个大的空闲内存段ABC,然后释放合并形成的ABC空闲内存段。
|
||||
|
||||
## 内存池
|
||||
内存堆管理器可以分配任意大小的内存块,非常灵活和方便。但其也存在明显的缺点:一是分配效率不高,在每次分配时,都要空闲内存块查找;二是容易产生内存碎片。为了提高内存分配的效率,并且避免内存碎片,XiUOS提供了另外一种内存管理方法:内存池。
|
||||
</br></br>
|
||||
内存池在创建时先向系统预先申请分配一定数量、大小相等(一般情况下)的内存块留作备用。当有新的内存需求时,就从内存池中分出一部分内存块,若内存块不够再继续申请新的内存。

# 线程间通信
|
||||
XiUOS 的线程间通信使用邮箱、消息队列和信号三种方式。下面将分别介绍。
|
||||
|
||||
## 邮箱
|
||||
### 邮箱的工作机制
|
||||
XiUOS 的每一封邮件大小为4字节,也就是一个指针的大小。典型的邮箱应用是,线程或中断服务发送一封4字节长度的邮件到邮箱中,其他的线程可以从邮箱中接收邮件并进行处理。</br></br>
|
||||
当一个线程向邮箱发送邮件时,如果邮箱没满,就将邮件复制到邮箱中。如果邮箱满了并且超时时间设置为0,则返回`-XS_EFULL`;如果超时时间不为0,先将该发送线程挂起,当邮箱中的邮件被取出空出空间后,等待挂起的发送线程被唤醒继续发送。但是如果到达超时时间仍没有空间,则返回`-XS_EFULL`。</br></br>
|
||||
当一个线程从邮箱中接收邮件时,如果邮箱中有邮件,就读出该邮件的内容,并返回XS_EOK。如果邮箱中没有邮件并且超时设置为0,则返回`-XS_ETIMEOUT`;如果超时时间不为0,则将该线程挂在邮箱的等待线程中,有邮件时唤醒。但是如果到达超时时间仍没有邮件,返回`-XS_ETIMEOUT`。
|
||||

|
||||
```C
|
||||
xs_err_t xs_MessageQueueUrgentSend(xs_messagequeue_t mq, const void *buffer, xs_size_t size)
|
||||
```
|
||||
|
||||
发送紧急消息和发送普通消息的区别是:当发送紧急消息时,从空闲消息链表上取下来的消息块不是挂到消息队列的队尾,而是挂到队首,这样,接收者就能够优先接收到紧急消息,从而及时进行消息处理。</br>
|
||||
|
||||
| 参数 | 描述 |
|
||||
| ------ | ------ |
|
||||
| mq | 消息队列对象指针 |
|
||||
| buffer | 消息内容 |
|
||||
| size | 消息大小 |
|
||||
</br>
|
||||
|
||||
```C
|
||||
xs_err_t xs_MessageQueueReceive(xs_messagequeue_t mq,
|
||||
void *buffer,
|
||||
xs_size_t size,
|
||||
xs_int32 timeout)
|
||||
```
|
||||
当队列中有消息时,接收消息。队列中没有消息时,根据超时时间设定进行等待。接收一个消息后消息队列上的队首消息被转移到了空闲消息链表的尾部。成功收到消息返回`XS_EOK`,超时返回`XS_ETIMEOUT`。接收消息失败返回`-XS_ERROR`。
|
||||

## 信号
|
||||
### 信号的工作机制
|
||||
信号是在软件层次对中断机制的一种模拟。XiUOS中提供了信号用作异步通信的方式。</br></br>
|
||||
收到信号的线程对各种信号有不同的处理方法,处理方法可以分为三类:</br></br>
|
||||
第一种是类似中断的处理程序,对于需要处理的信号,线程可以指定处理函数,由该函数来处理。</br></br>
|
||||
第二种方法是,忽略某个信号,对该信号不做任何处理。</br></br>
|
||||
第三种方法是,对该信号的处理保留系统的默认值。</br></br>
|
||||
具体来说,假设其他线程要向线程1通信,则在线程1中安装一个信号并解除阻塞,在安装的同时,规定对该信号的异常处理方式。其他线程给线程1发送信号,触发线程1对该信号的处理。
|
||||
### 函数接口
|
||||
```C
|
||||
xs_sighandler_t xs_InstallSignal(int signo, xs_sighandler_t handler)
|
||||
```
|
||||
该函数用于给当前线程安装一个新的信号。</br>
|
||||
|
||||
| 参数 | 描述 |

||||
| ------ | ------ |
|
||||
| signo | 信号值 |
|
||||
| handler | 设置对信号值的处理方式,可以是用户自定义的函数,`SIG_IGN`或`SIG_DFL` |
|
||||
</br>
|
||||
|
||||
handler的值为`SIG_IGN`时,忽略该信号;</br>
|
||||
handler的值为`SIG_DFL`时,执行信号默认处理函数`_SignalDefaultHandler`;</br>
|
||||
handler为函数句柄时,执行用户函数。 </br>
|
||||
|
||||
```C
|
||||
void xs_MaskSignal(int signo)
|
||||
```
|
||||
该函数用于屏蔽一个信号。</br>
|
||||
|
||||
| 参数 | 描述 |
|
||||

||||
</br>
|
||||
|
||||
```C
|
||||
void xs_UnmaskSignal(int signo)
|
||||
```

|
||||
```
|
||||

|
||||
|
||||
| 参数 | 描述 |
|
||||
| ------ | ------ |
|
||||
| set | 指定等待的信号 |
|
||||
| set | 指向存储等到信号信息的指针 |

### 注意事项
|
||||
+ 模块具有防反接保护,接时只要注意不要把电源接到串口输出线上即可,以免烧坏转换模块或MCU。
|
||||
+ 串口输出为 TTL 电平,测试时请使用 TTL 转 USB 的模块。请勿使用 232 转 USB。
|
||||
+ 模块在平常安静的环境中输出为 50dB 左右。
|
||||
+ 测试时,电源地与串口地一定连通,让信号形成回路,否则测试时,串口软件显示无数据输出。当软件显示有乱码时,把串口测试软件的十六进制显示勾上即可显示正常数据。
