+实际上本次测评的虽然是SDIO，但是在官方资源描述是SDHC，在网上简单找了下资料： + +| SD卡（Secure Digital Memory Card） | Mini SD卡（Mini Secure Digital Memory Card） | SDHC卡（Secure Digital High Capacity） | SDXC卡(SD eXtended Capacity) | +| ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ | +| SD是早先的版本的，据说是由MMC演变而来的。最大支持2GB大小容量。通过9针的接口界面与专门的驱动器相连接，SD接口除了保留MMC的7针外，还在两边加多了2针，作为数据线。SD卡的通信协议包括SD总线和SPI两类，通信电压范围：2.0-3.6V；工作电压范围:2.0-3.6V。SD卡的结构能保证数字文件传送的安全性，也很容易重新格式化，所以有着广泛的应用领域。 | miniSD卡是SD卡发展而来，性能和传统的SD卡并无大的区别，T-Flash卡：全名（TransFLash由），是一种超小型卡（11151MM）。TF卡可经SD卡转换器后，当SD卡使用。 | SDHC是大容量SD卡，也就是SD High Capacity，支持最大32GB大小容量。SDHC，Secure Digital High Capacity，大容量SD，也就是说，超过2G的SD都叫SDHC，因为早期的SD使用的是FAT16文件系统，并不支持大容量，而SDHC升级为FAT32，才支持2G以上的大容量。 | SDXC除了容量可以升级为最大2T以外，主要是可以支持300M/s的传输速度，也就是说是“高速SD”卡。SDXC又是不可向下兼容的，不支持普通的SD和SDHC卡槽和读卡器。 | + +### 2.2 新建工程 +

+SDIO 外设驱动 + +![SDIO driver.PNG](Book_Picture/f1bbc1ab31c05d9a0d06a79c2b104285.png) + +结束后退出并保存，注意这里要重新生成以下keil工程，否则keil里是没有刚刚新的配置的。 + + + +### 2.4 代码验证 + +使用Keil编译并下载Demo程序 + +#### 2.4.1 SD卡识别 + +```c +#ifdef RT_USING_SDIO + rt_thread_mdelay(2000); + if (dfs_mount("sd", "/", "elm", 0, NULL) == 0) + { + rt_kprintf("sd mounted to /\n"); + } + else + { + rt_kprintf("sd mount to / failed\n"); + } +#endif +``` + +![sd mount.PNG](Book_Picture/6d07ca7e31b3d94cfb432a9e0bcb002f.png) + + + +#### 2.4.2 文件读写测试 + +##### 2.4.2.1 代码实现 + +写一个文件读写的测试case，主要实现的功能有： + +1. 在当前目录打开或新建一个名为“test.txt”的文件 +2. 在文件中写入一段文字，关闭文件 +3. 重新打开文件，并读取打印其中的文字 + +代码实现如下： + +```c +#include +#include "drv_pin.h" +#include "dfs_fs.h" +int rwTest(void) +{ + FILE *fout; + char buf[32]; + const char test[] = "This is a test file"; + rt_kprintf("This is SD card read&write test\r\n"); + fout = fopen("test.txt", "wb"); + if (fout == NULL) { + printf("Failed to open file \"%s\"\n", "test.txt"); + exit(-1); + } + fwrite(test,

+ rt_kprintf("Read from file: %s \r\n", buf); +} +MSH_CMD_EXPORT(rwTest, rwTest); +``` + +##### 2.4.2.2 测试结果 + +![rw.PNG](Book_Picture/16faf008b7fe429125be96393f0a3e53.png) + + + +使用ls命令查看文件，并使用cat命令查看文件内容： + +![cat.PNG](Book_Picture/ad54cc1ea50b101a627e2f282851b181.png) + + + +#### 2.4.3 读写速度测试 + +##### 2.4.3.1 代码实现 + +对于读写速度测试，由于自己对RTOS的领悟还没有那么深刻，设计的方案可能不那么科学，如果有上面欠考虑的地方还请多多指教。 +按照自己的理解设计了一个测试case，主体思路就是对512B - 64KB的读写速度进行测试，使用timer0记录时间。 + 代码如下： + +```c +#include +#include "drv_pin.h" +#include "dfs_fs.h" +void readWriteTest(int size) +{ + FILE *fout, *fin; + void* buf; + rt_device_t hw_dev; + rt_hwtimerval_t timeout_s; /* 用于保存定时器经过时间 */ + /* 查找定时器设备 */ + hw_dev = rt_device_find("timer0"); + rt_device_open(hw_dev, RT_DEVICE_OFLAG_RDWR); + /* 设置定时器超时值为10s并启动定时器 */ + timeout_s.sec = 10; /* 秒 */ + timeout_s.usec = 0; /* 微秒 */ + fout = fopen("test.txt", "wb"); + buf = malloc(size); + rt_memset(buf, 0xff, size); + if (fout == NULL) { + printf("Failed to open file \"%s\"\n", "test.txt"); + exit(-1); + } + if (rt_device_write(hw_dev, 0, &timeout_s, sizeof(timeout_s)) != sizeof(timeout_s)) + { + rt_kprintf("set timeout value failed\n"); + return; + } + fwrite(buf, 1, size, fout); + fclose(fout); + rt_device_read(hw_dev, 0, &timeout_s, sizeof(timeout_s)); + rt_kprintf("%d Byte write test, time cost: Sec = %d, Usec = %d\n", size, timeout_s.sec,timeout_s.usec); + fin = fopen("test.txt", "r"); + if (rt_device_write(hw_dev, 0, &timeout_s, sizeof(timeout_s)) != sizeof(timeout_s)) + { + rt_kprintf("set timeout value failed\n"); + return; + } + fread(buf, 1, size, fin); + fclose(fin); + rt_device_read(hw_dev, 0, &timeout_s, sizeof(timeout_s)); + rt_kprintf("%d Byte read test, time cost: Sec = %d, Usec = %d\n", size, timeout_s.sec,timeout_s.usec); + free(buf); +} +int speedTest(void) +{ + rt_kprintf("This is SD card speed test\r\n"); + readWriteTest(512); + readWriteTest(1024); + readWriteTest(2048); + readWriteTest(4096); + readWriteTest(8192); + readWriteTest(16384); + readWriteTest(32768); + readWriteTest(65536); +} +MSH_CMD_EXPORT(speedTest, speedTest); +``` + + + +##### 2.4.3.2 测试结果 + +结果说实话还是很出乎我的意料的，自己也做了反复尝试 + +![sp.PNG](Book_Picture/05c353a5faaf96a8c59f5377dc88f3ef.png) + +初步的结论是，4K以下的读写速率相差很小，可能是主要的时间消耗在了调用和系统调度。之前在另一块产品中，主频比这个单片机低很多，而且还是使用的SPI接口，但是写一个512的扇区也只需要6ms，而这里竟然需要15ms。好在随着我不断加大测试数据量，区别在大数据读写还是很大的。 + + + +### 2.5 一些思考 + +我觉得这个测试仍然存在一些疑点，目前我怀疑的有以下几个，如果有知道的大佬欢迎讨论，或者不知道我们一起学习也可以。 + +1. 4K以下读写或许和文件系统实现有一些关系 +2. 也可能和SDIO的实现有关系 +3. 或许我采用的计时方式并不准确，有一个很大的基准值叠加在了结果上面，导致实际观测的实际差不准确 +4. 其他的，欢迎大家补充讨论。 + + + +### 2.6 开发资料 +

工具对项目进行配置，实现WiFi网络延迟和带宽测试。 + +> ENV环境 + +## 2. 步骤说明 + +### 2.1 RW007模组介绍 + +RW007模组是由上海睿赛德电子科技有限公司开发的一款支持WiFi和蓝牙功能的无线通信模块，它提供了基于SPI和UART 两种接口的通信方式。 + +RW007模组硬件资料： https://pan.baidu.com/s/1NeQN2XNIUv4JP2ina4pnMw + +SPI接口相对于UART接口，具有更高的通信速率，因此本文采用SPI接口进行实验。 + +RW007模组工作在SPI模式下时，主控芯片为模组需要提供1组SPI信号，一个中断输入，一个IO输出，包含电源和地总，一共8个引脚。 + +RT-Thread官方也提供了RW007模组的Arduino评估板（以下简称RW007评估板），如下图所示： + +![image7.jpg](Book_Picture/b3482634df549c911fcec6023824d8a5.jpg.webp) + +图片中间部分为RW007模组。 + +查阅RW007评估版原理图，可以看到SPI和UART接口部分，如下图所示： + +![image8.png](Book_Picture/3dc411c95c06ed52e23c0305771a79d6.png) + +可以看到，Arduino接口与RW007模组引脚的连接关系，如下表所示： + +| Arduino接口引脚 | 模组引脚 | 功能说明 | +| --------------- | -------- | ------------------- | +| D13

rw007软件包实现了MCU主控端与RW007模组的SPI/UART接口的底层通讯，同时实现了与RT-Thread的WiFi框架、网络协议栈对接。借助此软件包，开发者可以在RT-Thread系统上轻松实现WiFi联网或BLE功能。 + +软件包源码仓库链接： https://github.com/RT-Thread-packages/rw007 + +软件包源码仓库链接（国内镜像）： https://gitee.com/RT-Thread-Mirror/rw007 + +### 2.4 RT-Thread env工具简介 + +RT-Thread Env 工具 包括配置器和包管理器，用来对内核和组件的功能进行配置，对组件进行自由裁剪，对线上软件包进行管理，使得系统以搭积木的方式进行构建，简单方便。 + +RT-Thread Env工具下载页面： https://www.rt-thread.org/download.html#download-rt-thread-env-tool + +### 2.5 新建工程 + +首先，克隆RT-Thread主线源码到本地（Windows系统使用git-bash）： + +```c +$ mkdir -pv /e/Opensource/rt-thread/master +$ cd /e/Opensource/rt-thread/master +$ git clone https://github.com/RT-Thread/rt-thread.git . +``` + +接着，跳转到 FRDM-MXCN947 板级支持包（BSP）目录： + +```c +$ cd bsp/nxp/mcx/mcxn/frdm-mcxn947/ +``` + +最后，使用 scons 命令创建独立的项目目录（可以在env命令行，或者gitb-bash中执行）： + +```c +scons --dist --target=mdk --project-name=rtt_n947 --project-path=e:/DIY/FRDM-MCXN947/rtt_n947/ +``` + +其中，target参数用于指定项目模板（可以使用mdk、iar等），project-name参数和project-path参数分别表示项目名称和项目目录，可以根据实际需要修改修改。 + +注意：git-bash执行scons之前，需要保证已经安装了Python，并且已使用pip install scons安装scons软件包。否则会报 scons 命令找不到。 + +scons命令执行成功，命令输出，如下图所示： + +![Untitled.png](Book_Picture/80d2efed3f88aa75fd44818988e42b46.png) + +scons命令创建的目录，内容如下图所示： + +![Untitled 1.png](Book_Picture/3d41a9fa3c57448ade0a0aa5d77c5d11.png.webp) + +其中，rtt_n947开头的两个文件，就是scons生成的项目文件。如果不加—project-name参数，则是project开头的两个文件。 + +#### 2.5.1 添加rw007软件包 + +在env命令行环境中，跳转到上一小节创建的项目目录 E:\DIY\FRDM-MCXN947\rtt_n947目录， + +然后，使用 menuconfig 命令： + +![Untitled

+保存配置后，就可以退出配置界面了。 + +#### 2.5.3 启用pin驱动 + +类似的，依次进入菜单： + +→ Hardware Drivers Config → On-chip Peripheral Drivers + +如下图所示： + +![Untitled 4.png](Book_Picture/6c71b7d9c0c8f9872455f4ab9e40fd05.png.webp) + +如图，选中Enable GPIO。 + +这样，就开启了pin驱动。开启pin驱动的原因是，SPI的CS使用了pin接口进行控制。 + +左右移动光标到Save上，回车保存配置。 + +保存配置之后，.config和rtconfig.h文件将会更新。 + +保存配置后，就可以退出配置界面了。 + +##### 2.5.4 禁用rw007的STM32驱动 + +类似的，依次选择： + +RT-Thread online packages → IoT - internet of things → Wi-Fi → rw007: SPI WIFI rw007 driver + +进入rw007软件包配置界面： + +![Untitled 5.png](Book_Picture/ac0cc0a33054c1f42ea7793983363a76.png.webp) + +上下移动光标到”example driver port (rw007 for stm32)”上，回车，进入这个配置项： + +![Untitled 6.png](Book_Picture/422e413c17e49c594384849f320fa19c.png) + +选中，not use example driver porting by myself。 + +选中之后，自动返回rw007软件包配置页面： + +![Untitled 7.png](Book_Picture/114cc98c7d9ffe68287d0a05f10aa4c3.png.webp) + +此时，rw007的STM32驱动就被禁用掉了。 + +左右移动光标到Save上，回车保存配置。 + +保存配置之后，.config和rtconfig.h文件将会更新。 + +保存配置后，就可以退出配置界面了。 + +#### 2.5.5 下载软件包 + +刚刚我们用menuconfig选中了“RT-Thread online packages”中的rw007软件包，rw007软件包的代码默认不在本地。menuconfig选中并保存配置后，需要运行pkgs —update命令，才能将rw007软件包的代码下载到本地。 + +执行pkgs —update命令，输出如下图所示： + +![Untitled 8.png](Book_Picture/5b30c90856e2424e76530f657e8018f3.png) + + + +#### 2.5.6 更新MDK项目文件 + +使用menuconfig命令修改配置之后（尤其是增加软件包之后），需要更新MDK项目文件，新增的代码才会被编译。 + +对于scons创建时添加了project-name参数的，更新时也要加project-name参数： + +![Untitled 9.png](Book_Picture/22790b72439b99e5c9ddbe898be7f5fc.png) + + + +### 2.6 编译运行 + +#### 2.6.1 打开MDK项目 +

+执行pkgs —update命令，输出如下图所示： + +![Untitled 22.png](Book_Picture/e9d38f294eb0593793e8adb8e1b09a5d.png) + +更新MDK项目文件： + +![Untitled 23.png](Book_Picture/b6fccdaf6a77aca1c240dd2d97d04fa9.png) + +重新编译固件，下载固件，复位运行，串口终端就有iperf命令了： + +![Untitled 24.png](Book_Picture/2c4767ecb1f1b15782557e4b0d65fc78.png) + + + +#### 2.9.2 iperf命令参数 + +直接运行iperf，默认输出帮助信息： + +![Untitled 25.png](Book_Picture/86b60df9aea75b4078160feb2b0b10e6.png) + +可以看到iperf的命令参数使用方法。 + +注意： + +1. RT-Thread的iperf命令实现中，对参数的顺序由要求，如果使用过程中发现参数报错，需要查看源码定位原因； +2. RT-Thread的iperf不支持持续时间选项，一般是先启动，后通过stop选项停止的方式控制测试时长； + +#### 2.9.3 PC端的iperf + +PC端的iperf可以到iperf项目官网下载：https://iperf.fr/iperf-download.php + +我使用的mobaxterm，里面自带了iperf命令，所以就不单独下载了： + +![Untitled 26.png](Book_Picture/d2153619c42fa7a91b7333b639a1c4f6.png) + +#### 2.9.4 iperf测试准备工作 + +进行iperf测试之前，需要准备： + +1. 最好用PC创建热点，用无线路由器也行，但是需要确保信号强度足够； +2. 确保开发板和PC直接的距离不要太远，否则WiFi信号较弱，测试的结果可能会偏小； +3. 最好在WiFi热点较少的环境下进行测试，否则测出的结果数据也会偏小； + +#### 2.9.5 进行iperf带宽测试 + +下面进行测试，测试步骤如下： + +1. 在PC上，启动iperf服务端：iperf -s -p 5678 + +2. 在开发板上，通过ping命令测试开发板和PC直接IP是否可达 + +3. 在开发板上，启动iperf客户端：iperf -c 192.168.3.6 -p 5678 （其中192.168.3.6是PC的IP地址） + + 启动后，可以通过ps命令查看正在运行的线程 + +4. 一段时间后，在开发板上，停止iperf客户端：iperf —stop + +5. 开发板上iperf停止后，PC端应该可以看到iperf的输出； + +开发板上整个过程的输出如下： + +![Untitled 27.png](Book_Picture/7917ecb6def15896c8ce88f7c4b1aad2.png) + +PC端输出： + +![Untitled 28.png](Book_Picture/3511bc7aae896250e2880914fdfef384.png) + +可以看到带宽为7.02Mbps。 + + + +#### 2.9.6 iperf测试小结 + +实际上，影响WiFi带宽测试结果数据的因素很多。我们这里，其中，起决定性的的主要由以下几个方面： + +1. 模组本身支持的最高WiFi传输速率； +2. 模组接口支持的最高工作频率； +3. 主控芯片接口最高支持的工作频率； +4. 热点的WiFi最高传输速率； +5. 各种环境因素，例如开发板和PC直接的距离、环境是否有其他热点干扰等等； + +为了测出比较高的数据，我把开发板直接放到路由器天线边上，才测到以上的结果： + +![mcxn947_wifi_ap.jpg](Book_Picture/349ddb16fe5330db0777ff5ae019925b.jpg.webp) + +### 2.10 补充说明 + +如果有时候测试发现栈溢出，则需要修改TCPIP线程栈大小： + +![Untitled 29.png](Book_Picture/8bfdc1c411e8b2fe2c1e8569ef6fbfd0.png) + +将其修改为4096即可。 + + + +## 3. 原文连接 + +原文连接：https://club.rt-thread.org/ask/article/d3a1d5b19289eba5.html + + + +# **十七、恩智浦FRDM-MCX947上的WDT看门狗实践**（何剑波） + +## 1. 开发环境 + +> ENV环境 + +## 2. 步骤说明 + +### 2.1 看门狗学习 + +#### 2.1.1 寄存器介绍 + +- Mode(MOD) + - bit6 DEBUG_EN + - 只能在芯片处于debug模式的时候才能用 + - bit5 Lock + - 目的是保护看门狗振荡器不被改变 + - bit4 + - 喂狗方式 + - 0的时候 可以随时改变TC值 + - 1的时候 只能 TV 小于 WARNINT 或者 WINDOW的时候才能改变 TC值 + - bit3 + - Warning中断标志位 + - bit2 + - 超时标志位 + - bit1 + - 超时是否复位芯片 + - bit0 + - 使能看门狗 +- Timer Constant(TC) + - 定时器数值 +- Feed Sequence(FEED) + - 先后写入 AAh和 55h后，会重新加载TC值 +- Timer Value(TV) + - 看门狗计数器 +- Warning Interrupt Compare Value(WARNINT) + - 产生中断的值 +- Window Compare Value(WINDOW) + - 复位看门狗的值 + +**注意事项**： + +A feed is correct when both of the following conditions are true: + +- A valid feed sequence completes, writing AAh followed by 55h to FEED[FEED]. +- The value of TV[COUNT] is not greater than the value of WINDOW[WINDOW]. + +### 2.2 代码实现 + +逻辑图 + +![逻辑图.jpg](Book_Picture/7fc5d935c21266dbbedf332713faa96b.jpg.webp) + +现象截图 + +![串口log.jpg](Book_Picture/060934c3053b7cd81675d46db692d0fa.jpg) + + + +### 2.3 开发资料 + +代码：https://gitee.com/he_jianbo/rttfor-mcxn947.git + +工程demo：https://github.com/RT-Thread/rt-thread.git + +RT-Thead手册：https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/programming-manual/basic/basic?id=rt-thread-%e5%90%af%e5%8a%a8%e6%b5%81%e7%a8%8b + +NXP论坛：https://www.nxpic.org.cn/module/forum/forum-1326-1.html + +RTT论坛：https://club.rt-thread.org/index.html + + + +## 3. 原文连接 + +原文连接：https://club.rt-thread.org/ask/article/b20d16bdccbd173e.html + diff --git a/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxn947/quick-start.md b/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxn947/quick-start.md index 8797e77ea71bb2240908955767622337915500d7..5078341978e57e61bd1e5ca302c24a64a6fcea8f 100644 --- a/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxn947/quick-start.md +++ b/rt-thread-version/rt-thread-standard/tutorial/quick-start/frdm_mcxn947/quick-start.md @@ -73,3 +73,7 @@ msh > ## 继续学习 已完成 RT-Thread 快速上手！点击这里进行 [内核学习](../../kernel/kernel-video.md) 。 + +## 其他资料 + +[恩智浦FRDM-MCXN947开发实践指南](/rt-thread-version/rt-thread-standard/tutorial/make-bsp/NXP-MCX/恩智浦FRDM-MCX974实践指南.md)
