回复: 整了个D1s的小板子跑毕设发布在 D1系列-RISC-V
更新一下水个贴。
第一版各种问题还是挺多的，比如sd卡座封装画反了，画原理图脑抽把一个ddr供电口的网络标签搞成了文本
，layout的时候也没注意，导致ddr没供电，只能跳线。。。。。
不过最后还是把系统启动了，皆大欢喜。放点图：

下载一下相应的编译器并解压：
gcc-arm-none-eabi-8-2019-q3-update-linux.tar.bz2tar -jxvf gcc-arm-none-eabi-8-2019-q3-update-linux.tar.bz2然后修改gcc.mk中指向的目录即可，如下：
CC_DIR := ~/gcc-arm-none-eabi-8-2019-q3-update/bin后面详细列出了make方式，注意要在SDK最顶层下执行。
3、编译DEMO
首先需要执行一下：
make menuconfig然后保存退出即可。
然后执行：
make PRJ=demo/hello_demo可以看到结果：
text data bss dec hex filename 39752 1576 2248 43576 aa38 hello_demo.elf make[2]: Leaving directory `/home/allwinner/xr806_sdk/project/demo/hello_demo/gcc' make[1]: Leaving directory `/home/allwinner/xr806_sdk/project/demo/hello_demo/gcc' /home/allwinner/xr806_sdk4、制作镜像
进入上一步的demo目录下：
cd project/demo/hello_demo/gcc/执行
make image可以看到：
Flash Layout: sec bin 0 boot_40M.bin : flash_offs: 0x00000000( 0K) data_size: 0x00002F28( 12K) sec bin 1 app.bin : flash_offs: 0x00004000( 16K) data_size: 0x00004920( 19K) sec bin 2 app_xip.bin : flash_offs: 0x00029800( 166K) data_size: 0x000058D0( 23K) generate image: xr_system.img cp -t ../../../../out/ ../image/"xr806"/*.bin ../image/"xr806"/xr_system.img *.map回到SDK根目录下可以看到out文件夹，进入后可见输出文件：
allwinner@allwinner-VirtualBox:~/xr806_sdk/out$ ls app.bin app_xip.bin boot_40M.bin hello_demo.map sys_sdd_40M.bin wlan_bl.bin wlan_fw.bin xr_system.img5、烧录
在SDK的tools文件夹下可见有烧录工具：
allwinner@allwinner-VirtualBox:~/xr806_sdk/tools$ ls Blink.apk fs_img_tools mkimage.exe phoenixMC.dll settings.ini SoundConfig.apk config HcidumpXr.7z mkimage_mac64 phoenixMC.exe settings_mac.ini efuse_tool map_parse_gcc_v3.py phoenixMC phoenixMC_mac64 signpack.sh etfGuiTool.exe mkimage phoenixMC_cli.exe sdd_editor SmartConfig.apk由于想偷懒，没在虚拟机下烧录，直接把img和工具都拖到Windows下：
完成烧录：

回复: 【DIY教程】XR806雪花灯发布在 XR系列-无线互联
鸽了好久，今天正式开始更新教程。
虽然只是为了做一个雪花灯，但要考虑的因素还是很多的。
-
大小要刚好，直径为10cm以内的话差不多能刚好拿在手里，所以要稍微考虑用料尺寸。
-
色调要丰富，一个个led去布板子肯定是不理想的，且XR806板载引出IO不算特别多，想要达到可编程控制的花式效果最好还是采用WS2812这种多色的可以用pwm信号控制的灯珠。
-
摆脱电源线，由独立的电池供电，可充电，能给开发板和led同时供电是最理想的。
开发工具首选LCEDA，比较简单友好。先从原理图开始，XR806的开发板作为核心板肯定是不会再改动了，刚好有用户在元件库上传了一个XR806的原理图，一搜就有，检查了一下原理图引脚都是正确的，就直（lan）接（gou）拿来用好了
，不过封装库有点问题，layout的时候再改改就是了。
由于核心板已经相当于一个最小系统，就省下了一大堆启动电路什么的，调试的话肯定也是用板载的typec接口。但总得有个给电池充电的接口，这是免不了的。为了简单、方便我这种手残党焊接，我还是决定选择microUSB的端口作为充电接口：
只需要正负极引入即可，封装的话可以随便挑选一些有过孔的，方便焊接就行。接下来最麻烦的地方来了：充电电源管理方案。
先看看选什么电池，虽然某宝上的很多锂电池包都声称带了防过充ic，但相信玩多了的话自然也没少炸过。追求安全的话还是得铅酸电池。but找了一圈貌似没有体积小且有5v输出的。所以还是随便找了一个带保护的锂电池，选价格稍微高一点的希望有点保障。
从电路功能上去看，就得回归到最开始，从我的目的出发：能给XR806雪花灯板子上的电池充电，并且电池可以给806和LED供电。自己从头搭这么一个功能电路对于我这样的手残党肯定是不太可能的，费事费力且失败率高，且搭出来也不符合我对体积的要求。所以我首先考虑的是就是集成方案了。
最常见的就是某4056/4057方案，后者体积小一点带防反接，除此之外没啥区别，可以看看datasheet中的相关描述：4056 是一款完整的单节锂离子电池采用恒定电流/恒定电压线性充电器。其底部 带有散热片的 SOP8/MSOP8 封装与较少的外部元件数目使得 TP4056 成为便携式应用的 理想选择。TP4056 可以适合 USB 电源和适配器电源工作。由于采用了内部 PMOSFET 架构，加上防倒充电路，所以不需要外部隔离二极管。 热反馈可对充电电流进行自动调节，以便在大功率操作或高环境温度条件下对芯片温度 加以限制。充电电压固定于 4.2V，而充电电流可通过一个电阻器进行外部设置。当充电 电流在达到最终浮充电压之后降至设定值 1/10 时，TP4056 将自动终止充电循环。 当输入电压（交流适配器或 USB 电源）被拿掉时，TP4056 自动进入一个低电流状 态，将电池漏电流降至 2uA 以下。TP4056 在有电源时也可置于停机模式，以而将供电 电流降至 55uA。TP4056 的其他特点包括电池温度检测、欠压闭锁、自动再充电和两个 用于指示充电、结束的 LED 状态引脚。如此一来要满足我们充电的需求是绰绰有余了，but还有一点非常重要，就是我们还需要给led供电和806供电，如果让电池直接供电，很明显还是要有一个稳压，这个时候怎么办呢？再加一个LDO？
当然这种麻烦的地方很多厂商肯定也想到过了，所以最后我找到了5400这个方案。看看他的相关描述：
5400是一款移动电源专用的单节锂离子电池充电器和恒定5V升压控制器，充电部分集高精度电压和充电电流调节器、预充、充电状态指示和充电截止等功能于一体，可以输出最大1A充电电流。而升压电路采用CMOS工艺制造的空载电流极低的VFM开关型DC/DC升压转换器。其具有极低的空载功耗（小于10uA），且升压输出驱动电流能力能达到1A。无需外部按键，可以即插即用。 充电部分为线性降压方式，内置PMOSFET，加上防倒灌电路，所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节，以便在大功率操作或高环境温度条件下对芯片温度加以限制，充满电压固定于4.2V。充电电流可通过一个电阻器进行外部设置。当电池达到4.2V之后，充电电流逐渐下降至设定电流值1/5，TP5400将自动终止充电。升压部分同样内置了功率NMOSFET，较小的内阻可以提供驱动能力达到5V/1A。较高的集成度使得TP5400只需少量的外围器件即可正常工作。TP5400还集成了充电温度保护，升压输入电源限流环路，可根据负载情况动态调节电流，并具有快速响应和过流关断功能。升压转换器采用变频的方式，因此较国内外同类产品具有极低的空载功耗、纹波、更强的驱动能力，以及更高的效率。又能充电，又能稳压供电，符合需求！封装也不大，8pin的ESOP。还要什么自行车呢
。官方文档里也贴上了典型应用电路：
我一看，这不是基本上是完活了嘛，直接抄起来就完事
。十分容易就从LC的元件库里搜到了器件，照葫芦画瓢搭建就完事了：
具体的功能原理的话自行查阅datasheet。虽然这么随便不知道会不会有瑕疵，但还是保守起见，在电池接口处加一个双排拨码开关，可以保证功能部分和充电部分各自独立。
最后就是WS2812灯珠了，这个简单，一个个接上正负极后首位相连即可。
由于我规划的雪花有6个花瓣，所以我这边就先打算分别选806上6个有pwm功能的io，每个io分别控制5个LED。
如果后续功能有异常也无所谓，大不了我们就采用精准延时的方法去挨个管脚点灯就是了。
把端口连接上开发板：
好了原理图到这里就基本结束了，贴个源文件Schematic_XR806雪花灯_2022-03-08.pdf ，接下来就是PCB部分！

make menuconfig可以看到图形化配置界面：
勾选上ble的全部内容即可：
同时也要在
\device\xradio\xr806\BUILD.gn路径下启用console命令行：
后烧录即可。（不用勾选编译鸿蒙系统也可以，此为原生接口测试用例）
可见log如下：
初始化命令：
ble init可见：
若系统启动后没有进行 BLE 初始化，执行其他 BLE 命令前都需要先执行该初始化命令。
反初始化命令：
ble deinit查看所有指令：
ble help显示BLE设备名称：
ble name创建BLE地址：
ble id-create xx:xx:xx:xx:xx:xx视系统设置允许创建多少个 BLE 私有地址，当前最多只允许 1 个私有地址存在，地址默认 为 random 类型，当前基本不使用。可在 ble init 之前调用，但不会存储到 flash 之中。
显示BLE地址：
显示当前私有地址信息。
ble id-show
选择BLE地址当前选择使用的BLE 地址.
ble id-select 0BLE扫描:
BLE 开启扫描：ble scan on BLE 停止扫描：ble scan off删除BLE地址：
ble id-delete <id>默认只有 1 个 BLE 私有地址，所以无法删除，当前无法正常使用。
后面会持续更新蓝牙广播等操作。

【跑个算法】之模拟退火算法在D1的执行发布在 D1系列-RISC-V
前言：之前有做过一个VLSI布局布线相关的课题，学了一点关于模拟退火算法的毛皮，今天来跑个demo复（shui）习（tie）一下
。Simulated annealing这种算法的出发点是基于物理中固体物质的退火过程与一般组合优化问题之间的相似性。模拟退火算法是一种通用的优化算法，其物理退火过程由以下三部分组成：
（1）加温过程
（2）等温过程
（3）冷却过程
其中加温过程对应算法设定的初始温度，等温过程对应算法的Metropolis（一种采样算法）抽样过程，冷却过程对应控制参数的下降。这里能量的变化就是目标函数，要得到的最优解就是能量最低状态。Metropolis准则是SA算法收敛于全局最优解的关键所在，Metropolis准则以一定的概率接受恶化解。
总的来说就一句话：相比于类似爬山算法这种贪心算法，SA可以跳出局部最优解。
理解的大概原理后，就来看看代码。

由于使用的是H3，就直接用GCC编译即可生成执行文件。
发现屏幕没有中字模哈哈，串口运行看看：pi@Quark-N:~/WorkSpace/SA_Algorithm$ ./test 采用模拟退火算法，初始温度T0=50000.00,降温系数q=0.98,每个温度迭代1000次,共降温1448次，得到的TSP最优路径为: 27--->30--->31--->1--->15--->14--->13--->12--->29--->11--->23--->5--->6--->7--->10--->9--->8--->2--->4--->16--->19--->17--->3--->18--->22--->21--->20--->24--->25--->26--->28 最优路径长度为:15683.072504 程序运行耗时:39.690700秒. pi@Quark-N:~/WorkSpace/SA_Algorithm$ ./test 采用模拟退火算法，初始温度T0=50000.00,降温系数q=0.98,每个温度迭代1000次,共降温1448次，得到的TSP最优路径为: 27--->31--->30--->25--->20--->24--->23--->5--->6--->11--->29--->1--->15--->14--->12--->13--->7--->10--->9--->8--->2--->4--->16--->19--->17--->3--->18--->22--->21--->26--->28 最优路径长度为:16072.436112 程序运行耗时:39.947321秒. pi@Quark-N:~/WorkSpace/SA_Algorithm$ ./test 采用模拟退火算法，初始温度T0=50000.00,降温系数q=0.98,每个温度迭代1000次,共降温1448次，得到的TSP最优路径为: 19--->16--->4--->8--->9--->10--->2--->7--->6--->5--->23--->24--->20--->25--->29--->11--->13--->12--->14--->15--->1--->31--->30--->27--->28--->26--->21--->22--->18--->3--->17 最优路径长度为:15996.839897 程序运行耗时:39.952181秒.将近40秒。而且不出所料，执行完后非常烫手（毕竟板子尺寸摆在那里）。前两者相比起来就较为风轻云淡。当然了这之间其实也没什么可比性，毕竟夸克还同时点着个屏幕，玩起来纯属娱乐哈哈，如果有大佬有兴趣也可以尝试优化一下，我还是希望起个抛砖引玉的作用
。至于每次的结果为什么都不一样，简单按网上内容解释一下：SA算法本身是一种随机算法，转移向更差的解不是必然，而是概率性的，也就是说每次执行算法时，执行过程转移到的解可能都是完全不一样的。至于旅行商（Traveling Salesman Problem, TSP） 问题，本身属于NP-hard问题，找不到存在多项式时间复杂度的解。
如果要求精确的解，目前可行的方法有枚举、分支限界、动态规划等，但这些方法适用的数据范围都很小，一旦数据规模变大，它们都将无能为力。所以目前广泛使用的大都是一些随机算法，比如蚁群、遗传等，模拟退火就是其中的一种，这些算法的一大特点就是通过随机去逼近最优解，但也有可能得到错解。

ok，今天的帖就水到这里。

回复: 【XR806开发板试用】棋子分拣机发布在 XR系列-无线互联
技术原理
关于技术实现，用到的材料主要有XR806开发板、两个9g的舵机，以及一个红外光传感器。
工作机制非常简单，如图所示：
上电后舵机复位到初始状态，任何开始工作，由一号舵机把待分类的棋子推移到检测区域，由红外传感器判断棋子的颜色，白色返回值为1，黑色则为0。
硬件模型制作
这一部分看似工作量大，但其实是参考了网上一些开源的例程，只不过加以了尺寸改动。
实现方法可以用3d打印或者激光切割亚克力，我选择了后者因为时间相对简短。使用的建模软件为Solidworks2019，亚克力板厚度后3mm，画好零件后，搭建好装配体确认尺寸无误后转为dxf格式即可用CNC机床切割。（我是用了学校的CNC，网上切也很便宜哈）
电路部分
使用的开发板为XR806，一款iot产品开发板，他最大的特点就是适配的轻鸿蒙，使用起来能有不错的体验。
需要驱动的设备就是两个舵机及一个红外传感器。
舵机就是一种位置伺服的驱动器，适用于那些需要角度不断变化并可以保持的控制系统。其工作原理是：控制信号由接收机的通道进入信号调制芯片，获得直流偏置电压。它内部有一个基准电路，产生周期为20ms，宽度为1.5ms的基准信号，将获得的直流偏置电压与电位器的电压比较，获得电压差输出。最后，电压差的正负输出到电机驱动芯片决定电机的正反转。当电机转速一定时，通过级联减速齿轮带动电位器旋转，使得电压差为0，电机停止转动。
以180度角度伺服为例，那么对应的控制关系是这样的：
0.5ms--------------0度；
1.0ms------------45度；
1.5ms------------90度；
2.0ms-----------135度；
2.5ms-----------180度；
拆开看看：
减速齿轮
驱动电路
因为片子上的字眼实在太小，令人“望眼欲穿”，本来还想查查有没有技术文档研究一下，只能放弃先了。刚好鸿蒙也适配了pwm的接口驱动xr806，所以我们只要修改freq频率和duty占空比两个选项如下即可。
IoTPwmStart(PWM_OUTPUT_CH0,8,50);关于其他基础操作姿势可以参考我之前的一篇呼吸灯的demo帖子。还有一点值得一提的是关于这种舵机的输入信号口我是用806上的接口直接驱动的，并没有再拉高，内部是否需要或者有没有额外的驱动由于没有舵机内部电路的原理图也暂时无从得知，但总感觉在调节duty占空这一参数时舵机时而会不听使唤（占空比调制不准确），希望有大佬指点。
红外传感器原理则相对简单，一个红外发射管和一个红外接收管。模块通电后红外发射管向前方不断发射一定频率的红外线，
通过板载了一个电压比较器LM393
比较输出和输入的信号做出相应反馈，体现到我手里这块小板子上就是接收到红外信号为1，没有接收到（遇到黑色物体）则为0。所以读取判断值的代码相对简单：
IoTGpioGetInputVal(13,&mode);整体代码部分
openHarmony用的是gn和ninja编译，由很多种上手学习方式，如果说gn对标的是gcc脚本构建生成器，ninja就对应的是makefile构建系统文档了。

"GO_sorting:app_GO"总结
到此基本功能是实现了，但有很多缺陷如我没有直观地体现出来分类后各种棋子的数量，也并没有给他加上控制开始和停止的操作。（没有一个对是否仍有棋子未被分类的判断机制）这些后续可以通过增加显示屏、替换红外传感器为压感贴片或者使用摄像头去学习判等等···最遗憾的是这个小demo暂时还没有发挥出XR806及鸿蒙的一些特征，如联网、连蓝牙。仅仅是个突发奇想的点子，希望能起到抛砖引玉的作用。后面我也会继续尝试给他加上其他功能。再贴上一些前置学习内容：

【XR806开发板试用】跑个步进电机发布在 XR系列-无线互联
从垃圾堆里翻出来个电机，今天就玩它好了，对于电机的理解已经全部还给了大学老师，所以打算先研究一番：
百度了一下，这个东西学名叫作四相五线步进电机，电机就是这个圆陀陀，板子是他的驱动器。板载芯片是ULN2003，TI出品。查了一下技术文档，就是一个集成的达令顿管放大器。
很早以前就了解过：步进电机是吃脉冲信号工作，转化信号成相应的角位移和线位移。输入一个脉冲信号，转子就转动一个角度或前进一步，其输出的角位移或线位移与输入的脉冲数成正比，转速与脉冲频率成正比。因此，步进电动机又称脉冲电动机。
步进电机相对于其它控制用途电机的最大区别是，它接收数字控制信号（电脉冲信号）并转化成与之相对应的角位移或直线位移。也就是说，它本身就可以把信号转化成运动。而且它可开环位置控制，输入一个脉冲信号就得到一个规定的位置增量，与传统的直流控制系统相比,其成本明显减低，几乎不必进行系统调整。所以他给我们带来了很大的方便。要是想要他执行起来也很简单，只要控制脉冲的数量、频率和电机绕组的相序,即可获得所需的转角、速度和方向。
从具体的硬件来看，我这里需要接六条线才能让这个电机跑起来，电源端口就不说了，IN1~IN4这四个通道口要怎么输入信号才是问题所在。
如上就是内部原理图，右侧四个开关其实就是我们的四个信号端口。右侧ABCD为定子，上面绕有线圈，为四相，与之相对应的对面四个定子上面也有线圈，相对应的两个定子之间线圈是相互连接形成一个绕组。
下面来分析一种运行模式，单四拍运行：假如说现在我闭合0对着的那个开关，则由高中学过的电能生磁原理，0对应的线圈就会产生磁力，同时他的下端，也就是对应的B线圈，也就一起导通了。接下来B断开，C导通产生磁力，1和C（这里指的是右上角那个端）就会因为两者间夹角最小而互相吸引靠近，吸引过去后C断开，D通电，继续把离他最近的2吸引过去，如此一来类推下去就形成了一个逆时针旋转的过程。
上述过程直到0被吸引到A相时，就是一个周期的完成，旋转角度为360/8=45度。
还有其他控制方法，如双拍工作、单双拍工作等等，可以根据需求调节精度速度等等···决定先放一边，适当做点容易让人有成就感的事情：用代码实现这个过程，把舵机跑起来。
了解了原理就用最简单的方法去实现好了。主要代码如下：
IoTGpioSetOutputVal(12,0); IoTGpioSetOutputVal(13,0); IoTGpioSetOutputVal(19,1); IoTGpioSetOutputVal(20,1); OS_MSleep(2); IoTGpioSetOutputVal(12,1); IoTGpioSetOutputVal(13,0); IoTGpioSetOutputVal(19,0); IoTGpioSetOutputVal(20,1); OS_MSleep(2); IoTGpioSetOutputVal(12,1); IoTGpioSetOutputVal(13,1); IoTGpioSetOutputVal(19,0); IoTGpioSetOutputVal(20,0); OS_MSleep(2); IoTGpioSetOutputVal(12,0); IoTGpioSetOutputVal(13,1); IoTGpioSetOutputVal(19,1); IoTGpioSetOutputVal(20,0); OS_MSleep(2);像前面几篇一样，烧录程序，将对应IO连接上驱动板后，通上电，电机就正常工作了。
当然光转起来有些过于简单了，所以打算加一些可控元素进去，也方便后面做各种开发。于是又从垃圾堆里翻到了这个：
用翻出来的示波器研究了一下（没有万用表555），可以理解为由上下、左右两个方向的滑动变阻器和一个按键组成，总共三个信号输出口。保持在中间位置的时候测得是2.5v，移动向两边就是0跟5v，按下就是按钮。
既然是输出模拟信号最合理就是用ADC检测，无奈鸿蒙1.x.x的版本貌似都还没适配好806的接口，hal库的代码也找不到说明文档，用hal库尝试配置了一下ADC一直没成功，只能放到后面解决了。。。
所以最终决定还是用GPIO接口去读电平高低，具体代码如下：
#Create by Randolph. import("//device/xradio/xr806/liteos_m/config.gni") static_library("app_Stepper") { configs = [] sources = ["main.c",] cflags = board_cflags include_dirs = board_include_dirs include_dirs += [ "//kernel/liteos_m/kernel/arch/include", "//base/iot_hardware/peripheral/interfaces/kits", "//device/xradio/xr806/xr_skylark/src/rom/rom_bin/src/driver", ] }main.c

至于为什么要顶个风扇叶呢，一方面是方便观察转动，另一方面也算是致敬一张大部分程序员应该都见过的图：
ok，又水了一贴，今天也是平安夜，祝各位圣诞快乐！
也挖个坑：下周会整合一下前面的内容做个小作品放出来。Merry Christmas！

【新人上手】D1哪吒开发板Tina Linux下分区烧写与分区只读发布在 D1系列-RISC-V
13、分区烧写
注意的是这一项需要用到flash.exe工具，以及一系列目标img文件。
首先进入Tina执行：
reboot bootloader进入模式后，在PC端运行platform-tools中的shell，输入：
fastboot.exe devices可见是否连接上开发板
C:\Users\xxxxxxx\Desktop\platform-tools>fastboot.exe devices Android Fastboot fastboot后可以执行相关命令如下完成烧写或擦除：
fastboot.exe flash boot boot.img fastboot.exe flash rootfs rootfs.img fastboot.exe flash u-boot image/boot_package.fex fastboot.exe erase boot fastboot.exe reboot14、分区只读
rootfs分区只读。
Tina中执行：
mount可见
/dev/root 行(一般在第一行)有ro的字样，则说明rootfs分区为可读状态，结果如下：
root@TinaLinux:/# mount /dev/root on /rom type squashfs (ro,noatime) devtmpfs on /dev type devtmpfs (rw,relatime,size=504628k,nr_inodes=126157,mode=755) proc on /proc type proc (rw,nosuid,nodev,noexec,noatime) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime) tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime) /dev/by-name/UDISK on /overlay type ubifs (rw,relatime,assert=read-only,ubi=0,vol=8) overlayfs:/overlay on / type overlay (rw,noatime,lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600,ptmxmode=000) debugfs on /sys/kernel/debug type debugfs (rw,noatime) none on /sys/kernel/config type configfs (rw,relatime) adb on /dev/usb-ffs/adb type functionfs (rw,relatime)

回复: 【XR806开发板试用】新建任务及点灯那些事发布在 XR系列-无线互联
由于手上没什么外设，决定继续从led下手。用鸿蒙的接口来实现个呼吸灯。根据OpenHarmony的要求，适配了OpenHarmony后就只有一个接口，没有原生接口了，所以之后的文档中我就不区别对待了，统一指OpenHarmony接口。
关于呼吸灯的原理，就是PWM（Pulse Width Modulation），即脉宽调制信号，应用非常广泛。最主要的特点为可以通过改变数字信号的占空比，从而达到模拟信号的效果。因此理论上只要带宽足够，任何模拟值都可以使用PWM信号进行编码。
接下来我们开始对XR806进行PWM实验：1、在Harmony\device\xradio\xr806\ohosdemo下新建任务文件夹如Breath_LED,分别添加BUILD.gn文件和main.c文件
其中BUILD.gn文件内容如下：
import("//device/xradio/xr806/liteos_m/config.gni") static_library("app_BreathLED") { configs = [] sources = ["main.c",] cflags = board_cflags include_dirs = board_include_dirs include_dirs += [ "//kernel/liteos_m/kernel/arch/include"， "//base/iot_hardware/peripheral/interfaces/kits", "//device/xradio/xr806/xr_skylark/src/rom/rom_bin/src/driver", ] }其中静态库必须以app_xxx的格式命名。
2、从代码编辑器中打开文件夹，找到device\xradio\xr806\adapter\hals\iot_hardware\wifiiot_lite 文件夹下内容，此为专门的外设接口，能看到flash、gpio、i2c、pwm等参考源文件，文件接口的头文件在base\iot_hardware\peripheral\interfaces\kits。这里我们打开iot_pwm.c文件，可以看到如下函数：
1、IoTPwmInit(unsigned int port) 2、IoTPwmDeinit(unsigned int port) 3、IoTPwmStart(unsigned int port, unsigned short duty, unsigned int freq) 4、IoTPwmStop(unsigned int port)其中 IoTPwmInit 和 IoTPwmDeinit 就是port的初始化跟去初始化，填入端口参数即可使用。IoTPwmStart 和 IoTPwmStop 就是pwm的开启与关闭。
3、接下来我们就可以开始写main.c文件的内容了。
#include <stdio.h> #include "kernel/os/os.h" #include "ohos_init.h" #include "iot_pwm.h" #define PWM_OUTPUT_CHL PWM_GROUP1_CH2 static OS_Thread_t g_main_thread; static void Breath_LED_init() { IoTPwmInit(GPIO_PORT_A);//初始化pwm端口，设置时钟信号源和分频系数等 } static void Breath_LED_start(void) { unsigned char counter = 1; for(counter = 1; counter<99; counter++) { IoTPwmStart(PWM_OUTPUT_CHL,counter,100);//升频 OS_MSleep(10); } for(counter = 99; counter >1; counter--) { IoTPwmStart(PWM_OUTPUT_CHL,counter,100);//降频 OS_MSleep(10); } } static void MainThread(void *arg) { Breath_LED_init(); while (1) { Breath_LED_start(); } } void PWM_TestMain(void)//实际入口，负责创建线程 { printf("Test Start\n"); if (OS_ThreadCreate(&g_main_thread,"MainThread",MainThread, NULL, OS_THREAD_PRIO_APP, 4096) != OS_OK) { printf("[ERR] Create PWMLED_Task Failed\n"); } } SYS_RUN(PWM_TestMain); //Harmony线程入口，在utils/native/lite/include/ohos_init.h中定义，读者可以改成其他入口类型检查差异4、配置复用端口
关于端口信息可以在PWM_CH_ID这个枚举体中查看到：
typedef enum { PWM_GROUP0_CH0 = 0U, /*!< bit 0 PORTA_PIN8 or PORTA_PIN19 */ PWM_GROUP0_CH1 = 1U, /*!< bit 1 PORTA_PIN9 or PORTA_PIN20 */ PWM_GROUP1_CH2 = 2U, /*!< bit 2 PORTA_PIN10 or PORTA_PIN21 */ PWM_GROUP1_CH3 = 3U, /*!< bit 3 PORTA_PIN11 or PORTA_PIN22 */ PWM_GROUP2_CH4 = 4U, /*!< bit 4 PORTA_PIN12 or PORTB_PIN0 */ PWM_GROUP2_CH5 = 5U, /*!< bit 5 PORTA_PIN13 or PORTB_PIN1 */ PWM_GROUP3_CH6 = 6U, /*!< bit 6 PORTA_PIN14 or PORTB_PIN2 */ PWM_GROUP3_CH7 = 7U, /*!< bit 7 PORTA_PIN15 or PORTB_PIN3 */ PWM_CH_NUM = 8U, PWM_CH_NULL = PWM_CH_NUM, } PWM_CH_ID;由于笔者的开发板上的led连接的是pin21，故在选择PWM通道时应该选择通道二，也就是PWM_GROUP_CH2, 但是值得注意的一点是有的开发板配置时考虑到IO复用问题，并没有开启相应的端口，因此需要手动配置一下。
打开
Harmony\device\xradio\xr806\xr_skylark\project\common\board\xr806_OHOS\board_config.c可以看到关于pwm的相关端口配置
__xip_rodata static const GPIO_PinMuxParam g_pinmux_pwm[] = { { GPIO_PORT_A, GPIO_PIN_19, { GPIOA_P19_F4_PWM0_ECT0, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, { GPIO_PORT_A, GPIO_PIN_20, { GPIOA_P20_F4_PWM1_ECT1, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, { GPIO_PORT_A, GPIO_PIN_22, { GPIOA_P22_F4_PWM3_ECT3, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, { GPIO_PORT_A, GPIO_PIN_12, { GPIOA_P12_F3_PWM4_ECT4, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, { GPIO_PORT_A, GPIO_PIN_13, { GPIOA_P13_F3_PWM5_ECT5, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, { GPIO_PORT_B, GPIO_PIN_3, { GPIOB_P3_F4_PWM7_ECT7, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } }, };可以看到其中是没有pin21的信息的，所以需要手动添加一句
{ GPIO_PORT_A, GPIO_PIN_21, { GPIOA_P21_F4_PWM2_ECT2, GPIO_DRIVING_LEVEL_1, GPIO_PULL_NONE } },这样就可以正常开启pwm了。
如果在其他开发中遇到调用sdk后编译正常开发板却没有响应的情况，也可以产看关于引脚复用的文档寻找问题。
5、编译烧录
最后不要忘记在/Harmony\device\xradio\xr806\ohosdemo\BUILD.gn中加入我们的任务
group("ohosdemo") { deps = [ #"iot_peripheral:app_peripheral", #"handsome_demo:app_handsome", #"wlan_demo:app_WlanTest", "Breath_LED:app_BreathLED" ] }根目录命令行执行hb build -f，然后就可以跟hello world中一样过程烧录了。
烧录后就可以看到板载呼吸灯的效果了。

【XR806开发板试用】新建任务及点灯那些事发布在 XR系列-无线互联
现在我们已经成功地完成了helloworld了，接下来就是一些个性化的开发了
首当其冲就是最基础的IO开发
下面演示如何添加自己的任务文件到系统中
1、在
Harmony\device\xradio\xr806\ohosdemo下新建文件夹，比如起名IO_TEST。
并新建main.c文件和BUILD.gn文件（建议严格按这个形式命名），后续文
件数变多的情况下也可以在任务路径下分别新建头文件和c文件的文件夹，并重新指定路径即可。
2、接下来是BUILD.gn文件（关于GN跨平台工具，想具体学习可以参考此文章https://www.cnblogs.com/bigben0123/p/12643839.html）gn文件内容如下
#Create by Randolph. import("//device/xradio/xr806/liteos_m/config.gni") static_library("app_IO") { configs = [] sources = ["main.c",] cflags = board_cflags include_dirs = board_include_dirs include_dirs += [ "//kernel/liteos_m/kernel/arch/include", ] }此处要注意的是。对static_library静态库的声明需要按照app_xxx的格式写入
3、完成了之后，c文件能自主发挥的空间就很大了。先放上代码
//Create by Randolph #include <stdio.h> #include "kernel/os/os.h" #include "ohos_init.h" #include "driver/chip/hal_gpio.h" #define GPIO_OUTPUT_PORT GPIO_PORT_A static OS_Thread_t g_main_thread; static void gpio_output_init(void) { GPIO_InitParam param; param.driving = GPIO_DRIVING_LEVEL_1; param.mode = GPIOx_Pn_F1_OUTPUT; param.pull = GPIO_PULL_NONE; HAL_GPIO_Init(GPIO_OUTPUT_PORT, GPIO_PIN_21, ¶m);//led灯对应IO } static void gpio_output_ctl(uint8_t level) { HAL_GPIO_WritePin(GPIO_OUTPUT_PORT, GPIO_PIN_21, level ? GPIO_PIN_HIGH : GPIO_PIN_LOW); } // static void gpio_output_deinit(void) // { // HAL_GPIO_DeInit(GPIO_OUTPUT_PORT, GPIO_PIN_15); // } // gpio_output_deinit();//GPIO去初始化，如果IO要去做别的事情就可以执行，我这边只点灯 static void gpio_output_test(void) { printf("gpio output test start.\n"); uint8_t i; uint8_t level = 1; for (i = 0; i < 10; i++) { gpio_output_ctl(level); printf("gpio level write %d\n", level); level = (!level & 0x01); OS_MSleep(500); } printf("gpio output test end.\n"); } static void MainThread(void *arg) { printf("Hello,XR806 This is Randolph!\n"); while (1) { gpio_output_test(); } } void IO_TestMain(void) { printf("Test Start\n"); gpio_output_init(); if (OS_ThreadCreate(&g_main_thread,"MainThread",MainThread, NULL, OS_THREAD_PRIO_APP, 4096) != OS_OK) { printf("[ERR] Create HelloWorld_Task Failed\n"); } } SYS_RUN(IO_TestMain);此处就跟玩stm32一类的主控一样了，大部分都是调用hal库，另外在
Harmony\device\xradio\xr806\xr_skylark\project\example路径内也有很多现成的例子可以参考。
当然也可以用鸿蒙的外设接口，不用原生SDK的。文件接口的头文件在：base\iot_hardware\peripheral\interfaces\kits源码在：
device\xradio\xr806\adapter\hals\iot_hardware\wifiiot_lite带有iot字样的接口就是鸿蒙的接口。
4、最后在
Harmony\device\xradio\xr806\ohosdemo\BUILD.gn路径下增加我们新建的任务文件信息如下：
"IO_TEST:app_IO"
别忘记注释掉之前的hello world！保存后，回到Harmony跟目录执行hb build -f
并在phoenixMC.exe中烧录镜像，就可以看到板子上的灯闪烁起来啦！
同时也可以从串口看到调试信息：
点灯完成！

【XR806开发板试用】从Say hello开始发布在 XR系列-无线互联
很早入了XR806，一直没整理出来点东西分享，打算开个坑，分享一些简单例程，也打算做一个完整度高的小作品，慢慢填坑哈哈。
XR806的一大亮点就是适配了鸿蒙系统，总的来说，鸿蒙系统也是有类型的，分三类
-
轻量系统（mini system）
面向MCU类处理器例如Arm Cortex-M、RISC-V 32位的设备，硬件资源极其有限，支持的设备最小内存为128KiB，可以提供多种轻量级网络协议，轻量级的图形框架，以及丰富的IOT总线读写部件等。可支撑的产品如智能家居领域的连接类模组、传感器设备、穿戴类设备等。
-
小型系统（small system）
面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为1MiB，可以提供更高的安全能力、标准的图形框架、视频编解码的多媒体能力。可支撑的产品如智能家居领域的IP Camera、电子猫眼、路由器以及智慧出行域的行车记录仪等。
-
标准系统（standard system）
面向应用处理器例如Arm Cortex-A的设备，支持的设备最小内存为128MiB，可以提供增强的交互能力、3D GPU以及硬件合成能力、更多控件以及动效更丰富的图形能力、完整的应用框架。可支撑的产品如高端的冰箱显示屏。
806用到的就应该是轻量级，而对初学者来说也有必要一提的是这个跟手机上的HarmonyOS是不一样的，可以理解为openHarmony是HarmonyOS的地基。
再者是鸿蒙系统的编译方式：gn和ninja。
如果说gn对标的是gcc脚本构建生成器，ninja（日语发音，忍者的意思，西方好像很喜欢这些东西hh）就对应的是makefile构建系统文档了。
对于gn可以执行
gn help这是一个非常广泛的内置帮助，如下：
PDC-XRseries@AwExdroid94:~/workspace/openHarmony_lzc$ gn help deps deps: Private linked dependencies. A list of target labels. Specifies private dependencies of a target. Private dependencies are propagated up the dependency tree and linked to dependent targets, but do not grant the ability to include headers from the dependency. Public configs are not forwarded.可以看到使用方法。
linux环境下下载好源码就可以开始探索了：
//根目录下执行 tree -L 1 //可见 . ├── applications ├── base ├── build ├── build.py -> build/lite/build.py ├── developtools ├── device ├── docs ├── domains ├── drivers ├── foundation ├── kernel ├── ohos_config.json ├── out ├── prebuilts ├── test ├── third_party ├── utils └── vendor编译的流程如下：
其中在 /Harmony/device/xradio/xr806/ohosdemo 路径下的是一些基于系统的测试用例
都是已经写好了的，可以直接调用
调用方法如下
-
编辑器打开上述路径下BUILG.gn文件如下
group("ohosdemo") { deps = [ #"hello_demo:app_helo", #"iot_peripheral:app_peripheral", #"handsome_demo:app_handsome", #"wlan_demo:app_WlanTest", ] }要执行哪个task直接取消“#”的注释就可以了
修改后记得保存文件！
接下来我们来看看hello_demo的效果
-
注释掉之后，回到根目录Harmony执行
hb build -f生成的镜像文件会存在
Harmony\device\xradio\xr806\xr_skylark\out\xr_system.img 这个路径下，然后在windows系统下打开（也有Linux下的方法，这里就不展开了）
\device\xradio\xr806\xr_skylark\tools这个路径下的工具phoenixMC.exe烧录工具
-
打开后，链接开发板，通过设备管理器确认com口编号（一般是会显示ch340，如果没有安装驱动的话，百度安装一下就好了）
如果识别不到com可以尝试拔插一下数据线，点击刷新。
串口传输速度可以调快一点，选择好固件后点击升级固件
烧录完成
4.烧录完成后需要复位一下，按下rst后通过串口助手，选择好自己电脑上的com口查看输出信息，也可以提前从main文件里修改它打招呼的姿势
比如说：
输出成功！
接下来会放出更多内容。

回复: F133评估版烧写固件后串口没有反应，求助发布在 D1系列-RISC-V
记录一下修改过程中踩的坑。
1. 新建方案过程中的命名规则，格式一定要跟原来sdk中的内容格式尽量一致，什么时候用"_"和什么时候用"-"要区分清楚。
2. 新建了方案后一定要记得重新执行
source build/envsetup.sh不然修改内容没办法更新。
3. target中的common是共用的，芯片一致的情况下其实不用重复新建这个文件。
4. 最最最重要的一点是一定要根据开发板去配置device中的文件，之前刚拿到sdk的时候就想当然觉得大家应该用的都是一样的串口，后来查阅芯片手册，对比device中的板级配置才发现其中的不一样，如这是芯片手册中的配置：
而下面的board文件的配置：
端口不一样，所以串口当然看不到东西了。
同理，其他配置也需要根据不同开发板的原理图改动。

顺便附上一个哪吒的修改例子

回复: F133评估版烧写固件后串口没有反应，求助发布在 D1系列-RISC-V
直接把代码拉下来之后，编译f133evb的选项，生成的镜像无法使用。（串口看不到烧录信息，一般应该有log，烧录软件可以正常烧录，完成后回车没有反应，从头到尾没有任何log信息从串口输出） ，这种情况是要修改什么地方呢。
之前用的是修改D1的方法，没有类似问题

在哪吒sdk中新建D1s方案的方法发布在 D1系列-RISC-V
1、在device/config/chips/d1/configs下新建文件夹命名为d1-d1sevb，将同文件夹下的nezha的内容复制过去，并按照参考文章修改文件内容。
链接文本2、package\allwinner\alsa-conf-aw\files\d1下新建文件夹d1-d1sevb，同样将同文件下nezha中的内容复制过去。
3、在target/allwinner下新建文件夹，命名为d1sevb，并将同文件夹下d1-nezha中的所有内容复制到d1sevb中，并修改文件名，及文件中的内容，使其指向d1sevb项目。
PRODUCT_NAME := d1_d1sevb PRODUCT_DEVICE := d1-d1sevbmakefile中修改：
BOARD:=d1-d1sevb BOARDNAME:=d1-d1sevbTinaProducts.mk中修改：
PRODUCT_MAKEFILES := \ $(LOCAL_DIR)/d1_d1sevb.mkvendorsetup.sh中修改：
add_lunch_combo d1_d1sevb-tina4、根目录执行
souce build/environment setuplunch后可以看到有新增的编译target
选择d1sevb，编译生成镜像，pack打包后用PhoenixSuit烧录。
成功进入系统。

回复: F133评估版烧写固件后串口没有反应，求助发布在 D1系列-RISC-V
@xiaowenge 这个固件没有问题，看来是我编译镜像的问题了。我编出来的镜像能烧录进板子，但烧录过程中和烧录完成之后串口都处于卡死状态，莫非是我的sdk有问题？

回复: d1 sdk里 lichee/linux-5.4/drivers/video/fbdev/sunxi/lcd_fb/include.h 引用了riscv平台不存在的 <asm/memory.h>发布在 D1系列-RISC-V
同样遇到了这个问题，是在f133里面。第一次编译过程中有一些支持选项，选上貌似就不能正常编译。后来全部选择n以后编译倒是通过了，系统能不能正常起来还待验证。

如题，烧写完f133的镜像后串口没有任何反应，有没有大佬能提供一个可以正常工作的固件，还有自己的固件不知道为什么选择了一些视频功能插件就没办法正常编译。
