2023-6-13 外壳V1.2
     对比V1.1外壳,做出以下调整:         1)厚度减小0.4mm到10.6mm         2)采用PCB或自己裁切的铝片(厚度均为0.8mm)作为后盖,安装方式为4颗M1.4*3.5的沉头自攻螺丝!切记,螺丝很重要!相关的PCB和铝片螺丝孔位置需要自行
                做好沉 孔倒角处理。         3)正面斜面角度改大,由原来的45°倒角增大到60°(附近,具体忘了),观感个人认为有所提升         4)后盖PCB文件在开源工程页面有提供,铝片需要自行建模去CNC或者导出PCB外形层进行激光雕刻
 
材料说明:         需要使用  尼龙激光烧结(嘉立创就有,但是要注意提醒那边不要进行任何缩放,不然可能工厂擅自放大了一点回来松垮垮的)   或类ABS、类尼龙(更推荐)树脂进行         光固化打印,普通树脂打螺丝(V1.2)和扣后盖(V1.1)会碎,FDM打印的几乎不能用,不在考虑范围内,如果需要CNC金属,需要对模型进行一定修改
 
2023-5-16 固件V1.0.3        ESP32-S3:                修改:步数显示改为电池电压显示                优化:屏幕刷新率由90降低至77帧,降低显示竖纹提升观感                          记忆功德数、屏幕亮度、表盘界面,息屏唤醒后保留原有状态                          指针表盘中心点对齐优化        HC32:            无
 
 
2023-5-4  固件V1.0.2            新增:赛博修仙-->数字表盘左滑进入,随时随地积攒功德                      POP猫-->指针表盘右滑进入,随时随地阿巴阿巴            修改:指针表盘的圆弧震动测试关闭,修仙和阿巴阿巴均可有震动反馈            优化:屏幕刷新率由60帧提升到90帧,纵享新丝滑                       息屏唤醒时间打骨折,由原来的1.7s左右优化到200ms以内
 
2023-4-26 固件V1.0.1    新增:HC32的串口全双工中断死机问题解决,可以稳定当手表日常佩戴看时间使用了,目前测试暂时再未出现过死机
 
2023-4-23 固件V1.0.0    新增:
              ESP32S3-手表显示时间功能固件,适配LVGL官方手表demo为240*240分辨率,界面适配为楷体中文,目前仅可用于看时间和电池电量,
                     其余 功能暂未适配              HC32-电源管理、RTC时钟、IIC设备扫描             屏幕亮度、振动器操作,数字表盘左下角arc更改亮度,指针表盘arc设置震动
             V22原理图和PCB,对比V21多了一颗电容,具体(抽风的违禁词识别)位置打了V21板子的同学可以去原理图看一下根据提示加上去就行,无需重新打板   
             版本特性:超低功耗,充满电正常使用看时间,预计最少可用2个月
             已知问题:有一定概率HC32硬件死机,它的串口功能暂未做半双工适配,死机后用串口助手重启HC32即可
 
下载步骤:    如没装过CH343的驱动,需要安装一下,只装了CH340的驱动仅能识别COM口,下载会报错,驱动在资料包里有    ESP32S3:按照ESP32S3的固件包内的配置步骤使用download tool进行烧录下载,烧录结束后点击stop后使用提供的串口助手按照提示重启一下ESP32S3    HC32:按照配置内容使用XHSC下载器选中固件HEX进行下载即可,烧录结束后使用提供的串口助手按照提示重启一下HC32
 
配置步骤:(发送指令和扫描设备期间手需要一直触摸屏幕保持手表常亮)    配置时间:通过串口助手发送格式为:如(time230423113605),括号为英文状态下的,time指设置时间,23为23年,04为四月,23日,11时,36分,05秒,每一个参数固定占2位,不足补0,发送完后时间立即更新至显示,日期需息屏重新唤醒后才会更新    扫描IIC设备:发送指令(scan),括号为英文状态下的,通过扫描设备可以知道磁力计、imu、气压计、库仑计焊接是否存在问题
 
关于外壳:
    1)23-4-17更新了V1.1版本外壳,优化了按键部分,解决了V1.0版本的偶尔回弹卡顿不舒服的问题
    2)一个比较好的打印方案:采用黑色类尼龙树脂打印,实测效果非常好,完全解决了刚性树脂易碎、起白色痕迹的缺点,打印出来只需要对支撑点进行简单打磨即可,无需精细打磨和喷漆等操作就能获得一个非常好的效果,后盖安装也完全ok不再怕卡扣碎裂,缺点就是类尼龙树脂比较贵(50元250克),为了这个外壳我甚至买了台光固化。。。
 
关于硬件:
    1)新增了V2.2的PCB和原理图,这些小细节的优化会让体验提升很多,发现了HC32L110的一个硬件bug:串口开启中断的情况下,全双工发数据非常容易触发死机,这点就非常难受了,软件上只能做半双工用了
    2)程序烧录:按住按键即可烧录副处理器HC32(不按是烧录ESP32S3),HC32烧录完后不会自动复位重启,需要用串口助手uartassist开关一下RTS信号重启HC32
    3)屏幕使用的型号是 8080接口 带TP IF10,就是触摸盖板狗啃的一样那款,搜1.28寸触摸就行
    4)使用的电池是R40350V 435mah 3.85V圆形电池
    5)使用的表带:插针式20mm宽度表带全通用
    6)使用的振动器:0820  直径8mm,厚度2mm的扁平振动器
    7)焊接注意要点:①所有元器件焊接完成后再焊振动器,振动器上面贴的双面胶和海绵都要刮掉减小厚度,②中龟按键平整的一面向着屏幕,四个脚悬空用锡焊到焊盘上,③在焊接按键和振动器时,将PCB和元件放在平整的平面上压紧焊以保证接触屏幕的一面平整
    7) Assembly process: ① Install the buttons first, ② Place the screen diagonally on one side of the cable, and then install it smoothly. ③ On the side of the motherboard that is attached to the screen, all exposed pads must be cleaned very flat and without tin burrs, and then Use an oily marker or other pen with a certain insulating effect to blacken the solder joints. If possible, you can apply solder resist, but be sure to make sure it is flat and will not touch the screen. ④ First align the motherboard with the groove of the keys and insert the keys There, just press it in at the C port on the right side. Pay attention to the screen cable. ⑤ Fasten the screen cable. ⑥ The side with the battery port is just placed at the C port. Arrange the two power cords side by side and smooth them out, otherwise they will Hold the back cover, ⑦ first align the back cover with the two buckles on the side of the screen cable, push in and lock it, and then use your little finger nail or other soft objects to snap the other two buckles in sequence. There are step-by-step
 
hardware diagrams below. Resources:
    1) ESP32-S3 is the core master, responsible for complex calculations and interactive processing, the default is 8M Psram + 32M flash combination
    2) HC32L110C6UA is the sub-processor, responsible for processing low-power tasks
    3) LSM6DSL six-axis attitude sensor, Low power consumption and multi-function coexist
    4) QMC5883L three-axis magnetometer, combined with LSM6DSL, can achieve nine-axis posture fusion
    5) BMP280 barometer, which can measure altitude and ambient temperature
    6) CW2015 coulomb meter, accurately count battery power
    7) 1.28-inch 240*240 resolution circular screen with capacitive touch screen
    8) Vibrator
    9) 3.85V lithium battery charge and discharge management and protection
  
design features:
    1) Both the main and sub-processors can be programmed through the charging TYPE-C interface , no need to repeatedly change any hardware, one use for multiple purposes
    2) Ultra-low standby power consumption, as low as 14uA when turned off, and around 30uA when not turning on the sports function
    3) Close to commercial-grade appearance design
  
About the software:
    1) To prevent certain Speculators resell and will not open source source code. The subsequent fully functional firmware will also add the device certification function, and only bin firmware will be provided.
    2) The design goal of this project is to serve as a somatosensory remote control or touch screen for my personal smart home or remote control drone. The central controller is not aimed at other people. If you have any needs, please don’t mention it. Modify or design it yourself.
    3) This watch can be used as a development board for learning and developing smart watches.
    4) Students with ideas can contact me to participate in the development of firmware. Some
