<h1 style="color: black; text-align: left; margin-bottom: 10px;">1-入手</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">儿童<span style="color: black;">tel</span>手表，是为小<span style="color: black;">孩儿</span>设计的。<span style="color: black;">能够</span>定位、<span style="color: black;">能够</span>语音、<span style="color: black;">乃至</span><span style="color: black;">能够</span>拍照。<span style="color: black;">通常</span>不需要功能花里胡哨的，不要有什么视频啊游戏的。基本上<span style="color: black;">通常</span>三五百块钱比较<span style="color: black;">恰当</span>，性价比就还<span style="color: black;">能够</span>。但<span style="color: black;">近期</span>在大妈家见到了几款19元的儿童手表（<span style="color: black;">通常</span>标价219，领取叠加优惠券：满212减200元）。去了10元邮费，还剩9元的成本，令人惊掉下巴。。。墙裂的好奇心，<span style="color: black;">促进</span>我买了一单，尝个鲜儿。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">2-外观展示</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">整体做工还<span style="color: black;">能够</span>，玩具级别，中规中矩，<span style="color: black;">针对</span>19元<span style="color: black;">来讲</span>是绝对值得买的。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">开机之后，跳出的是个二维码，需要扫码激活交费，开通套餐。套餐倒是<span style="color: black;">亦</span>不是很贵，<span style="color: black;">然则</span>看评论好多家长都反应，充值了激活不了，反复充值激活，还存在有时乱扣费的问题。<span style="color: black;">期盼</span>商家能积极改善服务。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">然鹅，值得一提的是，<span style="color: black;">所说</span>的内置卡并<span style="color: black;">不可</span>用普通的手机卡代替，必须激活自带的儿童手表专用卡并购买套餐 。果然，变的有意思了。。。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">HS8225L是一款完整的CMOS高功率，<span style="color: black;">有效</span>率發射模組，適用於低成本四頻TX（GSM850 / EGSM900 / DCS1800 / PCS1900）/雙頻RX GSM / GPRS手機。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">RDA8955</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">紫光展锐旗下锐迪科微电子（以下简<span style="color: black;">叫作</span>“RDA”）推出一款物联网2G芯片RDA8955。该芯片<span style="color: black;">拥有</span><span style="color: black;">全世界</span>最小尺寸及超低功耗的特点，是2G物联网市场最具性价比的<span style="color: black;">处理</span><span style="color: black;">方法</span>。不查不<span style="color: black;">晓得</span>，这个芯片性能还是非常强劲的，配置足够强大。简单说下参数：32位XCPU RISC core ， 312MHz 。32Mb PSRAM 32Mb SPI NOR Flash。外围继承了相机、Audio、SD卡、USB1.1、LCD、37个GPIO口。尤其内部集<span style="color: black;">成为了</span>电源管理模块，<span style="color: black;">能够</span>管理锂电池充电。<span style="color: black;">亦</span><span style="color: black;">能够</span>配置LDO输出用于支持LCD、键盘背光等。这比平日玩的单片机、aduino等不论是性能还是配置的丰富程度都不是一个级别的。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">我<span style="color: black;">无</span>看到GPS<span style="color: black;">关联</span>芯片，说明仅仅是<span style="color: black;">经过</span>2G基站进行定位的，<span style="color: black;">亦</span>就<span style="color: black;">寓意</span>着定位精度不会很高。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">5-刷机</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">必须激活套餐<span style="color: black;">才可</span>用，何解？。。。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">经过</span>对主板的一番观察，<span style="color: black;">发掘</span>主板上存在串口的测试点，并且印刷上了标注Tx，Rx，于是果断飞线，连接上串口转USB输出的模块，连接电脑，打开串口。开机，此时串口的输出就像脱了钢的野马，一顿狂奔。。。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">其中，最重要的就这句log了，直接<span style="color: black;">通知</span>了LCD屏幕的<span style="color: black;">详细</span>型号：</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">此刻我想刷个机。。。然鹅，搜遍全网，貌似<span style="color: black;">无</span>对应固件。</span></p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">6-写固件</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">看来只能另起炉灶了，搜啊搜，搜啊搜……</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">就看到了安信可的一个2G物联网GPS定位模块A9/A9G，用的<span style="color: black;">亦</span>是RAD8955这一款芯片，是有支持二次<span style="color: black;">研发</span>的SDK。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">经过</span>安信可的二次<span style="color: black;">研发</span>sdk，<span style="color: black;">亦</span>能实现自己的<span style="color: black;">有些</span>想法。<span style="color: black;">例如</span>，在<span style="color: black;">微X</span>里跟踪手表的位置，还有安信可自己<span style="color: black;">研发</span>的app<span style="color: black;">亦</span><span style="color: black;">能够</span><span style="color: black;">表示</span>位置。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">19元的儿童手表，有屏幕，有电池，有外壳。比单买这个模块都要更香<span style="color: black;">有些</span>，定制完自己的固件，<span style="color: black;">亦</span><span style="color: black;">能够</span><span style="color: black;">根据</span>自己的想法实现<span style="color: black;">有些</span>特殊功能，<span style="color: black;">例如</span>隔一段时间唤醒自己上报一次位置，<span style="color: black;">这般</span>待机时间就会大大延长啦，你看他是个屏幕不亮的儿童手表，其实它是个定位器，还能指挥录音和拍照，简直是个神间谍。。。</span></p>
