【干点啥好咧】扯扯犊子

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">先上个渣图镇楼</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">昨天收到的开发板</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">一块RSL10-SENSE-DB-GEVK,比较小巧</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">纽扣电池供电,板上一堆传感器</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">一块jlink lite,然并卵,话说已经忘记之前提交的创意要干了,捉急</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">一颗2302电池和一片NFC线圈</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">然后是usb数据线和下载线缆</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">RSL10-SENSE-DB-GEVK装上电池,绿灯爆闪一下,致盲2秒<img height="28" src="https://bbs.eeworld.com.cn/static/editor/plugins/hkemoji/sticker/facebook/dizzy-face_1f635.png" width="28" /></span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">待我CD一下</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">&hellip;&hellip;</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">想不起来要做啥,先扯扯犊子吧</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">在论坛找资料的时候,发现早在8102年,就和这个RSL10结下了梁子</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;"></span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">完全没印象收到过这个样片</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">管管,我的样片呢?</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">快点还我<img height="53" src="https://bbs.eeworld.com.cn/static/editor/plugins/hkemoji/sticker/facebook/wanwan59.gif" width="48" /></span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">拿曾经用过的xDIC 52xxx BLE5.0 SOC(以下简称DIC)和这颗RSL10(以下简称RSL)比较一下</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;"></span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">RSL10的优势还是有一些,简单看了一下</span></span></p>

<p style="text-align:justify"><span style="color:#c0392b;"><strong><span style="font-family:Arial;"><span style="font-size:20px;">红色框框里头</span></span></strong></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">DIC最大发射功率只能到4dBm,RSL可以到6dBm</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">换句话说,DIC手册上给出的最大传输距离大约10m,RSL则可以超过10m</span></span></p>

<p style="text-align:justify"><span style="color:#f1c40f;"><strong><span style="font-family:Arial;"><span style="font-size:20px;">黄色框框里头</span></span></strong></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">1Mbps的信号接收灵敏度,RSL低至-94dBm</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">个人理解,大概意思是RSL可以在更差的信号环境或者更远的距离达到1Mbps的传输速率</span></span></p>

<p style="text-align:justify"><span style="color:#3498db;"><strong><span style="font-family:Arial;"><span style="font-size:20px;">蓝色框框里头</span></span></strong></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">同样的电源和发射功率情况下,RSL比DIC消耗更少的电流,这是BLE门槛</span></span></p>

<p style="text-align:justify"><span style="color:#27ae60;"><strong><span style="font-family:Arial;"><span style="font-size:20px;">绿色框框里头</span></span></strong></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">DIC是个M4内核,而RSL是M3+DSP双core,但是RSL DSP核只用于音频的编解码</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">这表明RSL是为语音而生,DIC去传输语音估计得跑出翔</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">要是能把这个DSP骗出来用,得上天</span></span></p>

<p style="text-align:justify"><span style="color:#000000;"><strong><span style="font-family:Arial;"><span style="font-size:20px;">黑色框框里头</span></span></strong></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">这就厉害了,RSL深度休眠0.05uA,远远低于DIC的0.4uA</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">即使RSL保持住8k的RAM,也才0.1uA,甚至比DIC完全深度休眠的0.4uA也要低不少</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">另外</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">RSL的电源也是比较骚,1.1v-3.3v,单节AAA电池撸上就完事了</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">骚就一个字</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">不过DIC在其他硬件配置上也有自己的特点</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">比如硬加密,比如任意的IO映射矩阵</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">RSL是咋样的,还没深入了解,后边再吹水</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">总的来说,RSL10这颗BLE5.0 SOC在功耗方面应该是可以完胜市面上大多数同类了</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">SDK方面,还没看,希望不要有陨石坑,这个很重要</span></span></p>

<p style="text-align:justify"><span style="font-family:Arial;"><span style="font-size:20px;">以上</span></span></p>

<p>好一个8102年:pleased:</p>

<p>因为8102年给楼主的,所以楼主没收到<img height="48" src="https://bbs.eeworld.com.cn/static/editor/plugins/hkemoji/sticker/facebook/lol.gif" width="48" /></p>

<p>对比标识很清晰啊</p>

<p>一目了然</p>

<p>看来搭配DSP的SOC功耗果然很有优势</p>

一目了然

看来搭配DSP的SOC功耗果然很有优势

<p>看上去比较美</p>

<p>可能两者的目标用户、价格都不太一样,拿来对比可能有失偏颇</p>

<p>一个针对语言传输,一个普通应用</p>

<p>不过还是有肉眼可见的差距,至少在手册上是这样</p>
