class="horizontal-splitline normal-bold-2"> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">一个基于WCH公司CH347芯片的综合烧录&测试治具</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;"> </p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">手里本来有一个CH341的芯片烧录治具，但是在使用过程中会感受到这个治具不舒服的地方有两点</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">1.这个治具为USB公头，本人使用的为台式机，导致每烧录一次都需要蹲下来反复拔插这个烧录治具。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">2.CH341芯片烧录速度非常缓慢，一个Falsh需要一分钟左右。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">遂寻找方案来代解决这两个问题。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;"> </p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">经过反复上网冲浪，最终确定较新发布的CH347为本次主要IC。翻看DATASHEET时发现这颗IC有四种工作模式，在群内和朋友吹水时也有想过是否可以在一张板上同时实现这四种模式。经过一些比较小的努力，本想法得以实现并成为本产品。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">CH347一共有四种模式，采用了拨码开关对四种模式的切换，具体功能如下：</p> <p class="paragraph

class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height: 1.8;">烧写方面CH347要优于CH341</p> <p class="paragraph

1.8;">*关于‘要你命3000’名称的由来：因为本人曾对吐槽过一些柔和了过多奇怪功能的专业类型产品（譬如说烙铁能玩贪吃蛇还能看天气），戏称它们为‘要你命3000’（详见周星驰的电影《国产凌凌漆》）。但是本人这次的产品也有一种类似的味道，遂用此名来对此产品进行命名。</p> <p class="paragraph text-align-type-left pap-line-1.3

pap-spacing-after-3pt" style="line-height: 1.8;">而这两个引脚也同时为串口1（常驻串口）的功能类引脚。为了方便随时切换，所以本人将串口1阉割为只有TXD,RXD的非全功能串口。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto
