如何高效率地完成NRF51822烧录

<span style="color:#444444;font-family:Tahoma, 'Microsoft Yahei', Simsun;background-color:#FFFFFF;">各位nrf51822开发者你们好，小弟今天再次分享一个nrf51822不太多人讨论的问题--芯片烧录问题。</span><br />
<br />
<span style="color:#444444;font-family:Tahoma, 'Microsoft Yahei', Simsun;background-color:#FFFFFF;">关于NRF51822，其在蓝牙4.0的开发领域占的地位不用说，功耗和稳定都是首屈一指。但关于NRF51822的芯片烧录问题，却也一直是一个让很多开发者困惑的问题。NRF51822仅支持SWD协议对FLASH读写，这对烧录方法便有了很大的限制，传统的做法有两种：第一，芯片贴片前交给烧录公司烧录。有两个缺点，1.价格昂贵（差不多6分钱一片），2.代码需要给到别人，我想这一点是大部分公司都不愿意的。第二，自己用电脑一个个板子烧录，缺点不用说就是效率低。本团队以往便是第二种做法的，大大影响了我们的生产速度，如果是上万片的批量，还怎么生产下去？</span><br />
<br />
<span style="color:#444444;font-family:Tahoma, 'Microsoft Yahei', Simsun;background-color:#FFFFFF;">说到主题了，本着解决这个问题的心态，我们团队自己研发了一款脱机烧录器 NRF-FLY。请大家容我介绍一下这款烧录器的功能：</span><br />
<span style="color:#444444;font-family:Tahoma, 'Microsoft Yahei', Simsun;background-color:#FFFFFF;">仍然基于SWD协议，NRF-FLY只是做到了脱机和多个烧录的功能。如下：</span><br />
