【测评有奖】Gokit3开发板乐鑫模块串口诊断教程

可乐丸子

gokit3S开发板在使用乐鑫模块时需要注意不能接底板，笔者早前接了底板连接不了还以为模块有问题，这里告诉Gokit3S新用户，乐鑫模块使用SOC插槽连接到功能板，然后通过给功能板的MicroUSB口上电即可正常使用
下面介绍串口诊断乐鑫模块的方法，首先准备USB转TTL串口的连接线，将USB转串口线的TX RX GND连接到功能板上面的RX TX GND，如下图所示


然后将USB转串口线的USB头插入Windows电脑USB口，在电脑上安装USB转串口驱动，可以使用驱动精灵（驱动人生）解决，然后按Win+PauseBreak打开设备管理器，在端口分支下面会出现安装的USB转串口设备的名称和串口号COMX，其中X为数值需要记住
接着下载Putty或者SecureCRT串口终端软件，连接类型选择Serial，然后把COM后面数值改成设备管理器里面的数字，这里是4，在Speed（波特率）里面填115200


接着选Open打开并给功能板上电即可看到如下串口打印信息
