连接串口模块

DongshanPI-PicoW属于最小开发板,可以直接使用 5V电压输入 即可开始工作,可以参考下图所示,使用 串口 模块 分别连接P42 TX连接至USB串口模块RX引脚P43 RX连接至串口模块 TX引脚P46 GND连接至串口模块 GND,另外 可以选择 P31 5V连接至串口模块 5V电压输出,确认好连接后,可以通电连接至 电脑USB接口,板子会默认启动,可以通过串口工具等 打开串口 进入系统。

注意: 一定要确保串口模块 5V GND与开发板的P31 P46 连接无误,才能通电,否则 会导致硬件损坏,我们不予处理。

如下使用了一个USB转串口模块和板子的连接示意图,可以用来参考,一定要注意线序和usb转串口模块对上!

使用串口登录系统

1. 连接串口线

将配套的TypeC线一段连接至开发板的串口/供电接口,另一端连接至电脑USB接口,连接成功后板载的红色电源灯会亮起。 默认情况下系统会自动安装串口设备驱动,如果没有自动安装,可以使用驱动精灵来自动安装。

  • 对于Windows系统 此时Windows设备管理器 在 端口(COM和LPT) 处会多出一个串口设备,一般是以 USB-Enhanced-SERIAL CH9102开头,您需要留意一下后面的具体COM编号,用于后续连接使用。

QuickStart-01

如上图,COM号是96,我们接下来连接所使用的串口号就是96。

  • 对于Linux系统 可以查看是否多出一个/dev/tty<> 设备,一般情况设备节点为 /dev/ttyACM0 。

QuickStart-02

2. 打开串口控制台

获取串口工具

使用Putty或者MobaXterm等串口工具来开发板设备。

使用putty登录串口

QuickStart-04

使用Mobaxterm登录串口

打开MobaXterm,点击左上角的“Session”,在弹出的界面选中“Serial”,如下图所示选择端口号(前面设备管理器显示的端口号COM21)、波特率(Speed 115200)、流控(Flow Control: none),最后点击“OK”即可。步骤如下图所示。 注意:流控(Flow Control)一定要选择none,否则你将无法在MobaXterm中向串口输入数据

Mobaxterm_serial_set_001

3. 进入系统shell

使用串口工具成功打开串口后,可以直接按下 Enter 键 进入shell,当然您也可以按下板子上的 Reset复位键,来查看完整的系统信息。
