主要是驗證下功能，熟悉下topic。
wsl2和真正的Ubuntu目前使用的主要區(qū)別感覺是端口要映射；

硬件端口映射

可以參考我映射D435i的筆記：在WSL2子系統(tǒng)中跑D345i獲取數(shù)據(jù)

在windows端安裝usbipd工具，最好全程在管理員模式下的cmd窗口操作

winget install --interactive --exact dorssel.usbipd-win

或從GitHub下載安裝：https://github.com/dorssel/usbipd-win/releases
檢查設(shè)備列表，我這兒已經(jīng)連上了

usbipd list

返回

出了可以看到目標COM3，還可以看到之前映射的D435i;
端口是1-14

usbipd bind --busid 1-14
usbipd attach --wsl --busid 1-14

返回

usbipd: info: Using WSL distribution 'Ubuntu-20.04' to attach; the device will be available in all WSL 2 distributions.
usbipd: info: Loading vhci_hcd module.
usbipd: info: Detected networking mode 'mirrored'.
usbipd: info: Using IP address 127.0.0.1 to reach the host.

然后，是在wsl-Ubuntu20中操作了，先用lsusb列出設(shè)備:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 10c4:ea60 Silicon Labs CP210x UART Bridge
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

用lsusb -t檢查具體的口和速度：

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=vhci_hcd/8p, 5000M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=vhci_hcd/8p, 480M
    |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=cp210x, 12M

官方ros包

在官方文檔T-RTK UM982_用戶手冊_V1.1
里面，下載handsfree_rtk壓縮包，下下來后解壓到要運行的ros1的工作空間下的src下

cd & mkdir -p catkin_ws/src

然后執(zhí)行自動安裝依賴和編譯腳本

cd ~/catkin_ws/src/handsfree_rtk/
bash auto_install.sh

實際上我看也主要是給python安裝了pathlib和pyserial，熟悉虛擬環(huán)境可以自己折騰，然后是設(shè)置usb規(guī)則，規(guī)則文件handsfree_rtk：

KERNEL=="ttyUSB*", ATTRS{interface}=="HandsFree RTK USB to UART Bridge Controller", MODE:="0777", SYMLINK+="HFRobotRTK"

其中安裝和啟動規(guī)則文件的語句

sudo cp usb_rules/handsfree_rtk.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger --subsystem-match=usb

通過里面提供的usb規(guī)則和C++demo，可以自己寫自己的ros包，繞開官方的python實現(xiàn)。

然后是官方的執(zhí)行

roslaunch handsfree_rtk handsfree_rtk.launch

不過我在室內(nèi)測試，打印出的都是無效信息：

還是得拿到外面去測下。
