拓展2：FishBot配套雷达驱动教程（源码版）
-
@小鱼 有调到串口，orangepi上面cutecom都可以收到串口的数据。
-
@mmmkmmm 驱动里的串口号改了没，改了后有没有重新构建
-
@小鱼 进入到源码，修改串口编号ydlidar_ros2/params/ydlidar.yaml，一般是/dev/ttyUSB0
ydlidar_node:
ros__parameters:
port: /dev/ttyUSB0
frame_id: laser_frame
ignore_array: ""这里已经有改了。
-
@mmmkmmm cutecom 看这个口有数据吗，这个口确定是雷达吗，有没有重新构建，接线是怎么接的
-
此回复已被删除！ -
@mmmkmmm 看起来也是没问题，你到eai官网找找驱动工具测试一下看看
-
@小鱼 EAI官网那个工具有下来测试了，WIN系统下，工具就死机了。orangepi 上面还没试。现在有没有一种可能，是供电问题？看官网手册上面有提到这点？

@小鱼 使用官网的EAI雷达测试工具，输出以下日志：

你好，现在orangepi上面报Failed to get scan 这个是什么原因？

@mmmkmmm windows上的，板子没有设计DTR,后面的检测失败正常
-
@mmmkmmm 有电脑端吗，之前测试过wifi的方案吗
-
@小鱼 是不是这个雷达板有问题啊，用官方的工具，启动雷达也不行
-
@mmmkmmm 你手里是哪个版本的雷达
-
@mmmkmmm 全新雷达不是X2
-
@小鱼 是全新的雷达，公司采购刚在你们店新买的。
-
@mmmkmmm 全新雷达是F2，带激光强度信息的，这个工具不支持
-
@mmmkmmm 有测试过快速上手教程吗
-
@小鱼 就是按上面的快速上手，一直不行，上面教程又说是X2雷达，那这款雷达相应驱动、教程有没有？
-
@mmmkmmm 这个帖子不是快速上手教程，你按照快速上手教程试试
-
@mmmkmmm 快速上手教程走的是wifi驱动，不是有线方式
