Esp32 and YDLIDAR X3 PRO #16

Hello,
look at the library sample sketches. The sketches print out distance and
angle data to the Serial Monitor.
- install the LDS library in your Arduino IDE
- open the YDLIDAR X4 sample sketch from LDS library, File -> Examples ->
LDS -> sketch name
- change the #include in the sketch from YDLIDAR X4 to X3 PRO. See the list
of available include files in LDS/src folder
- change the Lidar class from X4 to X3 PRO; read the X3 PRO include file to
find the class name
- note Lidar pin names and corresponding GPIO numbers in the example sketch
- note how the sketch prints out distances and angles to Serial Monitor
- compile your sketch, make sure there are no errors
- read the X3 PRO datasheet to find the pinout for your X3 PRO here
https://github.com/kaiaai/awesome-2d-lidars
- connect your X3 PRO power to 5V 1A; connect your Lidar signal pins to
ESP32 GPIOs noted in the sample sketch
- test your sketch with your Lidar; use the Serial Monitor in the Arduino
IDE to inspect the distances and angles

Don't use the serial adapter. Connect your Lidar to ESP32 pins.
The serial adapter is necessary only if you want to connect your Lidar to a
PC or Raspberry Pi/etc.

There is no data on the serial Monitor. I connected 5V, TX(ttl) to
RX(esp32 16pin), RX(ttl) to Tx(esp32 17pin). Thank you so much about your
fast response. I am still expecting your response :)

I use ROS2 RViz for Lidar visualization, but it works with robots that have
a Lidar.
I don't have anything else. I'd suggest writing a Python script that
receives text over a COM port from the Serial Monitor and plots the
angles/distances the way you like it.

I'd suggest googling. There are denoise algorithms out there.

Sometime distance is 0. It is very big noise on the autonomous system.
Is there any solution?
