Cmake issue on windows 10

[Jiaxin-lim]

Hi, i am getting the error while cloning.

Is that the reason why i am getting the error of:
'cmake' is not recognized as an internal or external command,
operable program or batch file.
while trying to build sick_generic_caller with cmake and Visual Studio 2019.

Any ways that i can resolve this issue? thank you.

Thanks for your report. To run cmake from the command line, it is recommended to download and install cmake from https://cmake.org .
According to the Visual Studio screenshot, cmake seems to be installed successfully by vcpkg. The error message "CMake Error (find_package)..." suggests that a package is missing. Please provide the complete error messages with further details.

Thank you. I had managed to successfully installed it.

Would just have 1 more question which is how do i write my own python scripts to send and received signal/tele command to my 781s Lidar?

To handle Lidar data and commands in python, you need to implement an UDP receiver for the lidar data and a TCP sender and receiver for the lidar commands. Receiver and sender have to parse and handle the lidar data and telegrams according to the specification (manuals and telegram listings for your lidar).

Where can i get the manuals for the 781s Lidar?

Please have a look at our homepage www.sick.com. There, you will find all the technical documentation for the appropriate device.

Click on the link to open the manual directly.

Maybe this link could help: https://www.sick.com/de/en/detection-and-ranging-solutions/2d-lidar-sensors/tim7xx/tim781s-2174104/p/p594149

@reinbja the link does work for me, i could'nt get to the manual directly.
@michael1309 i had tried the sick website and there isn't any manual there for me to refer to beside the telegram listing and operating instructions

Handle the data with your own application requires the implementation of the full command stack using the SICK specific SOPAS command. It is much easier for you if you use this generic driver and push the lidar data to your own application by an online connection (like pushing data over udp or similiar) or by using a pipe or file. An excellent starting point for this would be the following line in the code

sick_scan_base/driver/src/sick_scan_common.cpp

Line 3767 in 9e0e0cd

if (cnt == 25)

Here are all lidar data available and you replace the jpeg export etc. with your own implementation.

Here is the specific link for the command communication. Compare the commands given their with the log output after starting the driver. This will give you in combination with source code inspection a clear understanding of the communication. In addition you can use wireshark to see the "real data" on wire:
