Hi, I have a project using RPLIDAR A1M8, Dynamixel MX-64 and two motors with encoder to make 3D scan with 2D lidar.

Connectting and using each thing was not that problem. and I made it act step by step (scan -> turn lidar -> move -> scan ....).

I tried it to act parallel but I can't load library in parpool. It showed error.

So I'm trying to make it in Simulink. (I think it will be more convenient because motor PID file is simulink file.)

But it showed error too.

when I use

hardwarex_init;

this mfile is

%hardwarex_init
if not(libisloaded('hardwarex'))
    addpath('.');
    switch (computer)
        case 'PCWIN64'
            addpath('x64');
            %loadlibrary('hardwarex', @hardwarex_proto);
            [notfound,warnings]=loadlibrary('hardwarex', @hardwarex_proto);
        case 'PCWIN'
            addpath('x86');
            %loadlibrary('hardwarex');
            [notfound,warnings]=loadlibrary('hardwarex', @hardwarex_proto);
        otherwise
            %loadlibrary('hardwarex');
            [notfound,warnings]=loadlibrary('hardwarex', 'hardwarex.h', 'includepath', 'MAVLinkSDK', 'includepath', '/usr/local/include', 'includepath', 'sbgECom/src', 'includepath', 'sbgECom/common', 'includepath', '/usr/local/include/sbgECom/src', 'includepath', '/usr/local/include/sbgECom/common', 'includepath', 'rplidar_sdk/sdk/sdk/include', 'includepath', 'rplidar_sdk/sdk/sdk/src', 'includepath', '/usr/local/include/rplidar_sdk/sdk/sdk/include', 'includepath', '/usr/local/include/rplidar_sdk/sdk/sdk/src');
    end
    %libfunctions hardwarex -full
end
