Hi, The DYNAMIXEL Simulink Library is a third party library that is not provided by ROBOTIS. Please contact the developer for the issues related to the library. Thank you.

Hi @wnghdwnsrl I´m also trying to use DynamixelSDK with Simulink. So far, the one in MATLAB File Exchange doesn´t work for me. I get callib errors while using the myDxl function. I tried enabling the headers and C functions as mentioned here:

https://la.mathworks.com/help/simulink/ug/integrate-ccode-ccaller.html

In the mean time, I tried some methods to use the DynamixelSDK C library in Simulink. One of them is using C Caller Blocks. With this approach, I could get almost all the function needed to make a read_write example similar as the one available for LabVIEW, but i can´t get it to compile.

The second approach I used was with shared libraries using MATLAB Function Block, as metioned here:

https://la.mathworks.com/help/simulink/ug/incorporate-c-code-using-a-matlab-function-block.html https://la.mathworks.com/matlabcentral/fileexchange/44197-calling-shared-libraries-from-simulink

But, I also having compile errors, and I basically stuck. If you wanna share how you configure the Library (the one made by the MATLAB team) and maybe get it to run, since i can´t get an answer from the original developer.

I'll be sharing my approaches if someone wants to get a look at them and try to get them work as a potential alternative.

Thanks in advance.

Hi,@johncgh22 @wnghdwnsrl

Although it is not a material that can solve your issues directly, I will introduce Dynamixel related resources posted on MATLAB File Exchange. They are wrapped as robot arm that using Dynamixel.

Hi @johncgh22 It was happened by small mistake. I just changed Devicename in "slDxl.m" file ( line 13) DeviceName = 'DeviceName'; to DeviceName = 'myDxl';

then it just worked. I wish it can be helpful to you.

Hi @ROBOTIS-Shibata Thank you for your post.
