I want to exchange information between CarMaker and Simulink using ROS2.
However, the manual does not provide C code for obtaining the spring length.
How can I get the spring length shown in the image?
I tried to search for the C variable usage within CarMaker, but it seems to be buried deep in the code, making it quite difficult to pinpoint. I believe your best approach would be to use the UAQ (User-Assigned Quantity) for this.
If it’s absolutely necessary to use a C variable, you can simply assign the value of the UAQ to a C variable that you have declared.
Good hint @alejandro.moreno. Also @geantae since you are already using simulink in your toolchain, you could also use the simulink variable mentioned in the manual lSpring <'pos>
Thank you for your response.
Can I use the function in the picture to retrieve and use a variable defined as UAQ?
I tried to use it this way, but I’m having trouble merging cm4sl and CMRosIF.
