In a derictory, i put all .cpp and .h files
In command line, I control all motors
I try this simulink model
and get this error
### Starting build procedure for: afmotor_v21

Top model targets built:

Hi Dominique,
It seems that you were not able to run the s-function modules. The issue stems from the "S-function modules" entry in the S-function dialog box in the simulink model. Please note that file names should be entered here without the ".c" extension. The error is thrown because "dc_motor_wrapper.c.c" could not be found, not "dc_motor_wrapper.c".
with regards,
Gokul Nath S J
