Using external Motor Driver C-Code in Simulink

Hi,

so i'm trying to utilize external c-code for the motor driver powerstep01.

I've tried to include the necessary .h and .c files to use the c-code via the ccaller-block, but i'm still not able to build the code.

I'm using Matlab R2018b, STM32 Mat-Target, CubeMX and SW4STM32.

The stepper motor driver software expansion for STM32Cube i'm using is X-CUBE-SPN3.

It would be nice to get some general information about which steps i should be following to generate the code.

Thanks for your Help

Best regards Tom
