I follow the instruction on the MATLAB website - Drive with PID Control on an Arduino Mega 2560, I simulate the closed loop PID control on the Simulink successfully. But when I click to Deploy to the Hardware, it failed and gave the error message - undefined function or variable "scomp". I googled the word "scomp". There is not relevant result and I really cannot figure out the problem. Thank you for the help!
