Hi, can anybody help me on this project. I need to control 20 stepper motors and 6 diodes. I have experience in project using pic16f887 etc. But i have never used port expander and/or assemblies using more than one microcontroller. So, i thought of two solutions:
1. Using 2 microcontroller as an input in the system (of encoders and photo sensors, and the code from pc [this will be via usart]), and then somehow the signals should be multiplexed and sent to appropriate microcontroller, which will control several stepping motors.
2. Or using similar solution but also using a port expander.
So is there anyone who can help with a solution for controlling so many actuators and choosing the right microcontroller.
