Two Microcontrollers Interaction Using C

This paper studied about micro controllers interaction using RS232 as a communication tool and C to programming the interaction. PIC18F4520 will be used in this prototype and MPLAB as a software tool. Before run it into the real hardware, some simulation must be done to make sure all the hardware connection and software writing is correct. Proteus 7.1 has been used for the simulation purpose. The result shows that interaction between micro controllers can be done using those entire gadgets.
