#176556 - 89s52 communication with visual basic |
i am controlling a small machine having 16 input and 16 output using microcontroller 89s52.i am getting the all input data through serial communication with pc using vb.instead writing complicated logic in mc i am writing logic in vb platform and updating the o/p in every programme cycle.mainly my pc work as cpu and mc work as i/o interface.the reason of using pc is that i have devloped some HMI programme to opearte the m/c through pc.now i want to control 64 i/o using the same m/c and pc. how would i do so. |
