Hi dreamk,

you need to write two fully different programs, one for your PC and another for the 8051.

But at first, you must decide or develop a communication protocol to send data from one to the other, e.g. over the UART.

Also you can develop for the 8051 in C, but not in C++, e.g. on using the Keil C51 compiler. For your small task, the 2kB evaluation version should be sufficient.
