Embedded Programming with Modern C++ Cookbook

How to do it...

Follow these steps to complete this recipe:

1. Open mcu8051ide and create a new project.
2. Create a new file called serial.c and copy the following code snippet into it. This code copies the bytes that were received over the serial link to the P0 output register. This is associated with the general-purpose input/output pins on the MCU:

#include<8051.h>void serial_isr() __interrupt(4) {     if(RI == 1) {        P0 = SBUF;        RI = 0;    } }void main() {    SCON = 0x50;    TMOD = 0x20;    TH1 = 0xFD;    TR1 = 1;     ES = 1;    EA = 1;    while(1); }

3. Select Tools | Compile to build the code.
4. Select the Simulator | Start/Shutdown menu entry to activate the simulator.
