Platform Independent Code

[Sanath Embedded]

Hi Guys,

I am writing an program for one application in C / C++ which should run on all target controller architecture like 8051 , AVR, PIC , MSP430 or ARM7 . How could I write this Platform Independent Code.

can anyone help me on this.

you should practice writing code in layered structure.. i meant you should write hardware-dependent code and hardware-independent code separately

for example.. check below code that sends string via UART

High-Level or Hardware-independent function

void putsUART(char *str)
{
      while(*str)
          putcUART(*str++);
}

low-level or Hardware-dependent function

void putcUART(char chr)
{
     //hardware dependent code
}

Here u can use High-level function in all architectures but u have to write Low-level function seperately for each architectures..
