[SOLVED] [Moved] My first program for LED Blinking

[maxim10373]

I am trying to make a program for AT89c2051 LED blinking.
I download a sample program I attaching here.I used MIDE
Studio.I pasted the C program on new window and save
.asm mode.but there are more than 48 errors showing.
please help me for making a true program

Maxim.

Test your board with myfirst.c, a simple c program
that makes LED blink every 0.5 second.

The error is of Header file.
Go through the below link, check the section of header files in it and download the file reg2051.h at where your set up files of the software is.

If it doesn't work then post your errors here.
