Syntex error near(c141) error

Krunal Makwana

I am using At89x52 microcontroller in the solar tracker.
I use the ADC MCP3208 to connect the two ldr and convert it into digital signal by ADC MCP 3208.

But,it shows syntex error in code. Help me with this


#include<at89x52.h>

    That's usually an indication that you have completely confused the compiler!

    So, as I said, look back over the preceding lines for mistakes.

    There are some big ones!

    What do you think this line does:

    #define ADC_CS=P1^5;

    And this:

    #define p1

    I think you need to re-read the section on preprocessor definitions in your 'C' textbook

    In particular, these are preprocessor directives - not 'C' statements - so they should not end with semicolons (unless you want the semicolon to form part of the definition).

    Those preprocessor definitions will completely mess up the code that follows - hence the bizarre error messages!

    This is all standard 'C' stuff - not specific to Keil or 8051.

    Here are some 'C' learning & reference resources - including a free online 'C' textbook:
