Program Gives Silly Error And Does Not Complile

Recommended Posts

This following program does not compile with Sourceboost C2C Plus 5.3. It gives the error : Error: General error in function definition on line 72 which is exacltly the same as the code on line 78 namely, clear_bit (portc,RS) ;


I have tried, output_low_port_c (RS); and clear_bit (portc,5); with no success. In general the code may be wrong for what I am trying to do, but it is the syntax that seems to be the problem. I have tried using hex instead of my prefered binary in some statements, but with no success.


Please help me get this going.

Which processor is the target device ?


Looks like you use of macros is messing things up, try changing

#define stndwrite_delay 1 /* 100 */




#define stndwrite_delay() delay_ms( 1 ); /* 100 */


This gets rid of the error to which you refer.

But then I cant complete the build - maybe because I have the wrong target selected.

The device is the PIC16F876.


You advice worked thank you very very much. I was working on this problem for a long time so thank you very very much.
