| Problem compiling with AD9850 |
 Posted: Fri Mar 08, 2013 5:09 pm |

Hi! I need help to interface AD9850 with a PIC18F4550. I tried to use the code posted on this page https://www.ccsinfo.com/forum/viewtopic.php?t=48383 but when I try to compile, I see several errors. These are: expecting a (Expecting a declaration, Expecting a identifier). So I ask you whether if you can help me find a solution to the problems of compiling ?.
Thank you in advance. |

The code that the post refers to is not a complete program.
Rather it appears to just be a basic 'driver'. As such it has to be added into your 'main' program.
Without seeing your 'main' program no one here can tell you where you've gone wrong,t hough it could be a simple syntax error.
Post your real program, being sure to include the compiler version.

Thank for rapid reply. The version of my compiler is V4.134. Here you can see the list of program that regards the AD9850
#include <ad9850.h>
AD9850_setup(PIN_C5,PIN_C4,PIN_D3,PIN_D2 );
while(1)
{
AD9850_sweep(20, 100000, 100, 200, true);
}
The errors are in the routine of AD9850, not in the main program |

No, you are missing the point.
The ad9850.h 'driver', needs to have the right settings in your main code _before it is loaded_, or it will not compile correctly. You need to generate a small 'main' program, with fuses etc., then load this driver.
It _will not compile_ without the stuff ahead of it that is needed.
If this stuff is present, the other possibility is that you are using MPLAB, and have added this file to source files in this. It won't compile like this either. It should be in the 'include' files.
Best Wishes |

This was just the part of main with AD9850.h. The complete program,with fuses, is this:
| Code: |
#case
#include <stdlib.h>
#include "Demo.h"
#include <ad9850.h>
//============================================================================
void main() {
setup_wdt(WDT_OFF);
port_b_pullups(TRUE);
output_b(0xFF);
set_tris_b(0b11110000);
set_tris_d(0);
set_tris_c(0);
set_tris_e(0);
set_tris_a(0);
setup_adc(ADC_CLOCK_DIV_64);
#ZERO_RAM
//------------------
AD9850_setup(PIN_C5,PIN_C4,PIN_D3,PIN_D2 );
while(1)
{
AD9850_sweep(20, 100000, 100, 200, true);
} //end loop
} //end main
|
The file "demo.h" is this:

I tried the routine in the link, and report errors..

The first thing you must do is move DEMO.h above the #case statement...
It MUST be the first line in the main program.

Start with two things:
There is no function 'AD9850_setup' in the driver on the page you claim to be using. Not surprising it is not accepted....
Then if you look at the code it is written to use standard I/O mode. |

So, seen that the program is written using standard I/O mode, what can I do to solve my problem?
Thank you very much for reply |

I finally understand the reason I could not run the library.
The problem was that the routine had to be inserted before '#case ' otherwise it would made a distinction between upper and lower case. Thank you all for helping me.
Best regards |
