syntax error using Mplab c18

[bethel]

Hi,
i got a problem with my project..
I get a syntax error while compiling the program on mplab c18 , same program was compiled in another c program compiler and hex code generated but I only have access to
mplab c18.... can i get help to get the program compiled to hex file

I get a syntax error while compiling the program on mplab c18

This question is for guessing what error is this ? If you are new in programming, have a look at the log which accompanies the error message, and see what line is referred, and to which command.

Here is the program

*WILD* guess, but do you have all of the required headers at the start of each code file?
If the code will compile with another compiler then that compiler may not need an include file that the C18 compiler does.
Susan

 

[bethel]

Yes I did put the header and other necessary files in place. I tried compiling a smaller code and it worked. Though it's my first time using c18 compiler

This question is for guessing what error is this ? If you are new in programming, have a look at the log which accompanies the error message, and see what line is referred, and to which command.

Yes I have it's actually refering to line two and if I comment out line two, line 6 to 18 becomes the challenge.

 

[FvM]

You are trying to compile a code written for mikroC with C18. That doesn't work. The mikroC specific C extension have to be replaced by C standard compatible constructs understood by C18. Review the C18 manual how SFR accesses (e.g. to port bits) can be coded.

 

[betwixt]

'at' and 'sbit' are not part of the C language, they are part of MicroC but I don't think any other compiler will understand them.

instead of "sbit LCD_RS at LATC4_bit;" use "#define LCD_RS LATC,4;"

instead of "char keypadPort at PORTB;" try "#define keypadport PORTB". I do not use MicroC so it may be necessary to further qualify the 'char' type for keypadport.

Brian.

 

[FvM]

Microchip compilers have already structures with port bit definitions in their processor specific include files. Best way is to understand the intended syntax, e.g. by studying example projects shipped with the compiler or from Microchip application library.

 

[bethel]

I have corrected the syntax as advised by betwixt, those lines are fine now the challenge lies on line 35,36,37....... Attached here is the error message I now get from the c18 compiler.

There are HD44780 internal MikroC driver are used. You have to attach it as external library if you with to use it.

 

[betwixt]

"has not been defined" is the clue. The listed names are either not the standard Microchip register names or are commands to the LCD.
Go through the list and pick out the lines ending with that message then somewhere near the other 'define' lines, add your own definitions in the same way as you did to clear the earlier errors.

The basic problem is MikroC uses it's own non-standard additions to the C language which makes any programs written in it unrecognizable to other compilers. However, the main commands should still be the same if you #define the missing names. Almost certainly the _LCD_ defines are just the command numbers to send to the LCD to perform the function.

I'm not sure if you can add the MikroC LCD library to Microchip code. You can add most libraries but for the reasons already mentioned, it may not work.

Ignore the 'WARNING' near the top, it's just saying you are still in the free trial period before the optimizations are turned off and you have to buy a license to restore them.

Brian.

 

[Easyrider83]

I believe he able to find HD44780 library himself. May be the most popular topic in whole internet after mr.Putin offcause.

 

[bethel]

I have tried both solutions given above by betwixt and easyrider83 to fix the error but haven't succeeded yet. please I'd appreciate if you give me a little example on how to resolve the issue. am quite a novice in coding programs

 

[betwixt]

Replacing the pin definitions with #define should fix most of the problems.

The "...function without prototype" errors are telling you a function is called that doesn't seem to exist or is present more than once in different forms. Because you have since recompiled, the original error report is now out of date so it doesn't help us any longer, you need to post a new one.

I would guess the remaining issues are to do with "LCD_" instructions which are calls to a pre-built MikroC library routine. There is no direct equivalent in MCC18 but they can be written in just a few lines of code. Probably the easiest way to do it is to look at the code produced by MikroC and rewrite it as a new function in your program, otherwise look at the data sheet for the HD44780 which tells you exactly what to do. LCD drivers are very simple, all the hard work is done on the LCD itself.

Brian.
