mplab problems with .COF files

[tipoldo]

Hi to all,
i'm using CCS to program in C, and MPLABSIM to debug my programs. Normally it runs well, but sometimes the MPLABSIM loses the relation between the ASM line and de C line. It happens normally in the modules files. Looking the dissambler file it show a full function implemetation code, and next the corresponding ASM code (together), but it shoud show the ASM code of each C line code.

For example:

BOOLEAN integrarActualizarEntrada(struct S_estadoActualEntrada *estadoActualEntrada,
15: BOOLEAN entradaPin)
16: {
17:
18: //Integramos la entrada
19:
20: if (entradaPin)
21: {
22: estadoActualEntrada->analogica += MOD_I_INT_K_INCREMENTO;
23: //Chequeamos que no nos hemos pasado de 255
24: if (BIT_C)
25: {
26: estadoActualEntrada->analogica = 255;
27: }
28: }
29: else
30: {
31:
32: estadoActualEntrada->analogica -= MOD_I_INT_K_DECREMENTO;
33: //Chequeamos que no hayamos restado menos que 0
34: if (!BIT_C) //En la resta el carry = !borrow, es decir, la l�gica es al reves, si se pasa se pone a 0
35: //si no se pasa se pone a 1. Mirar Datasheet.
36: {
37: estadoActualEntrada->analogica = 0;
38: }
39:
40: }
41:
42: //Devolvemos el valor de la entrada en digital seg�n el criterio.
43: //Tiene una histeresis en el cambio de valor:
44:
45: if (estadoActualEntrada->analogica > MOD_I_INT_LIMITE_ON)
46: {
47: estadoActualEntrada->digital = 1;
48: }
49: else if (estadoActualEntrada->analogica < MOD_I_INT_LIMITE_OFF)
50: {
51: estadoActualEntrada->digital = 0;
52: }
53:
54: return estadoActualEntrada->digital; //Si no esta ni por encima ni por debajo no modificamos
55:
56: }

Somebody has had a similar problem?

Another problem is that in the wach tool from MPLAB, it show 8 bit pointers like 16 bit pointers?? why?? how can I change that??

Thank's and reggards from Spain!!

In the Watch window, right-click with your mouse on the symbol name.
In the pop-up menu, select Properties. There is a drop down box
to set the size to 8, 16, 24 or 32 bits.

If there's a problem with the .COF file, then report it to CCS support.

Hello "PCM programmer",
First, thank you for your answer.

- Also, about the problem of the 8 bit pointer, I knowed this drop down box in the properties window, but the problem is that when I add a pointer variable with the "Add symbol" from the watch tool. In this case, the drop down box from the properties of the pointer variable is disable, and always shows this pointer variable with 16 bit (and my pic has only 8 ). I think that is a MPLAB problem, and therefor perhaps this is not the correct forum.

- About the cod file problem, I have got still this problem. Then, I will send a sample code to CCS support. I you want this sample file, say to me pleas and will I add a copy to you. My email is [email protected].

Best Regards and sorry for my bad english!!

Sorry, I have wrong wrotten. It has to be .cof file. Thank you for all.

Up to now, what I have seem is that, when I finish the main file with the includes of the .c file of the modules (due CCS hasn't a linker), it have to finish with a EOL. In the case that I don't put this EOL, the compiler doesn't show any errors, but the .cof doesn't include the code including in the corresponding .c file.
