How i can define flash blocks values in my structure variable named "const zone_t polygon[cantidad_poligonos_declarados]" ? It looks like you can't see the forest for the trees :) If you define a pointer to flash block like: const zone_t * ptr = (const zone_t *)0xC000; and also take advantage of fu...

Code: Select all

zone_t tmp = *(const zone_t *)0xCCCC;

// access tmp members here

or if you wish to save RAM, just use a pointer to struct:

Code: Select all

const zone_t * ptr = (const zone_t *)0xCCCC;

// vertices: ptr->vertices
// lat: ptr->lat[0]
// etc...

Spherical law of cosines formula for distance calculation is not well-conditioned for single precision floats. Use haversine formula.

Code: Select all

#include "built_in.h"

unsigned short aux1, aux2, aux3, aux4;
float y = 3.5;

aux1 = Lo(y);
aux2 = Hi(y);
aux3 = Higher(y);
aux4 = Highest(y);

NOTE: You don't even need aux variables.

Usually I declare extern variables in a header file! It doesn't matter where you declare them. Only source files are compiled. The content of header files is just included in them by the preprocessor. Preprocessor is not an integral part of a C compiler. In fact, the preprocessor used by mC is not ...

Is there any data 2 bytes? like a short type in c++

Of course:
int - 2-byte signed integer
unsigned int - 2-byte unsigned integer
long - 4-byte signed integer
unsigned long - 4-byte unsigned integer

In mikroC:
char is 1-byte unsigned integer
short is 1-byte signed integer
unsigned short is equivalent to char

I'll answer your question with another question related to your example. Imagine you have a third source file with an extern defined as: extern unsigned char _g_Cnt; Q: Which variable does extern refer to? The one from _UCT.c or the one from _DCT.c? Declaring a global object as static would be the e...

You can if you add static storage class specifier.

Try:

Code: Select all

#pragma funcall loadTask func1

That can happen only if the project didn't compile and mikroProg uses old hex file or you specified wrong search paths in project settings (Project -> Edit Search Paths...). I suggest you to try the following: 1. Open your *.h file and make the change 2. Delete everything from project folder except ...

The problem is that when I do this without opening the MikroC gui but instead I use the DOS command lines to download my program, the new User.h file(the last one I copied into the PIC32 directory) is not seen. It still keeps the information of the old User.h file WHICH I DELETED!!!! I might be wro...

After compilation just copy-paste the first line from messages window. It contains the command-line call to compiler.
