Translating from mcc18
PostPosted: Mon Nov 24, 2008 7:53 am     Reply with quote
Hi I have following code in mcc18:
Quote:

26. extern unsigned char convString [20]; // 20 bytes - string holder
27. extern unsigned char convChar; // 1 byte
28. extern unsigned int convInt; // 2 bytes - unsigned integer
35. extern unsigned long short convInt24; // 3 bytes - unsigned integer

Compiling with CCS I got following errors
Quote:

***Error 46
Line 26(32,33): Expecting an =
Line 27(30,31): Expecting an =
Line 28(30,31): Expecting an =
***Error 38
Line 35(22,27): This type can not be qualified with this qualifier
*** Error 48
Line 35(28,37): Expecting a (

Any ideas?

My mistake. Following Errors are to be discussed.

In source code:
Quote:

#FUSES ...
#use delay(clock=8000000)

#pragma udata //Error 7-Invalid Pre-Processor directive

rom const char version[] = "0_00"; //Error 27-Expression must evaluate to a constant
rom const char maj_ver = 0x00;
rom const char min_ver = 0x00;

#pragma code high_vector = 0x08 //Error 7-Invalid Pre-Processor directive
void interrupt_at_high_vector(void)
{
#asm
goto high_isr //jump to interrupt routine
#endasm
}

// High priority interrupt routine

#pragma code //Error 7-Invalid Pre-Processor

#pragma interrupt high_isr //Error 7-Invalid Pre-Processor

void high_isr (void)
{
code
}

#pragma code low_vector = 0x18 //Error 7-Invalid Pre-Processor
void interrupt_at_low_vector (void)
{
_asm
goto low_isr
_endasm
}

#pragma code //Error 7-Invalid Pre-Processor
#pragma interruptlow low_isr //Error 7-Invalid Pre-Processor
void low_isr (void)
{
code...
}


In header file:
Quote:

extern rom const char version[]; // Error46 - Expecting an =
extern rom const char maj_ver; // Error46 - Expecting an =
extern rom const char min_ver; // Error46 - Expecting an =

extern unsigned long short convInt24; //Error 38-This type can not be qualified with this qualifier
