Convert BoostC to XC8

[Ferla]

Hello guys
You can help me in converting from FC4 BoostC to FC7 XC8.
I have a project created in FC4 with several icons in C code, now I would like to bring it to FC7 to make some changes.
After several nights of trying to find solutions by reading the XC8 manual and surfing the forum, ideas got confused.
I split by number.16 macro the code C to convert.Some are replicating.

Thank you

Hello,

The following conversions should hopefully help.

intcon.GIE = 0; -----> INTCONbits.GIE = 0;
intcon.GIE = 1; -----> INTCONbits.GIE = 1;
intcon.RBIF = 0; -----> INTCONbits.RBIF = 0;
intcon.RBIF = 1; -----> INTCONbits.RBIF = 1;
clear_bit(intcon, RBIF); -----> INTCONbits.RBIF = 0;

INTCON.RBIE = 1; -----> INTCONbits.RBIE = 1;
INTCON2.RBIP = 1; -----> INTCON2bits.RBIP = 1;
INTCON2.RBPU = 1; -----> INTCON2bits.RBPU = 1;
RCON.IPEN = 0; -----> RCONbits.IPEN = 0;

wreg= portb; -----> WREG = PORTB;

These are ok.
PORTB = 0b00001110;
TRISB = 0b11110001;

Assembler statements now should look like this.

asm("CLRF _PORTA");

Or this ...

Code: Select all

#asm
	CLRF PORTA
	GOTO 0
#endasm

Beny / LeighM ....... not even Superman and fast as you when you need it.
Thanks tonight I try to let you know.

The assembler command sleep can be replaced with this C command.

Code: Select all

Sleep();

The assembler command reset can be replaced with this C command.

Code: Select all

RESET();

Guys I got stuck and I can not understand why the compiler from these mistakes...!!!

Hello,

Check your configuration settings inside the project options window. The extended CPU configuration setting is active but not supported by the compiler.

The other things seem to be warnings only.

Hi Benj
As you rightly advised, it was an active setup within the chip configuration.
Now you can compile perfectly but only if I remove the C code:
asm
{
bcf _porte,2
}

Try the formatting types you advise but nothing.
You can kindly tell me how to convert it correctly for XC8.
Thanks.

Hello,

You can probably replace that code with the following.

asm("BCF _PORTB, 2");

Many thanks for your collaboration Benj
Fixed I did not put space between the 2 and the comma.
