18F2550 and Blink Led

Hello mackrackit,

I don't know how pbp intalled there... i've intalled it a long time ago.

I'm looking at the assembler code, and it loops at:

CLRWDT --> Clear WTD
BTFSS PIR1,RCIF,A --> Check if Receiving bits... but i don't have nothing in my code...
BRA-3 --> Goto the CLRWDT again

anyone understand it??

Thanks,
Nuno

Another thing is in ASM file (after compile), it starts with:

#define CODE_SIZE 8
#define MCS_STEP 73H
#define MCS_DUMP 64H
#define MCS_HANDSHAKE 68H
#define MCS_RESET 72H
#define MCS_WRITE 77H
#define HSER_TXSTA 36
#define HSER_SPBRG

In my program, i don't define nothing of this...

Anyone understand it??

Thanks,
Nuno

I think the best thing to do is un-install everything (PBP, MCS, MPLAB) and start over.

MCS_STEP, MCS_DUMP, MCS_HANDSHAKE etc. come from the ICD (In-Circuit Debugger) in MicroCode Studio.

They only get added when you click the "ICD Compile Program" button.

When you compile a program for ICD, it will not run unless you are set up to use the ICD. (Serial connection to the PC).

If you use the normal "Compile Program" or just "Compile" buttons, the program will probably run better.

If you do not see a "Compile Program" or "Compile" button, right click on the toolbar and check the "Compile and Program" option.
You can turn off the ICD toolbar so you don't get confused in the future.

Hello,

What a silly mistake... You are wright Darrel, i'm compiling always with the ICD Compile...

Thanks for your help, it's solved.

Thanks,
Nuno

I'm trying to just compile the code below:

' PIC18F2550 
 DEFINE OSC 8 
 ADCON1 = %00001111
 CMCON = 7
 OSCCON = %01110000
 TRISB = %00000000
 START

 LATB.2 = 1
 PAUSE 250
 LATB.2 = 0
 PAUSE 250
 GOTO START

It gives Block overflow for #ENDCONFIG.

MCU is 18F2550

What might be the reason?

START label missing colon?
