mplab 8.90 (debug mode) & ccs 4.140 & pic18f25k50 (3.3v/16 mhz internal), debugger=mplab sim
when animate the main.c and arrive at puts() function when i press F8 appear the header file of pic18f25k50 and the pointer stay on the #device PIC18F25K50 (first line of the file header), i press 2/3 times F8 and the color of the pointer little change, but debug not continue. is this normal?
thanks |

Are running the program with an ICD-type hardware debugger (ICD2,
ICD3, ICD-U40, etc) on a hardware board ? Or, are you running the
program in MPLAB Simulator ? MPSIM doesn't use a board.
I ask this because your post is somewhat unclear. You mention MPSIM,
but then you give us details about your Vdd voltage.
Also, post a small test program that shows the problem. Here's an example:
| Code: |
#include <18F4520.h>
#fuses INTRC_IO, NOWDT, PUT
#use delay(clock=4M)
#use rs232(baud=9600, UART1, ERRORS)
//=================================
void main()
{
puts("Hello World\n\r");
while(1);
} |

I've seen that when watchdog is enabled, and as soon as it goes to print the watchdog triggers a restart.....

| Code: |
#include <18F25K50.h>
#device adc=16
#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES INTRC_IO //Internal RC Osc, no CLKOUT
#FUSES NOBROWNOUT //No brownout reset
#FUSES BORV28 //Brownout reset at 2.8V
#FUSES WDT_NOSL //Watch Dog Timer, disabled during SLEEP
#FUSES NOPBADEN //PORTB pins are configured as digital I/O on RESET
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
//#DEVICE ICD=TRUE
#use delay(clock=16M)
#use rs232(baud=19200,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=SERIALE)
#USE SPI (MASTER, SPI1, MODE=0, BITS=8)//, STREAM=SPISTREAM)
#use fast_io(c)
#use fast_io(b)
#use fast_io(a)
//=================================
void main()
{
puts("Hello World\n\r");
while(1);
}

with this code when i arrive to puts(), appear window of the 18f25k50.h file and the pointer stay on the #device PIC18F25K50 line, and nothing happen, if i fress many times F8, if i make RUN command the program goes to the while(1) line.
this happen with MPLAB SIM, i not have tryed with pickit3, but i think happen the same.
with this code i not see assembly windows.
I write voltage becouse i read the reccomandation on post for forum, so , i write  |

Try a more simple program. Compile this program, shutdown MPLAB,
then re-start MPLAB. Then press F8 and hold down the key.
It should display: Hello World
Make sure you have UART1 setup to run, in the Debugger / Settings menu.
Also make sure that 18F25K50 is selected in the Configure / Select Device menu.
| Code: |
#include <18F25K50.h>
#fuses INTRC_IO, NOWDT
#use delay(clock=4M)
#use rs232(baud=9600, UART1, ERRORS)
//=================================
void main()
{
puts("Hello World\n\r");
while(1);
