PCD: XT_PLL8 problem
PostPosted: Thu Jan 22, 2009 9:15 pm     Reply with quote
Hi all,

I'm trying to use the XT_PLL8 with a 10Hz crystal but the target (DSPIC30F4013) don't work. When i use #FUSES XT and delay clock = 10000000 it works fine.

c.v. = 4.057

Code:
#include <30F4013.h>
#device ICD=TRUE
#device adc=8

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES XT_PLL8                 //XT Crystal Oscillator mode with 16X PLL
#FUSES PR                       //Promiary Oscillator
#FUSES NOCKSFSM                 //Clock Switching is disabled, fail Safe clock monitor is disabled
#FUSES DEBUG                    //Debug mode for use with ICD
#FUSES BROWNOUT                 //Reset when brownout detected
#FUSES BORV27                   //Brownout reset at 2.7V
#FUSES LPOL_HIGH                //Low-Side Transistors Polarity is Active-High (PWM 0,2,4 and 6)
   //PWM module low side output pins have active high output polar
#FUSES HPOL_HIGH                //High-Side Transistors Polarity is Active-High (PWM 1,3,5 and 7)
   //PWM module high side output pins have active high output polarity
#FUSES NOPWMPIN                 //PWM outputs drive active state upon Reset
#FUSES MCLR                     //Master Clear pin enabled
#FUSES NOPROTECT                //Code not protected from reading
#FUSES NOWRT                    //Program memory not write protected
#FUSES DEBUG                    //Debug mode for use with ICD

#use delay(clock=80000000)
#use rs232(baud=9600,parity=N,xmit=PIN_F3,rcv=PIN_F2,bits=8,stream=pc)
//#use rs232(baud=9600,parity=N,xmit=PIN_B0,rcv=PIN_B0,bits=8)


Can anyone help me?

Thanks in advance

Maybe same problem?

I noticed that on the 30F6012A yesterday when I tried to compile with the XT x 16 PLL fuse, MPLAB said that the fuse is incorrect and wouldn't load it. I finally just gave in and used the XT setting

I can compile the code, but my application don't work.

Compiler Update
PostPosted: Mon Jan 26, 2009 2:48 pm     Reply with quote
Problem was fixed by updating to a newer version of the compiler. Apparently I had been using a relatively old version and when I saw the list of changes it made me cringe with all of the PCD updates.

hi,
what version you use now? I use v4.084 and still have problems with oscillator configuration
