speed debug icd-u64
PostPosted: Tue Dec 16, 2014 11:16 am     Reply with quote

Hello,

I'm using PCWHD version 5.019 with ICD-U64 and in my target there's a DSPIC33FJ256GP710. I've created a Project with "Project 24 Bit wizard". In my target I've an oscillator of 12 MHz, therefore I've configured:

Crystal clock speed: 12.000.000 Hz
CPU Clock speed: 80.000.000 Hz => 40 MIPS.

When I program in release mode the MCU runs at 80 MHz but when I program in debug mode in the debug Windows appears 7.47 MHz and I don`t know because run so slowly.

In debug mode isn't possible to run at 80 MHz?

I attached the code:
Code:

#include <33FJ256GP710.h>

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES CKSFSM                   //Clock Switching is enabled, fail Safe clock monitor is enabled
#FUSES NOJTAG                   //JTAG disabled
#FUSES PR_PLL
#FUSES HS
//#FUSES FRC_PLL



#device ICSP=3
#use delay(clock=80000000,crystal=12000000)

#define LED PIN_E5
#define DELAY 1000

void main()
{



   //Example blinking LED program
   while(true)
   {
      output_low(LED);
      delay_ms(DELAY);
      output_high(LED);
      delay_ms(DELAY);
   }

}

Thanks a lot.

David.

I have a 'niggling memory' that there was a limitation at about 70MHz on the original ICD U64. Try something like 60MHz and see if this then works.
