CCS Compiler and DsPIC
PostPosted: Sun Dec 06, 2009 6:00 pm     Reply with quote
Hi,

I have some problems with PCWHD and DsPIC30F3012. If the supply is +5V it works fine, but it the supply is +3.3V it does not work. It is a simple code, I think the problem is with the fuses...

If someone could help, thanks!
Code:

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES FRC_PLL4               //Primary Oscillator with PLL
#FUSES NOCKSFSM                 //Clock Switching is disabled, fail Safe clock monitor is disabled
#FUSES WPSB1                   //Watch Dog Timer PreScalar B 1:1
#FUSES WPSA1                  //Watch Dog Timer PreScalar A 1:1
#FUSES PUT4                    //Power On Reset Timer value 4ms
#FUSES NOBROWNOUT               //No Brownout reset
#FUSES BORV20                   //Brownout reset at 2.0V
#FUSES LPOL_HIGH                //Low-Side Transistors Polarity is Active-High (PWM 0,2,4 and 6)
#FUSES HPOL_HIGH                //High-Side Transistors Polarity is Active-High (PWM 1,3,5 and 7)
#FUSES NOPWMPIN                 //PWM outputs drive active state upon Reset
#FUSES NOMCLR                   //Master Clear pin used for I/O
#FUSES NOPROTECT                //Code not protected from reading
#FUSES NOWRT                    //Program memory not write protected
#FUSES NODEBUG                  //No Debug mode for ICD
#FUSES NOCOE                    //Device will reset into operational mode
//#FUSES ICS0                     //ICD communication channel 0
#FUSES RESERVED                 //Used to set the reserved FUSE bits

This is more of a Microchip forum question.
http://www.microchip.com/forums/search.aspx

Search the "dsPIC30F Topics" forum over there for this:
Quote:
5v 3.3v


Then you get threads like this, which are directly about the topic:
