PIC87J50 and USB(SOLVED)
PostPosted: Mon May 30, 2011 4:01 am     Reply with quote
Forgot the VUSB connection!!!!
FUSES:
Code:

#include <18F87J50.h>
#device ICD=TRUE
#device adc=16

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES PLL12                     //Divide By 12(48MHz oscillator input)
#FUSES NOXINST                  //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES DEBUG                    //Debug mode for use with ICD
#FUSES NOCPUDIV
#FUSES NOPROTECT
#FUSES HSPLL
#FUSES NOXINST                  //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES NOFCMEN
#FUSES NOIESO
#FUSES WDT128                   //Watch Dog Timer uses 1:128 Postscale
#FUSES NOEASHFT
#FUSES MSSPMSK7

#use delay(clock=48000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=ID20)



Hello,

I had the CDC code running on a PIC18F4550.. and now I want to get it running at a PIC87J50...
But I am missing something....
I think I messed up the fuse settings... (PIC Wizard isn't helping much)
What I have:

Compiler version: 4.119
Fuses:
Code:

#include <18F87J50.h>
#device ICD=TRUE
#device adc=16

#FUSES ECPLL
#FUSES NOWDT                    //No Watch Dog Timer
#FUSES WDT128                   //Watch Dog Timer uses 1:128 Postscale
#FUSES PLL12                     //Divide By 12(48MHz oscillator input)
#FUSES NOCPUDIV
#FUSES NOXINST                  //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES DEBUG                    //Debug mode for use with ICD

#use delay(clock=48000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8,stream=ID20)


and in mine code I enable the PLLEN:

}


anybody any ideas?????

Is this solved?.
Thread title says so.

I have to ask 'why' you are using 48MHz?. Unless it is available elsewhere for some reason, you get less RF problems, and lower power consumption, running off a slower clock.
However with 48MHz, the combination you are trying to use is 'over complex'.
You have 48MHz, so don't need the PLL.

EC
FOSC2=1
PLLEN=0
FSEN=1
gives 48MHz to the USB.

Then CPUDIV1, and primary clock source enabled, gives 48MHz to the CPU.
You are unnecessarily taking 48MHz, dividing it by 12, multiplying by 24, and then dividing by 2. All extra power that is not needed.....


Best Wishes
Jody

@Ttelmah,

You are right... it is a overkill and not charming to do this, this way.

And I will change it like the way you sugest... but the problem was that I can't connect to the USB ... and that is solved.

Thanks for thinking with me.

Regards,
Jody
