pic18f4685 to a DSPIC33FJ128GP708A Timer 1 Broke [Solved]

[David Pouzar]

Hi All: I just moved to DSPIC33FJ128GP708A and can not get my Timer1 to run. I have hooked the 32.768k xtal with two 22pf Caps (same circuit I have used on my PIC18 project) to pin 59 (SOSCI) and pin60 (SOSCO). Have set my FUSES as follows:

#include <33FJ128GP708A.h>
#device ICSP=1
#device ADC=12

//#FUSES FRC //FAST RC OSCILLATOR
#FUSES HS //HIGH SPEED CRYSTAL
#FUSES WDT //Watch Dog Timer
#FUSES WPRES32 //Watch Dog Timer PreScalar 1:32
#FUSES WPOSTS11 //Watch Dog Timer PostScalar 1:1024
#FUSES CKSFSM //Clock Switching is enabled, fail Safe clock monitor is enabled
#FUSES NOJTAG //JTAG disabled
#FUSES NOWDT //NO WATCHDOG TIMER
#FUSES NOPUT //NO POWER UP TIMER
#FUSES ICSP1 //FIRST SET OF PROGRAMMING PINS
#FUSES NODEBUG //NODEBUG WITH ICD
#FUSES NORBS //NO BOOT RAM DEFINED
#FUSES NOSSS //NO SECURE SEGMENT
#FUSES NOWRT //PROGRAM MEMORY NOT WRITE PROTECTED
#FUSES SOSC //SECONDARY OSC


put in my initialization:
setup_timer1(TMR_EXTERNAL|TMR_DIV_BY_1);

Main using
printf(sendlcddata," %04lx",get_timer1());

results are 0000 is always displayed

Ideas?

I need to change my
setup_timer1(TMR_EXTERNAL|TMR_DIV_BY_1);
to
setup_timer1(TMR_EXTERNAL_RTC|TMR_DIV_BY_1);

nice when I can solve my own issue!
