I've got HWPWM 1 (RC2/CCP1) feeding into TMR1 counter input (RC0/T1CKI).
I want the PWM set at 1KHz @ 50%...

I've programmed the PIC (16F877A I/P) and it's running but TMR1 is not incrementing... A standard Digital multimeter reports a solid 5 volts on RC2/CCP1...

When i simulate the software in oshonsoft PIC simulator i set up an simulated signal generator to RC0/T1CKI tmr1 input and i can see TMR1L and TMR1H registers increment... However, HWPWM1 goes high and stays high... I've left it running for an hour on my PC (>65,000uS simulation time)...

The following code is used to initialise my PIC...

Code:
Define  CONF_WORD = 	$3F3A
include "bs1defs.bas"
Define  OSC				24				' Set clock speed
DEFINE  SER2_BITS		8				' Ser2 number of data bits
SEROUT2 PORTB.5,16390,[10,13,10,13]
SEROUT2 PORTB.5,16390,["INITIALISING",10,13]
Define  ADC_BITS        10     			' Set number of bits in result
Define  ADC_SAMPLEUS    100    			' Set sampling time in uS
ADCON0.6 = 1							' ADC clock set to Fosc/64
ADCON0.7 = 1							' ADC clock set to Fosc/64
ADCON1.6 = 0							' ADC clock set to Fosc/64
INTCON = 0								' Disable all interupts
'RCSTA = %10010000						' Enable serial port and continuous receive
'TXSTA = %00100100						' Enable transmit and asynchronous mode with BRGH 1
'SPBRG = 20								' Set baud rate to 57600 with 20mhz clock (BRGH = 1)

###A load of variables go here###

TRISE = %00000111							' Set PortE to all inputs
TRISD = %00000000							' Set PortD to all outputs
TRISC = %00000001							' Set PortC to all outputs
TRISB = %00000000							' Set PortB to all outputs
TRISA = %11111111	 						' Set PORTA to all input
ADCON1 = 0 									' PORTA is analog

PORTB = 0
PORTC = 0
PORTD = 0

gosub TMR1setup
HPWM 1,127,1000 
SEROUT2 PORTB.5,16390,["INITIALISED",10,13]

TMR1setup:
TMR1L = 0							' reset TMR1 low to 0
TMR1H = 0							' reset TMR1 high to 0
PIE1.0 = 0							' Disable TMR1 interupt (double check)
T1CON.5 = 0 						' Setup TMR1 timings 1:1
T1CON.4 = 0							' Setup TMR1 timings 1:1
T1CON.3 = 1							' Oscillator is on
T1CON.2 = 1							' Do not synchronize external clock input
T1CON.1 = 1							' External clock from pin RC0
T1CON.0 = 1							' Enables Timer1
return
so the HW PWM is set with
Code:
HPWM 1,127,1000
and i've checked the syntax.

Can anyone see whats wrong?

Thanks
