Could anyone help please? I am trying to use both CCP1 and CCP2 to work as 
PWM generators. CCP1 works fine. I cannot get anything from CCP2.

I attach some simple code I wrote to test it out. It works OK in that  with 
my scope I see a square wave of the correct frequency on RC2, but RC1 
obstinately stays at zero.

Could someone please suggest what might be wrong, or how I might investigate 
further. I emphasis - PWM comes out of RC2, but not out of RC1.

<SNIPPED inc and CONFIG stuff - CCP1 PWM works, so should be OK>

main
; Clock speed is 40MHz
	banksel	PR2
	movlw	0xFF	; Freq approx 10KHz with prescaler 4
	movwf	PR2

; Make the CCP1 and CCP2 pins outputs
	banksel	TRISC
	bcf		TRISC,RC1
	bcf		TRISC,RC2

	; Set PWM duty cycle (50%)
	movlw	0x80
	banksel	CCPR1L
	movwf	CCPR1L
	banksel	CCPR2L
	movwf	CCPR2L

	; Configure the CCP modules for PWM.
	movlw	0xC		; LSB duty cycle bits 0
	banksel	CCP1CON
	movwf	CCP1CON
	banksel	CCP2CON
	movwf	CCP2CON

	; Set TMR2 prescaler to 4 and turn it on.
	movlw	0x05
	banksel T2CON
	movwf	T2CON

loop
	goto loop
