Hi Gary,

Even though PWM is 10 bits, the registers to control it are only 8 bits.
You write the highest 8 bits to CCPR1L and the lowest 2 bits squeeze into
bits 4 and 5 of CCP1CON. You already know about CCP1CON since you had to
set bits 2 and 3 to enable PWM, just remember not to clear them when you
are writing the low PWM bits. Usually what I do is SWAPF the pwm value,
then OR it with 0x0F, then write that to CCP1CON.

If you only need 8 bit PWM then don't worry about it and write straight to
CCPR1L and only write 8 bit values!

Cheerful regards,

Bob Blick
