Hello all,

I think i have a problem ... do i ?

I would like to generate 2 different PWM signals using the PIC16C73A.

signal 1 : fixed frequency and variable duty cycle on CCP2
signal 2 : variable frequency and fixed duty cycle on CCP1

duty cycle register can be programmed with 10/8 bit for each CCP

BUT ! for the frequency there is only the PR2 register.

PWM uses only Timer2 so to generate two different signals i need 2
Timers.

I would like to use only hardware PWM so no software code is need to
drive the PWM ports
once they are started up. Only when an interrupt is received on the IIC
port the frequency or
duty cycle is changed.

I hope i am wrong !


Thanks in advance for your replies and greetings from Europe !
