Hello all,

I am rather new to this list, so I hope my question does not seem to dumb to
you all, but here goes...

Is it possible to drive more than one PWM output at different duty cycles
from the one PWM output pin (CCP1) on the PIC16F877 ?  This would be to
control two Peltier devices from the one PIC.  If so, can anyone give me a
suggestion on how to do this - I am not very keen on "emulating" PWM on
another port pin as timing then becomes too critical a factor - or am I
wrong here too?  I am seriously running out of available port pins on the
PIC in my current project.  To get two fan speed sensors running, I have
gone to the trouble of NAND gating the two pulses into Timer1 using a port B
pin to switch the gate between the two inputs.  At the moment I am seriously
considering using two PICS joined by SSP to do the job, but that seems to be
massive overkill.  Any suggestions anyone ?

Regards
Ian McLean
