Hi Jim,

I haven't used the 16f1779 with PWM, but I do with a 16f18855. I expect=20
for PWM these are similar.
As you can see in the datasheet (TABLE 4) there is no default PWM output=20
pin. You need to assign one with PPS.
Not very complicated: RA3PPS =3D 0x1E; when you want the PWM signal on=20
RA3  (see table 12.2 and provided you follow example 12.1)

Good luck! Rob.
