Hwpw

[richard]

a pic18f26k22 can have 5 different pwm streams with 3 different frequencies all with individual duty cycles, old clunker chips like 16f876a are much less capable of course

here is 3 streams 3 frequencies
i find the hpwm command pretty inflexible and seldom use it [the clock defines are not correct in mho] , pwm is not difficult to setup manually

I ran your program and according to the scope they all are running the same freq. with different pulse width

I ran your program and according to the scope they all are running the same freq. with different pulse width

not really they all are running the same pulse width with different freq.

[l_gaminde]

Well, I don't know what to say. I get all the same frequency with different pulse width.
Even the program shows different pulse width.
I even went back to the pick basic plus and i'm running for with four different timers, and they all run the same frequency, and if you set it for a different frequency, they shut down pulse width, I can control

[richard]

Even the program shows different pulse width.

what do you mean ,that makes little sense

Well, I don't know what to say. I get all the same frequency with different pulse width.

my code works perfectly on the simulator and the actual hardware
post your code and schematic .

[l_gaminde]

I ran the code that you posted.

[l_gaminde]

Walking and talking on the phone does not work well.
I ran your program my scope has measure function all 3 channels showed the same frequency. But the duty cycle was the only difference. I used pbp setting ccp1, ccp2, ccp3 and ccp5 port c1, c2, and port b0, b5 there is also no control of individual frequency only duty cycle
