Hi,

HPWM is on pin 2 instead of pin 3 on my nano8 (in the data sheet it's supposed to be on pin3)
The other thing is I can use the code HPWM with any pin P0, P1, P2, P3 it will take the last duty cycle I write (even if it's on P0 for exemple) but only pin2 will have the HPWM?

Thanks

PS it's not a problem, I am just surprised

It appears the datasheet is wrong. P2 is the HPWM capable pin. There is only one CCP capable pin on the Nano 8. You can put any pin number you want in the HPWM command. If it isn't capable of HPWM it won't do anything.

I've let the document writer know to fix that right away. Sorry about the confusion.

Thanks for the info.
There is one more strange thing, if I enter :



I get the HPWM working on pin 2

If I enter :



I get 153 kHz on pin 2 where I should get 16 kHz as if the last HPWM command was the good one even if the wrong pin was enter?

Thanks

Chris

The simple solution is don't run HPWM using pin numbers that aren't valid.

In this case I expect the HPWM command is ignoring the pin number because it knows there is only one pin that can run HPWM on the Nano8 and just executes the period and duty on p2 no matter what pin you specified.

ok, I will
