Need advice on project

anita1984

I have been doing a lot of reading and playing with sample codes( Spin language), but I’m missing something.
I believe the code I need will only be a dozens lines, so I keep reading and trying.The first step on my project is to control the speed of a motor( in Propeller Assembly language ) from 1 up to 4KHz and duty cycle 50%.I don't know in this case what is better to choose CTRMODE : %0001X for clock generation or CTRMODE : %0010X NCO ????
NB: i don't need to generate a PWM signal.
Thank you in Advance

You might get quicker answers with a more descriptive title for your post and posting in the propeller forum. That's my advice.

See the PWM section in the Counter Modules and Circuit Applications PE Kit Lab for a Spin prototype.
