Technical support / Re:reversible counter
« on: July 21, 2008, 01:52:12 AM »
Thanks for your reply.
but  can I not then use one counter eg:C1 as reversible up/down counter.
My program is as follow:



  CtUp    C1
|--||---( Upctr)
  CtDn    C1
|--||---( Dnctr)

so that I can use ctup and ctDn to count up/down of Counter C1?

how do I compare the counter value with some value say '4'?
ie: how do I know that the counter has counted 4 which is not the set value

Thanks

Hi ;D
Thank you for your reply
I figure out that both pin 7 and 8 have no output.
I will replace the IRL530N.
Thanks again for your support.

Hi
Thanks for your fast reply.
I did tried 2kHz, but result is the same ie: no pwm output wave form and motor running at full speed.

Do I have to do some more things to initialise the pwm beside setpwm 1, 8500,20000?

Thank you very mush

Hi ;D
I try to use the pwm channel 1 (pin 7) to control the speed of my 24 volt dc motor.
I use function setpwm 1,8000,32000.
but when I measure the ouput of pin 7. I dont get the pwm waveform and my dc motor is running at full speed.
What should I do to control the speed of the 24v motor
