Phidgets 8/8/8 pwm output question
Phidgets 8/8/8 pwm output question
Hi guys,
How can I make a PWM output from a phidgets 8/8/8? I want to create a PWM output to feed my motor controller. I am trying to do this without having to upgrade (Yet), and so my only output is the 8/8/8.
Ultimately, I need the 8/8/8 to output a RC servo pulse.
Thanks for your input.

Re: Phidgets 8/8/8 pwm output question
Sorry no, the max output frequency of the 888 is too slow.
You will need a servo board, the good news is that there of lot's of these and some are really cheap. Pololu & Parallax make some good low cost versions that work with FlowStone:

Also if you want to be a geek you can also use the sound card to drive two servos with PWM!

Re: Phidgets 8/8/8 pwm output question
Is it possible to output a serial command from the phidgets board.
Re: Phidgets 8/8/8 pwm output question
Again I think your will find it too slow and the timing not accurate enough.
If you want serial then just get a USB - serial adapter!

I understand what you mean about speed. Got the motor controller running like a champ via USB-Serial adapter through an RS232-TTL level converter.
