An Arduino is one solution. http://axis.unpy.net/01198594294 Another idea is to use PWM output and a comparator. This would need a hal compoenent to be written. The idea is that the PWM is converted to analogue voltage (with optical isolation this could even be mains voltage). A comparator chip then sets an input bit depending on whether the PWM voltage is over or under the voltage to be measured. A simple inc/dec or P controller adjusts the PWM duty cycle to track the measured voltage. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
