Thank you for your succinct response. It gives me some good ideas on how to implement dynamic braking and reversing. Back to the original discussion:
My original thought was to use a low-pass filter -> Regulated Voltage Booster but was directed to a DAC by an EE friend. (I was planning on using this circuit: http://playground.arduino.cc/Main/RegulatedPositiveVoltageBooster but he suggested using a dac and power supply to do the same thing without having to build the circuit myself). Adafruit sells a 0-5v PWM to analog converter breakout board, which I’m not opposed to, but would like the full range of 0-10v. Perhaps there’s a way to wire both boards to get the voltages I need?
TI has a white paper on PWM to Analog here: http://www.ti.com/lit/an/spraa88a/spraa88a.pdf
Which calls for usage of a DAC and lead me to believe using a DAC was a more appropriate route for my needs when coupled with the suggestion of my EE friend. Perhaps not? Ideally, I would like to minimize the number of extraneous circuits and wire runs (TinyG can’t output a 0-10v analog signal, right? :lol:)
