SteptoVoltConverter.jpg is found in Files - Stepper Driver
Schematics.
In roughly the center of the schematic, there is a 100k resistor
coming out of pin 3 of the chip. This 100K resistor is going into
another 100k resistor - should this one be a trim pot? and if so,
how is it used in practice?
If anyone has built this circuit, I would like to hear how it works
for you. I am looking to control a DC motor (Which the driver uses
0 - 10 VDC) as it's speed input.
Thanks
