Hello MarkT
I'm not sure to understand your design, don't know if the isolation is between the Mega8 and the DRV8711, or between the connector SV1 and the DRV8711.
Seems that the DRV8711 can be controlled by both the command coming through SV1 and from the Mega8. Certainly for test purpose only, is that correct?
I'm asking because I destroyed an Arduino board by making some tests with that device, and I would know if we can drive the DRV8711 directly by a processor, or is we need some isolation/protection.
Thanks for sharing.
