Passive Radar platform using Stepper and Rotary encoder

My concept involves saving the position into a Direct Memory Access (DMA) so that each time the Python script issues a command, the Arduino retrieves the last position it was in.

do you mean a ROM or FRAM ? be careful ROMs have a limited write life - how often do you intend to save to it? if in any doubt use an FRAM
