Position Pulse input on Slave unit

[SQ8CBU]

Hi , I decided to write this message because my previous attempts to configure and get help at https://groups.io/g/radioartisan have not worked. Below is my message from the discussion group:
I'm trying to configure equipment with Master - Arduino Mega (PC interface, display and buttons) and Slave - Arduino UNO or MEGA (pulse input and relays control).
I want to build configuration with only remote serial port communication between Master and Slave unit - optically isolated.
In my current configuration i can send command from Master to activate relay CW or CCW on Slave unit .Right now this command only activates port, but Slave unit isn't in "rotating" state and unit counts pulses without calculating angles.
Is it possible to modify programm ,so that Slave unit calculates angle from pulses and controls relays ?
Thanks for any suggestion.

This would be in line with this proposal #14 (comment) .
Extension of the number of the commands and split functions beetwen modules.
Is there a chance to implement such changes?
