Update 2/24/2023
I got some PCB and made my 100% wire-wrap “carrier” board for the ESP32 and DXL MKR shield - all the wire-wrappings are hidden beneath the PCB:
And interestingly, no more “128” Packet Error Message >> must have been due to some mechanical connection issues with my first wire-wrap solution.
So we found that although the D2A Library had never been written for Dual Core Programming, but thanks to the good job of the FreeRTOS folks in writing the ESP32 Scheduler, Dual Core multitasking can now be done for D2A with the Feather ESP32 V2 board, at least, as I have not tested other ESP32 based boards yet.
