Use DEFER-able dummy BUSCTRL as the default #55

Closed TG9541 closed 2 years ago

TG9541 commented 2 years ago

The C0135 "4-Relay-Board" GPIOs were used as a default RS485 bus access. Implement a dummy bus access that can either be replaced in a "board configuration" or a default DEFER can be redirected with IS to a board specific routine.
