# DroneCAN stack + libcanard transport.

# Each MCU family that wants the stack opts in from its own .mk file with

# one line:

# LIB_SUBMODULES += $(DRONECAN_LIB_DIR)
|
|
#
|
|
# When this file is sourced (after the MCU .mk has populated
|
|
# LIB_SUBMODULES) the presence of that path triggers the rest of the
|
|
# wiring: source list, size-optimised flags and include directory. MCUs
|
|
# that don't opt in never reference libcanard, so neither the external
|
|
# library nor the Betaflight-side glue is compiled for non-CAN targets.
