Import("env")
# Marlin has `RX_BUFFER_SIZE` and `TX_BUFFER_SIZE` to configure the
# buffer size for receiving and transmitting data respectively.
# Stm32duino uses another set of defines for the same purpose,
# so we get the values from the Marlin configuration and set
# them in `SERIAL_RX_BUFFER_SIZE` and `SERIAL_TX_BUFFER_SIZE`.
# It is not possible to change the values at runtime, they must
# be set with build flags.
#
# The script will set the value as the default one (64 bytes)
# or the user-configured one, whichever is higher.
