# Select host device
#
# Supported classic AVR: atmega16, atmega88/168/328p, atmega1280/2560, probably others
# Supported Logic Green devices: LGT8F328P/D, however, atmega328p must be set as target
# Supported AVR-0/1 devices (aka avrxmega3 architecture on gcc): all that have at least 512 KB RAM
#
TARGETMCU=atmega328p
# configuration macros
#
# NDEBUG -> if defined, disable debug output
#
# F_CPU=value -> declares at which speed the host device is running (defaults to 16000000, 16MHz)
#
# UPDI_BAUD=value -> sets UPDI baud rate. Maximum is 225000 (225 kbaud, default value). Minimum is F_CPU/200
#
# ARDUINO_AVR_LARDU_328E -> if defined, host device is a Logic Green LGT8F328P/D
#
# UPDI_IO_TYPE=value -> Selects bitbang UART for interfacing with the UPDI target device. Possible values are 1 and 2.
# Type 1 is deprecated, so use type 2 (default).
#
# UPDI_PORT=port_letter and UPDI_PIN=pin_number -> Select port and pin for UPDI interface to target.
# If using UPDI_IO_TYPE=1, these must be set to the OC0A timer output pin.
# If using UPDI_IO_TYPE=2, these can be any free I/O pin.
# If the target is the Mega328P, defaults to the OC0A pin (PD6). See "sys.h" file for more details.
#
# HOST_USART=USARTx -> Select USART to be used for serial communication with the host PC, for host devices that
# have more than one USART peripheral (tiny AVR-0/1 and mega AVR-0 only). Defaults to USART0.
#
# HOST_TX_PORT=port_letter and HOST_TX_PIN=pin_number -> Must correspond to port and pin where the Tx signal of HOST_USART
# is present (tiny AVR-0/1 and mega AVR-0 only). Defaults to PB2, which is the Tx pin for USART0 on many tiny AVR-0/1 chips.
