# Run `make` to build the project as a .hex file.
# Run `make flash` to program the device.
#
# MPLAB X is required if using a PICkit 3 to program the device.
# This Makefile assumes it's installed in /Applications/microchip.

########## Project-specific definitions ##########

# Project name
OUT = bootloader

# Source files to assemble
ASM = bootloader.asm

# USB serial number for the device

# (use `make list-devices` if not known)

# The MDB-specific part number of the chip, used for programming with MDB
# (should be the actual PIC part number, e.g. PIC16LF1454)
MDB_DEVICE = PIC16F1454
