# There exist several targets which are by default empty and which can be

# before and after some main targets. They are:
#
# .build-pre: called before 'build' target
# .build-post: called after 'build' target
# .clean-pre: called before 'clean' target
# .clean-post: called after 'clean' target
# .clobber-pre: called before 'clobber' target

# .all-pre: called before 'all' target
# .all-post: called after 'all' target
# .help-pre: called before 'help' target
# .help-post: called after 'help' target
#
# Targets beginning with '.' are not intended to be called on their own.
#
# Main targets can be executed directly, and they are:
#
# build build a specific configuration
# clean remove built files from a configuration
# clobber remove all built files
# all build all configurations
# help print help mesage

# Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and

BACnet Stack - SourceForge.net
Build for MPLAB IDE
These are some settings that are important when building
the BACnet Stack using MPLAB IDE and MCC18 Compiler,
1. Add the files to the project that you need:
abort.c, apdu.c, bacapp.c, bacdcode.c, bacerror.c,
bacstr.c, crc.c, datetime.c, dcc.c, iam.c,
npdu.c, rd.c, reject.c, rp.c, whois.c, wp.c
From ports/picxx: isr.c, main.c, rs485.c, mstp.c, dlmstp.c
From demo/object/: device.c or dev_tiny.c
objects as needed: ai.c, ao.c, etc.
From demo/handler/: txbuf.c, h_dcc.c, h_rd.c, h_rp.c or h_rp_tiny.c
Additional handlers as needed: h_wp.c
2. Project->Options->Project
General Tab: Include Path:
C:\code\bacnet-stack\;C:\code\bacnet-stack\demo\handler\;C:\code\bacnet-stack\demo\object\;C:\code\bacnet-stack\ports\pic18f6720\
MPLAB C18 Tab: Memory Model:

Data: Large Data Model
Stack: Multi-bank Model
MPLAB C18 Tab: General: Macro Definitions:
PRINT_ENABLED=0
BACDL_MSTP=1
TSM_ENABLED=0
BIG_ENDIAN=0
3. The linker script must reserve some extra stack space.
//DATABANK NAME=gpr12 START=0xC00 END=0xCFF
