# Basic Configuration
################################################################################

# Type of ModusToolbox Makefile Options include:
#
# COMBINED    -- Top Level Makefile usually for single standalone application
# APPLICATION -- Top Level Makefile usually for multi project application
# PROJECT     -- Project Makefile under Application
#
MTB_TYPE=COMBINED

# Target board/hardware (BSP).
# To change the target, it is recommended to use the Library manager 
# ('make modlibs' from command line), which will also update Eclipse IDE launch 
# configurations. If TARGET is manually edited, ensure TARGET_<BSP>.mtb with a 
# valid URL exists in the application, run 'make getlibs' to fetch BSP contents
# and update or regenerate launch configurations for your IDE.
TARGET=CYW920829-VR

# Name of application (used to derive name of final linked file).
# 
# If APPNAME is edited, ensure to update or regenerate launch 
# configurations for your IDE.
APPNAME=mtb-example-btstack-freertos-cyw20829-voice-remote

# Name of toolchain to use. Options include:
#
# GCC_ARM -- GCC provided with ModusToolbox software
# ARM     -- ARM Compiler (must be installed separately)
# IAR     -- IAR Compiler (must be installed separately)
#
# See also: CY_COMPILER_PATH below
TOOLCHAIN=GCC_ARM

# Default build configuration. Options include:
#
# Debug   -- build with minimal optimizations, focus on debugging.
# Release -- build with full optimizations
# Custom -- build with custom configuration, set the optimization flag in CFLAGS
# 
# If CONFIG is manually edited, ensure to update or regenerate launch configurations 
# for your IDE.
CONFIG=Custom

# If set to "true" or "1", display full command-lines when building.
