# makefile for STM8S_StdPeriph_Lib and SDCC compiler
#
# Customized by MightyPork 1/2017
#
# usage:
#   1. if SDCC not in PATH set path -> CC_ROOT
#   2. set correct STM8 device -> DEVICE
#   3. set project paths -> PRJ_ROOT, PRJ_SRC_DIR, PRJ_INC_DIR
#   4. set SPL root path -> SPL_ROOT
#   5. include required SPL modules -> SPL_SOURCE
