The actual compiler scripts are now a project on their own: spl-splitter. The source files in src/ are still kept here for reference, but they might be removed later as they are not required anymore for compilation.

All of this might be moved to this location at a later stage of the project: hardware/tools/stm8/STM8S_StdPeriph_Driver

The script in tools/showdeps.sh lists the known CPU names defined in inc/stm8s.h. Some CPUs use identical libraries:

Supported peripherie for the different CPUs:

CPU |STM8S001|STM8S005 |STM8S007 |STM8S208 |STM8S903 | |STM8S003|STM8S105 |STM8S207 | | | Module |STM8S103|STM8AF626x|STM8AF62Ax |STM8AF52Ax| |STM8AF622x ------ |:-----:|:------: |:------: |:------: |:------: | stm8s_adc1.c|+ |+ | | |+ |+ stm8s_adc2.c| | |+ |+ | | stm8s_awu.c|+ |+ |+ |+ |+ |+ stm8s_beep.c|+ |+ |+ |+ |+ |+ stm8s_can.c| | | |+ | | stm8s_clk.c|+ |+ |+ |+ |+ |+ stm8s_exti.c|+ |+ |+ |+ |+ |+ stm8s_flash.c|+ |+ |+ |+ |+ |+ stm8s_gpio.c|+ |+ |+ |+ |+ |+ stm8s_i2c.c|+ |+ |+ |+ |+ |+ stm8s_itc.c|+ |+ |+ |+ |+ |+ stm8s_iwdg.c|+ |+ |+ |+ |+ |+ stm8s_rst.c|+ |+ |+ |+ |+ |+ stm8s_spi.c|+ |+ |+ |+ |+ |+ stm8s_tim1.c|+ |+ |+ |+ |+ |+ stm8s_tim2.c|+ |+ |+ |+ | | stm8s_tim3.c| |+ |+ |+ | | stm8s_tim4.c|+ |+ |+ |+ | | stm8s_tim5.c| | | | |+ |+ stm8s_tim6.c| | | | |+ |+ stm8s_uart1.c|+ | |+ |+ |+ | stm8s_uart2.c| |+ | | | | stm8s_uart3.c| | |+ |+ | | stm8s_uart4.c| | | | | |+ stm8s_wwdg.c|+ |+ |+ |+ |+ |+

The definitions for these two (uncommon) CPUs are flawed in the original versions of the SPL. The patch for inc/stm8s.h is now part of the STM8-SPL_SDCC_patch.

Some (maybe) useful leftovers. These code snipplets might be useful again later.

Unpack two libraries and compare the individual files: cmplib.sh

#!/bin/sh

rm -rf a b
mkdir a b
(cd a; ar x ../$1)
(cd b; ar x ../$2)
diff -r a b

DEPS=$(shell sdcc -mstm8 -Iinc -Isrc -D$(CPU) "-Wp-MM" -E inc/stm8s.h)
HFILES = $(subst inc/,,$(filter inc/stm8s_%.h,$(DEPS)))

$(info DEPS=$(DEPS))
$(info HFILES=$(HFILES))

(now use HFILES to generate list of C-files into LIBSOURCES)

If all source files are already split into single-function source files this could be used to compile only the modules needed for the current CPU:

# include all parts for every needed module in the LIBSOURCES list
find_files = $(wildcard $(module)-*)
SOURCES := $(foreach module,$(LIBSOURCES),$(find_files))
# if only the needed modules got split: This simple version is good enough
#SOURCES := $(wildcard stm8s*.c)

OBJECTS=$(SOURCES:.c=.o)
OBJECTS_LINK=$(SOURCES:.c=.rel)
EXECUTABLE=$(shell echo $(CPU)|tr '[:upper:]' '[:lower:]').lib

# test output
$(info LIBSCOMMON: $(LIBSCOMMON))
$(info LIBSOURCES: $(LIBSOURCES))
#$(info SOURCES: $(SOURCES))
$(info EXECUTABLE: $(EXECUTABLE))


# targets
nothing:

all: $(SOURCES) $(EXECUTABLE)
	echo $^

$(EXECUTABLE): $(OBJECTS)
	$(AR) $(LDFLAGS) $(EXECUTABLE) $(OBJECTS_LINK) 

.c.o:
	$(CC) $(CFLAGS) $< -o $@

clean: 
	rm -f *.lib *.rst *.rel *.lst *.ihx *.sym *.asm *.lk *.map
	rm -f $(EXECUTABLE)
