Here is the magic here
|

1) AndreiKA has downloaded libtinyc from somewhere
|

2) AndreiKA has compiled libtinyc locally
|

3) AndreiKA has taken some of the .o object files and pasted those here
|

4) AndreiKA has added his custom libc_stub.c

libtinyc.a is the gcc library produced from all the above mentioned object files

todo: open question where is the official home of libtinyc

This is about wasting as little RAM as possible. Even complete libtinyc wastes some RAM.

rusEfi runs on MKE16F512 (alpha version as of July 2019)
|
||||
|
||||
rusEfi Kinetis implementation consists of three files/folders:
|
||||
firmware/config/boards/kinetis
|
||||
firmware/hw_layer/ports/kinetis
|
||||
firmware/hw_layer/trigger_input_comp.cpp
|
||||
|
||||
|
||||
Since MKE16F512 is the first not stm32 rusEfi implementation, AndreiKA has a lot of fun!
|
||||
Kinetis overrides are in
|
||||
firmware/config/boards/kinetis/rusefi_hw_enums.h overrides pins
|
||||
firmware/config/boards/kinetis/config/rusefi_config_kinetis.txt
|
||||
|
||||
todo:
|
||||
have rusefi_stm32_hw_enums.h
|
||||
have rusefi_kinetis_hw_enums.h
|
||||
move more generated files to 'generated' folder(s)
|
||||
maybe generated_stm32?
|
||||
|
||||
todo:
|
||||
move firmware/config/boards/kinetis/config/!gen_enum_to_string.bat somewhere else? merge with stm32?
|
||||
|
||||
At the moment we use internal RC generator. Open question if it's good enough.
