* stm32_settings_stub.cpp
|
|
*
|
|
* Standalone stub that wraps the real RadarSettings class.
|
|
* Reads a binary settings packet from a file (argv[1]),
|
|
* parses it using RadarSettings::parseFromUSB(), and prints
|
|
* all parsed field=value pairs to stdout.
|
|
*
|
|
* Compile: c++ -std=c++11 -o stm32_settings_stub stm32_settings_stub.cpp \
|
|
* ../../firmware/9_1_Microcontroller/9_1_1_C_Cpp_Libraries/RadarSettings.cpp \
|
|
* -I../../firmware/9_1_Microcontroller/9_1_1_C_Cpp_Libraries/
|
|
*
|
|
* Usage: ./stm32_settings_stub packet.bin
|
|
* Prints: field=value lines (one per field)
|
|
* Exit code: 0 if parse succeeded, 1 if failed
