===============================================
Hexabitz is a new kind of electronic prototyping platforms with game-changing modularity and a hint of biomimicry. Hexabitz modules connect with each other using a novel edge-soldering system and allow you to build tidy, compact and completely re-configurable electronic boards. Learn more about Hexabitz here.

===============================================
1- Navigate to Compiled folder and load the appropriate HEX file using any firmware update method described here.
1- If you don't have uVision installed already, download Keil uVision MDK toolchain from here. Get your free license for STM32F0 MCUs!
2- Download or clone this repository source code and open the uVion projext in MDK-ARM folder (it has .uvprojx extension).
3- If you are loading a single module, simply compile the code and load it to module MCU via one of the firmware update methods explaind here.
4- If you are loading multiple modules of the same type (connected in an array) and you want them to have unique firmware, then manually modify the module ID in Options for Target >> C/C++ >> Preprocessor Symbols >> Define >> _module=x (where x is the module ID) and in Output >> Name of Executable. Recompile the project and load each module according to its ID. You can also create multiple targets as explained in the firmware update guide.
You can also compile using GCC on your favorite toolchain.
1- If code is loaded correctly, you should see one or few indicator LED blinks when you power-cycle.
2- Use RealTerm or any other terminal emulator with a USB-to-USRT cable to access the module CLI. Learn about using the CLI here.
3- Check available CLI commands by typing help or use the module factsheet. Make sure the factsheet BOS version number (at the footer) matches the source code version you have.
1- If your project follows portability guidelines, then just keep all files in the User folder and replace all other folders with the newer source code.
To preseve maximum code portability between projects, we advise you to:
1- Keep all your custom source and header files in the User folder.
2- Add your code to the FrontEndTask() in main.c and add other custom functions there including custom interrupt callbacks.
3- Add any external header files you want to include to the project.h file.
4- Add any topology header files to User folder and include them in project.h.
