# Build instructions
This project uses the simple PlatformIO build system. You can use the IDE, but for brevity
in these instructions I describe use of their command line tool.
1. Purchase a suitable radio (see above)
2. Install [PlatformIO](https://platformio.org/platformio-ide)
3. Download this git repo and cd into it
4. Edit configuration.h and comment out *one* of the following two lines (depending on which board you are using):
```
// #define T_BEAM_V10
#define HELTEC_LORA32
```
5. Plug the radio into your USB port
6. Type "pio run -t upload" (This command will fetch dependencies, build the project and install it on the board via USB)
7. Platform IO also installs a very nice VisualStudio Code based IDE, see their [tutorial](https://docs.platformio.org/en/latest/tutorials/espressif32/arduino_debugging_unit_testing.html) if you'd like to use it

## Decoding stack traces
If you get a crash, you can decode the addresses from the `Backtrace:` line:
1. Save the `Backtrace: 0x....` line to a file, e.g., `backtrace.txt`.
2. Run `bin/exception_decoder.py backtrace.txt` (this uses symbols from the
last `firmware.elf`, so you must be running the same binary that's still in
your `.pio/build` directory).
