# 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).
