# Building
|
|
## Prerequisites
|
|
The build system of this repository is based on Make. The `Makefile` is in the base of the repository. Please ensure you have `arduino-cli` installed before proceeding.
|
|
|
|
Firstly, figure out which MCU platform your supported board is based on. The table below can help you.
|
|
|
|
| Board name | Link | Transceiver | MCU | Description |
|

|
| Homebrew ESP32 boards | | Any supported | ESP32 | This can be any board with an Adafruit Feather (or generic) ESP32 chip |
|
|
|
|
### ESP32
|
|
If your board is ESP32-based, please run `make prep-esp32` to install the required BSP and libraries for that target.
|
|
|
|
### nRF52
|
|
If your board is nRF52-based, please run `make prep-nrf` to install the required BSP and libraries for that target.
|
|
|
|
## Compiling
|
|
Next, you need to find the name of the target for your board. Please reference the table below to do so:
|
|
| Board name | Target |
|
|
| :--- | :---: |
|
|
| Handheld v2.x RNodes | `rnode_ng_20` |
|
|
| RAK4631 | `rak4631` |
|
|
| LilyGO T-BEAM v1.1 | `tbeam` |
|
|
| LilyGO T-BEAM v1.1 (SX1262) | `tbeam_sx126x` |
|
|
| LilyGO LoRa32 v1.0 | `lora32_v10` |
|
|
| LilyGO LoRa32 v2.0 | `lora32_v20` |
|
|
| LilyGO LoRa32 v2.1 | `lora32_v21` |
|
|
| Heltec LoRa32 v2 | `heltec32_v2` |
|
|
| Heltec LoRa32 v3 | `heltec32_v3` |
|
|
| Homebrew ESP32 boards | `genericesp32` |
|
|
|
|
After you've ascertained the target for the board simply run the following to compile for the board:
|
|
|
|
`make firmware-[target]`
|
|
|
|
Ensure you replace [target] with the target you selected. For example:
|
|
|
|
`make firmware-rak4631`
|
|
|
|
## Flashing
|
|
To flash the chosen board (if you have one), simply connect it to your computer over USB, and then run the following:
|
|
|
|
`make upload-[target]`
|
|
|
|
Ensure you replace [target] with the target you selected. For example:
|
|
|
|
`make upload-rak4631`
|
|
|
|
**Please note**, you must re-compile the firmware each time you make changes **before** you flash it, else you will just be flashing the previous version of the firmware without the new changes!
|
|
|
|
These commands can also be run as a one liner. For example:
|
|
|
|
`make firmware-[target] && make upload-[target]`
|
|
|
|
This is especially helpful when making continuous changes to the firmware and testing them out.
