# LongFi Arduino
|
||||
|
||||
## Installing the MCCI LMIC Library
|
||||
|
||||
From the Arduino IDE, open the Library Manager (Sketch->Include Library->Manage Libraries). In the search box, type MCCI and select the MCCI LoRaWAN LMIC library should be the first result.
|
||||
|
||||
|
||||
|
||||
## Board Support
|
||||
|
||||
### B-L072Z-LRWAN1 - ST STM32L0 Discovery kit
|
||||
Install board support package, find instructions [here](https://github.com/stm32duino/Arduino_Core_STM32#getting-started).
|
||||
|
||||
Arduino IDE:
|
||||
1. Select Tools -> Board: -> Discovery
|
||||
2. Select Tools -> Board part number: -> Discovery L072Z-LRWAN1
|
||||
# ST B-L072Z-LRWAN1 - Basic LongFi Example
|
||||
|
||||

|
||||
|
||||
## Required Board Support & Library
|
||||
|
||||
### Arduino Core for STM32L0
|
||||
Arduino IDE:
|
||||
1. Navigate to (File > Preferences)
|
||||
Find the section at the bottom called Additional Boards Manager URLs:
|
||||
2. Add the URL below to the list and click ok to close the preferences.
|
||||
```
|
||||
https://grumpyoldpizza.github.io/ArduinoCore-stm32l0/package_stm32l0_boards_index.json
|
||||
```
|
||||
|
||||
|
||||
3. Open Boards Manager: Select Tools > Board: > Boards Manager...
|
||||
4. Search for "Tlera Corp STM32L0 Boards"
|
||||
5. Select the newest version and install.
|
||||
|
||||
|
||||
## Programming (Uploading Method):
|
||||
|
||||
### B-L072Z-LRWAN1 - ST STM32L0 Discovery kit
|
||||
|
||||
#### STM32CubeProgrammer(SWD)
|
||||
Will use onboard ST-Link(Flasher/Debugger) to upload sketch.
|
||||
Download and Install required utility from ST [here](https://www.st.com/en/development-tools/stm32cubeprog.html).
|
||||
|
||||
Arduino IDE:
|
||||
Select Tools -> Upload Method -> STM32CubeProgrammer(SWD)
|
||||
Arduino IDE:
|
||||
1. Select Board: Tools > Board: > B-L072Z-LRWAN1
|
||||
2. Select Port: Tools > Port > COM# or /dev/ttyACM#(B-L072Z-LRWAN1)
|
||||
3. Upload Sketch: Select > Upload
