LoRaWAN C library for MSP430 MCU

End Devices (Nodes) LMIC

Hello,

I need to find a LoRaWAN library for a MSP430 micro controller using RFM95W. I have only seen LMIC libraries for Arduino or Mbed laying around…

Anyone know any solution or workaround?

Thanks in advance!

I use that LoRaWAN implementation for our node which is msp430 based. It works like expected.

Hi thanks for your reply! Okay I thought that library was dependent on the listed hardware in the readme file. Which library files do you use?

I have my current c-code with my own implementation of SPI functions to other slaves gathering data, so I can’t really start from scratch. What would you suggest me to do?

Some info can be found in the porting guide. You have to provide some basic functions. And the only thing to change in the stack itself was the mcu-wakeup time - but that is not nessery with the current version (Now via SX1276GetBoardTcxoWakeupTime).

The makefile includes the stack:

SOURCES += $(RFDIR)/LORA/Semtech/src/radio/sx1276/sx1276.c
SOURCES += $(RFDIR)/LORA/Semtech/src/mac/LoRaMac.c
SOURCES += $(RFDIR)/LORA/Semtech/src/mac/LoRaMacCrypto.c
SOURCES += $(RFDIR)/LORA/Semtech/src/mac/region/Region.c
SOURCES += $(RFDIR)/LORA/Semtech/src/mac/region/RegionCommon.c
SOURCES += $(RFDIR)/LORA/Semtech/src/mac/region/RegionEU868.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/delay.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/fifo.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/gpio.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/timer.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/crypto/cmac.c
SOURCES += $(RFDIR)/LORA/Semtech/src/system/crypto/aes.c

I Added the compiler flag " -DREGION_EU868" to set the region.
The rest is just to glue it with the rest of your hardware/projekt (boards directory for examples).

I have done a rapid port of the “Arduino LMIC” library to Energia, which is the equivalent of Arduino IDE for TI launchpads boards, including some MSP430 based.

You can find it here : https://github.com/DeuxVis/energia-lmic

Can you provide further information about the modifications, I’m trying to build an MSP430 based node and I’m quite lost searching for libraries
