How does the NAMote72 interface with Arduino?

I see that there are header pins, but where is the code to interface the NAMote72 and an Arduino?

Hi Mike,

Sorry for the delay on the response. There was an issue with the mbed server and my account, thus not being able to make edits from my dashboard. All is working now.

In regards to the Arduino headers on the NAMote72, basically they allow for interfacing to other mbed sensor shields and available GPIOs. Thus providing access to available GPIO, SPI and I2C interfaces from the standard Arduino headers. From the Port diagram for the NAMote72 the I2C pins are on D14 and D15. For the available (unused) SPI interface pins look for A2, D11, D12 & D13. These are the NSS, MOSI, MISO and SCK SPI pins respectively. With these available SPI and I2C ports ensure that when you are interfacing to a sensor shield that these ports are initialized properly with the example code for a particular shield.

Since the NAMote72 platform has many included sensor interfaces hopefully these interfaces will be enough for a LoRa evaluation and development application. In early 2016 there are some resources opening up to include some examples on interfacing to the included Arduino headers on the NAMote72 platform. If you have interest in a particular shield to test first then let us know. Thanks, Loren
