Development

Mote Runner:

General / GPIO

This is the development section of the Waspmote Mote Runner platform. You can navigate through the examples with the left bar.

If you actually want to see examples about the original Waspmote platform, please go its specific development section.

» MR-General 01: GPIO Example

This example shows how general purpose input and ouput works on Mote Runner. It makes a write and then it reads the same pin, printing it into screen.

Required Materials

1 x Waspmote PRO
1 x MiniUSB wire
1 x Battery

Notes

* Please, note that the output is in Hexadecimal
* Remember to connect the battery to Waspmote for proper operation.
* To compile this example: mrc --assembly=gpio-1.0 --system=waspmote --ref=logger-#.# GPIOExample.java
