Enable the D0 GPIO

This step enables the GPIO input pin. It is a required step for reading its value or activating notifications.

• create a flow which issues:

  • an HTTP PUT request
  • to URL http://127.0.0.1:8080/api/v1/oap/{{mote}}/digital_in/D0

  • with payload

    {
        sampleCount: 1,
        rate: 10000,
        enable: 1,
        dataFormat: 0
    } 

• Open the SmartMesh IP Tools Guide (http://www.linear.com/docs/42453), looks for section "/digital_in". What does dataFormat 0 mean? 
  

  Answer 1:

  
  

Read the value of the D0 GPIO

• create a flow which issues:

  • an HTTP GET request
  • to URL http://127.0.0.1:8080/api/v1/oap/{{mote}}/digital_in/D0
• Issue the command to your mote

• What is the state (value) of your pin?

  Answer 2:

  
  

• Connect a jumper between the DP2 and VSUPPLY pins. Make sure you can read the value of digital_in/D0 to be high.

• Connect a jumper between the DP2 and GND pins. Make sure you can read the value of digital_in/D0 to be low.
  

  NEVER CONNECT VSUPPLY AND GND TOGETHER!!
