ZigBee DIOs and ADCs example for mbed XBeeLib By Digi
This example shows how to handle remote XBee module's DigitalInputOutputs and ADCs. The example configures the remote XBee module pins to the desired functionality and then operates on the state of the pins themselves.
See Handling remote modules DIOs ADCs and PWMs chapter for more information.
Common Setup
Make sure you have a valid Example Common Setup
Example Setup
Application
You have to configure the remote device 64-bit address by customizing the REMOTE_NODE_ADDR64_MSB and REMOTE_NODE_ADDR64_LSB defines with the remote XBee module 64-bit address.
Hardware
On the Remote XBee module, wire following peripherals on the pins specified on the table and schematics or change the application pins according to your hardware setup:
| Line | Pin | Value |
|---|---|---|
| DIO2/ADC2 | 18 | ADC (Analog Input) |
| DIO3/ADC3 | 17 | Digital Input |
| DIO4 | 11 | Digital Output |
Running the example
Build and deploy the example to the mbed module.
Reset the mbed module so the example starts. You should see the example debug information through the debug interface configured in the 'Local Setup' chapter.
Once joined to the coordinator, the application will do following operations:
- Configure the remote XBee module pins according to the table above.
- Do following loop every 5 seconds:
- Read DIO3_AD3 digital value
- Toggle LED associated to DIO4
- Read DIO2_AD2 analog value
