IIOD demo is a standard example, provided in most no-OS projects, that launches a IIOD server on the board so that the user may connect to it via an IIO client. Using iio-oscilloscope, the user can configure the DAC and view the ADC data on a plot.
To build the IIOD demo, add the following flag when invoking make which will build the IIOD server and the IIO section of the driver.
To run the IIOD demo, first connect to the board via UART to see the runtime output messages with the following settings:
Baud Rate: 115200bps Data: 8 bit Parity: None Stop bits: 1 bit Flow Control: none
Please note that for proper message display, you may need to convert all LF characters to CRLF, if your serial terminal supports it.
With a serial terminal correctly configured and listening to incoming messages, launch the application (
make run or click the debug button in your SDK). Runtime messages specific to the application will apear on your serial terminal screen, and eventually the following message is printed:
Running IIOD server... If successful, you may connect an IIO client application by: 1. Disconnecting the serial terminal you use to view this message. 2. Connecting the IIO client application using the serial backend configured as shown: Baudrate: 921600 Data size: 8 bits Parity: none Stop bits: 1 Flow control: none
This message implies a IIOD server is being run and you may connect to it using a serial-backend enabled iio-oscilloscope and with the settings indicated at the serial terminal.
