FX30 Digitial Outputs

Now that you've decided to connect to your FX30 via digital output, you'll need to:

1. Take a look at the FX30 pin map and decide which pins you'll use.
2. Wire up the pin.
3. Configure the pins via the GPIO Service in Octave.

This tutorial describes how to configure a output pin on the FX30.

Locating the Appropriate pin map

Review the Rear Port Pinout for the FX30 and identify the output pin you would like to use.

Configuring a Digit Output

The subsections below describe how to add and configure a digital output on your FX30.

Adding a Digital Output

Follow the steps below to configure a digital output pin:

1. Navigate to Device > Services, locate the GPIO section, and click Configure.
2. Locate the Add pin section.
3. Click the Pin drop down and select a digital output pin (e.g. EXT_IO3_DO). Note the expected voltage indicated for the pin which will be 1800mV.
4. (Optional) Change the name in the Resource Path to a more descriptive name.
5. Click Add. The configured output pin appears in the list of GPIO Services.

Setting the Output Value

Follow the steps below to set the value for the digital output pin:

1. Navigate to Device > Resources.
2. Locate and expand io.
3. Locate the resource corresponding to the output pin configured in the previous section The name will be postfixed with /value (e.g. EXT_IO3_DO/value).
4. Click the Configured value column and set the value to true.

The GPIO pin should now be producing a voltage of 1800mV.
