 There are also options that communicate using I2C. These will use connectors I2C0 and I2C1 as shown. Commonly these will offer improved resolution e.g. 16 bits so 65536 levels. They may also offer amplifiers, multiplexers or other enhanced functionality.

+This particular VI uses the M5Stack DAC2 and this gives us 2 channels of 16 bit Analog Output. Select the port for the connected Pico and the Grove connector that the board is plugged into. Press the run arrow.
 
-This particular VI uses the dual buttons. Select the port for the connected Pico and the Grove connector that the board is plugged into. Press the run arrow.
 
-You should now see the button indicators light up when the corresponding button is pressed. The Indicators use a transparent fill for the off state and a brighter Red or Green for the on state.
 
-Links to various other similar boards are also on the Front Panel.

-On the block diagram you can see that the selected Grove connector dictates the GPIO Pin and we then set the pin to [In]. Next we loop round and event structure and use the timeout to poll the digital inputs. Pressing Stop will fire the Stop event and exit the loop.
+On the block diagram you can see that the selected Grove connector dictates the GPIO Pin for the IC2 Port. We set up the IC2 port for the device in **Init.vi**. Next we loop round the event structure and wait for a Sliders V0 or V1 to be changed. When change has been detected the new values are input into the **Write DAC.vi**.  Pressing Stop will fire the Stop event and exit the loop.
