AAC20 - LCD - Problem with editing setpoint value from LCD

Issue

After adding to LCD the register responsible for the setpoint value, there is a problem with editing it, and the value is not saved after restarting iSMA-B-AAC20.

Possible cause and solution

Incorrect configuration of the NumericLine component slots or the LinkSet function is not in use.

Solution

• Install the iSMA_LCD kit using the Kit Manager.

• After installation, add the Display component from the iSMA_LCD palette under Drivers in the application.

• Next, add the NumericLine component under the Display component.

• The NVNumericWritable component, which acts as a setpoint, has to be linked with the NumercLine component (link from the Out slot to the In slot).

• Then, configure the NumericLine component slots:

  • Suffix: text displayed left to the component’s value on the LCD, for example, ‘My setpoint’;

  • Editable: set to true.

• The above steps allow to edit the setpoint’s value on the LCD screen for the NVNumericWritable component, which represent the setpoint value.
