Access CCpilot VI2 Hardware Buttons and Buzzer from CODESYS

Access CCpilot VI2 Hardware Buttons and Buzzer from CODESYS

This CODESYS application example shows how the state of the hardware buttons and the buzzer on the CCpilot VI2 display can be read and used in the application.

Run on VI2

 

There are four squares for ech of the buttons and when a button is pressed, the square next to the button changes the color to pink. Then there is also a "Buzz button" that activates the buzzer and you will hear a buzzer sound for as long as you hold the button pressed.

The project uses the CCAux API interface to handle the states of the buttons and the buzzer. The state is then available from the GUI. The project example also includes a basic example of the buzzer functionality as previously described.

Visualization from CODESYS IDE

You can see in the impementation that functions such as:

About_GetNrOfButtons, SoftKey_GetStatus

Buzzer_SetVolume, Buzzer_SetFrequency, Buzzer_GetTrigger & Buzzer_SetTrigger

are used from CCAux in order to get access to buttons and the buzzer.
