piezo - BUZZ |
|
CN2 is a pin connector where the centre pin (2) is connected to a 30V FET
switching to 0V with maximum 200mA.
Users can attach a piezo sounder with integrated oscillator or similar low ripple device to provide an
audible output or drive an LED indicator.
The negative terminal of the device should be connected to the TFT and the
positive to a supply from 5V to 24VDC.
Use the reserved interface word BUZZ to control the output.
LOAD(BUZZ,ON);
LOAD(BUZZ,OFF);
LOAD(BUZZ,500); //sounds for 500ms - half a second.
LOAD(BUZZ,varBuzz); // varBuzz is a user declared variable with a
duration variable.

The Blue field allows you to make simple buzzer test. You can assign time (from 100-1700 ms) using the horizontal slider. To start the simple buzzer test click the blue speaker icon.
The Green field allows you to make a sequence test using a loop. You can set how many times the loop runs using the red slider (from 1 -10).
You have also four variables and you can assign the time (from 100-1000 ms) to each of them using the green vertical sliders. By using the green buttons you can enable (red) or disable (green) the buzzer. To start the sequence test click the green speaker icon.
