Hi I'm using TM4C1230C3PM processor and I want to buzz the buzzer when the button is pressed.

FYI, here's the code I tried.

Thanks.

Hello Sukgyu,

Please refer to the post below for PD7.

The buzzer requires a periodic signal so I am not sure if just making the Pin low or high would be sufficient.

thank you for the quick response! I'll try to unlock the pin!

Oh, once the buzzer works, is there any way to control the tone of the buzzer using the clock speed?

Hello Sukgyu

You can select a Timer to generate a PWM output (in audible range) which can then be used to control the buzzer. In the If condition you would be enabling or disabling the IO function or the timer.
