Add support for buzzer

[xtimmy86x]

Hello, i'm using this project with a arduitouch that have a integrated buzzer connected to a GPIO of the esp32 board

It's very interesting if it will be integrated and controllable with the home assistant integration

Add it as a switch.

i did it but no sound, only a soft crackling sound when i put on and off the switch

You need to drive the pitch/length via a library. Take a look at the documentation on how to add your custom code.
Make sure that the code is non-blocking or it will interfere with the performance of the UI and other compoments.

You're talking about a piezo speaker, not a buzzer. Likely you picked the wrong part.

A buzzer is able to output a sound (predefined from factory) when some DC is applied to its terminals.

A piezo speaker is just a part of the buzzer. It needs some audio signal to be generated and applied to it to act like a buzzer. Openhasp doesn't support that.

I would be interested to add such buzzer to my screens so that I get a heptic feedback when touching the screen. This could also be a coin vibration motor. Is there a way to control such GPIO output directly on the device or I need to send an MQTT command to control a GPIO output?

You can check out feedback_cb in lv_indev_drv_t, which facilitates playing a sound on LV_EVENT_CLICK. This should also make it possible to vibrate a motor.

Wow, this would worth to be exposed to UI, to be used in a "group" with a GPO pin...

I see this is an old discussion, but can't find anything newer.
Did something change in the last year? Maybe RTTTL support (that fits quite nicely in a MQTT message...)?

add librrary , eg. ezBuzzer

Acoustic feedback is very useful for touch input. It is sorely lacking in OpenHASP!
Otherwise it's really good for various small touch displays in conjunction with Homeassistant or other MQTT environments. The programming implementation is great.
