Hello,

I noticed a NS4168 chip in the Circuit Schematic Diagram.

Could you add an example which explains how to use the CrowPanel ESP32 Display 7.0-inch speaker interface?

Is the speaker output of the 7" Advance HMI intended for connection of a standard 4/8 ohm speaker, or something else?

Crowpanel 7" twitching screen when sound played with speaker

atrus2905 — Tue, 17 Sep 2024 18:17:33 +0000

Hello,
I am using a Crowpanel 7" with a speaker connected on the SPK port.
I noticed that when a sound is being played on the speaker (using the library ESP32-audioI2S-master, following the tutorial on https://www.elecrow.com/wiki/ESP32_Display_7.0-inch_HMI_Arduino_Tutorial.html#example2-play-music), the displayed screen twitches from left to right, like there is noise on it.
Is it an issue known to you, and if so, do you have a solution on how to solve this, please?
Have a great day,

Mehdi

Compatibility between Crowpanel 7.0 and Crowtail-Speaker

Hello,
Is it possible to plug the Crowtail Speaker on the Crowpanel 7.0 to play sounds? If so, on which connector? If not, is there a product on Elecrow that could go on the SPK port of the Crowpanel?
Have a great day,

Mehdi
