Hi, unfortunately I hadn’t received the previous notifications. I’m not an expert on this module, so I don’t know whether the headphone HAT version is compatible.
In any case, error 7789 should disappear after restarting the Raspberry Pi Zero.
It should be enough to simply install the plugin, wait for the process to complete 100% (it may take some time), enable it, and then reboot. If it’s necessary to change the pin setting, the Raspberry Pi should always be restarted.
I don’t think it works on the latest version of Volumio 4. I’m going to have to try and flash 3 and see what happens but I know this zero 2 and this hat work, and the display powers, but the installation of 7789 or whatever fails and I cannot get it to install.
I just tested the plugin installation on a clean installation of Volumio 4 and I’m encountering something wrong with the installation of the st7789 module.
For some reason, the installation script no longer works as expected.
I will investigate the issue and release an update as soon as possible!
