Compared to 4848S040, it has added a microphone and magnetic QI wireless power supply, but uses the screen of st77916 QSPI. I have installed ESPHome, but I can control the backlight because the screen is not within ESPHome’s support range and I cannot make the screen work.
If it is supported by ESPHome, that would be great
-CNC casing
-The price is about $20
That is a really nice looking screen. My guess it more screens will start using this chip. Another user has requested a ESPhome driver for it.
Quad SPI AMOLED Displays — ESPHome

Unfortunately, ESPHome does not have the QSPI-LCD component. Looking forward to adding it
There is no difference - the QSPI will work with either. The display driver does need to be ported.
I hope someone can contribute a driver program set
Can anybody put together a basic configuration based on what is known?
The issue is no ESPhome component for the display driver IC yet
ESPHome has QSPI BUS and adds two AMOLED display models. There is no LCD display model.
The QSPI bus can be defined as “quad” in the spi component and is separate from any display, at least I have used it to talk to a LCD display. The display driver for this LCD is what’s missing.
Yeah the code is here but my C skills are not good enough. Does anybody have the skills to take a wack at adding this to ESPHome?
Its now natively supported by ESPhome component in DEV version 
Thanks to Clyde for updating the QSPI to accept custom init code and renaming it.

I acquired this Waveshare device, and it looks very similar:
However, I’ve had no luck using Clyde’s code for the screen. Am I off base here, or is there something beyond the ports that would need updating?
Thanks for any help.
That is a very different screen from a different manufacture. It does look like it has ST77916 display like the JC3636W518 but it’s on different pins.
Waveshare is good they give you all the pinout info right on the product page so you don’t need to go digging around the internet to find how everything is hooked up.
Well thanks. I wasn’t trying to hijack this thread, but this is the closest equivalent I could find with a working sample.
I presume by “ports” you mean the GPIO assignments.
So yes, in addition you will probably need a custom init sequence, which you would get by looking at the Waveshare demo code and converting to YAML.
You need to configure the correct display and touch GPIO in ESPHome
Then try custom init sequence and finally make it work. As Clyde said, you need to find these from the supplier’s example code. 3636W518 is the init sequence found in this way
Thanks guys. Still no luck. I started a new thread here: Waveshare ESP32-S3-LCD-1.85
I’m fiddling with voice assistant on this device.
I see that the mic is detecting my commands.
But when it try to play the response, there is no sound:

Anyone gotten the speaker to work on this one?
What kind of speaker are you using? You need a speaker with an external amplifier. Otherwise, the sound will be very low.
