Hi everyone,
I am trying to configure this waveshare display (1024x600) 5inch with esphome but I can’t find out the right display declaration (driver) to use.
Any advice?
If u need I can provide the link to the tech spcecification
Thank you
Matteo
That would be helpful, probably necessary.
Here the link to the product:
Here the link to the waveshare wiki:
Ps: I owned the 1024 x 600 one
Thank you very much in advance for any help

Matteo
Looks to be similar to the 4.3 board in configuration. There are topics here discussing it.
In the wiki it points to the ST7262 datasheet so I guess that is what it has.
Hi there,
Thank you very much for the support.
Right now I was able to validate the configuration of most of the code verifying all the pins and other stuff in the tech documentation of the product. What I was not able to find is the PIN about the backlight. For the CrowPanel 5.0" HMI ESP32 display (by Elecrow) I find this snippet code:
psram:
mode: octal
speed: 80MHz
output:
- platform: ledc
pin: 2
frequency: 1220
id: gpio_backlight_pwm
light:
- platform: monochromatic
output: gpio_backlight_pwm
name: Display Backlight
id: back_light
restore_mode: ALWAYS_ON
I have a lot of doubt about the Pin, probably is not 2 and about the others parameters.
Could you please help?
Thank You in advance
Regards
The backlight will be the DISP pin in the I/O table - pin 2 on the CH422 expander. It won’t be usable with PWM so you’ll just have to use a binary light.
Thank you for the support. Clear for the pin.
I don’t know what to do with the code. Is it right in that way? I mean the one in my previous post.
Thanks
Hello,
I want to ask you if you got it working.
Thanks in advance!
Hello,
yes. I do.
Matteo
Hello, could you please share the code? I’m having trouble configuring it. I have a version with 1024x600 pixels. I can get the screen to work without touch functionality or the touch to work without the display. Your help would be greatly appreciated!
@Arkady0 or @Scarpetta3
I have got the same display, brought it accidently should of got one that was better supported by ESPhome. Would you be able to share your YAML as this is my first time and I haven’t been able to get it to work?
@Arkady0 @bryce-evenden
I bought one of those, also in the hopes that ESPHome would support it out of the box, and in fact it almost does. The changes required to the configs that work for the supported boards are not that huge and I have put the version that works for me on Codeberg.
Compared to the config I started out with one or two of the EXIO pins were different but the most relevant part was the pixel clock and the vsync/hsync timings. The key to getting those right was just looking at the Waveshare-provided demo code in “waveshare_rgb_lcd_port.c” that had all the relevant numbers.
I haven’t done any in-depth testing yet but this config shows the lvgl demo page without a hitch and correctly reads the touchscreen, so I’m not really expecting any significant problems.
I don’t use ESPHome all that much and the fact that I combine the devices with OpenHAB and not Home Assistant likely makes me the odd duck out, but if anyone has any pointers on where to start/read up I’m willing to try to polish this to the extent that it could be added to esphome as a supported board/display model/whatever is appropriate.
Hello,
sorry for my late reply but it’s a very busy time for me.

Not sure what you mean by validate, but you can delete everything in the display config after the model line - see the example in the PR comment.
Thank You very much for your answer!! Everything is clear and it’s working great!
If possible, I’d like to take advantage of your kindly availability for some more questions about this piece of hardware.
- I want to power the display through the connectors. From the specifications, I understand that I can do so using terminals 13 (ref. figure) with a voltage of 12 V. Is that correct?
- I’d like to power an ESP-32 Dev Kit C V2 board with a 5 V operating voltage through the display. I understand this can be done using terminals 14 (VOUT and GND, ref. figure). Is that correct?
- I understand that VOUT is set to 3.3 V by default. How can I change it to 5 V using switch 20 (ref. figure)? Do I need to solder?
- I’d like to complete a circuit without voltage or current that has the sole purpose of controlling the operation of a heat pump. It seems to me that this can be done with terminals 18 and 19 (ref. figure) by connecting them as in the digital input dry contact diagram (ref. figure). Is that correct?
Thank You very much
Regards
Matteo
I figured I’d jump in here as I’m currently using the ESP32-S3-Touch-LCD 5B to make a smart thermostat with ESPHome. With the help of this thread and other similar ones I’ve gotten the screen connected to ESPHome, the backlight turning on and off and some basic LVGL buttons and widgets functioning. The last thing I need to figure out is the best way to turn on & off the boiler which only requires to close a low voltage (24v) switch. In the past I’ve accomplished this with an ESP32 GPIO and a relay. I’m not against doing it that way again but I’m having issues on finding solid info on what pins to use. I’m having a hard time reading the schematics. Any solid info on what pins to use would be greatly appreciated.
Possibly I could also go the DI/DO route talked about in point 4 of Scarpetta3’s post but again I’m not fully understanding how this is implemented. If this could be explained it would be appreciated.
Thanks
