I cannot seem to get the Waveshare 4.3 ESP32 touch display to display anything. I am using the RPI_DPI_RGB driver using the provided settings for Waveshare. I have this display working fine under VS Code and have double checked the pin configuration for that and they are identical as that in ESPHome YAML.
I originally had LVGL and the touch configured but for diagnostics stripped it down to bare minimum. So the code above the “display” section is vanilla config with the exception I changed the platform type from arduino to esp-idf. It uploads, i can visit the device’s web page. It just doesn’t seem to do anything with the display.
I assume the Lambda function would display something after display setup. I’m really new to ESPHome so I could be doing something silly. I’ve attached the YAML I used.
Help ?

Ok, I found an example on this thread from @Jon_2232 :
After a few flashes/toying with settings I was able to get it to stop flickering too, at least with the RGB BW fill in Real.Problems post.
Tried adding image or graph display components and maybe I missed having to add an include or something for it?
Linking .pioenvs/waveshare44/firmware.elf
/data/cache/platformio/packages/[email protected] +2021r2-patch5/bin/../lib/gcc/xtensa-esp32s3-elf/8.4.0/../../../../xtensa-esp32s3-elf/bin/ld: .pioenvs/waveshare44/src/esphome/components/disp…
I couldn’t get it to compile initially. The item that seem to give a display was:
psram:
mode: octal
speed: 80MHz
But I had a lot of corruption and the synch didnt seem to be quite right. I think the corruption was probably due to where ever memory was being used wasnt a great place.
I used my timing settings and then folded in Jon’s code and got it to compile and it is displaying his clock demo.
This is what my code looks like now:

It’s basically Jon’s code, I dont know if I return the timings to his it would be any different. Anyhow, I consider this solved.

Thanks Andrew, I’ve added those settings in.
Out of interest do you have issues with doing wifi updates? It seems really slow, so slow that it disconnects, or its really fast. I often have to do reboot it just before I’m about to upload.
I’ve even had to resort to putting the board back to initial settings. It’s as if when running it cant process the connection.

I don’t have one of those screens. But I do have the a similar screen (sunton-esp32-8048s070) and I don’t have issues with upgrades.

I have heard of some of these screens sharing the Wi-Fi pin with other hardware. This causes lot’s of issues with Wi-Fi updates. In this case you may have to update via USB.
You may want to look into using a different screen.

Using ESP-IDF 5.3 will fix that. There is new code in ESPHome to take advantage of a better display driver - it’s in the dev branch, not sure if it made it into the latest release.

So it now sees the Flash as 8MB.
But, I still get the same error.
I’m wondering if this is related to this: How to increase partition size (to use 16MB of flash instead of 4MB)

That’s not the correct syntax (refer to the docs) but unless you have multiple displays, you don’t need the displays: key at all.
