Installing ESPhome on GEEKMAGIC Smart Weather Clock (smalltv/pro)

Yes the flickering is coming from the missing frame buffer…

Without frame buffer each time the display needs to be updated we have to load the entire screen memory with blank, then let the lambda update the screen memory with the content we want to display and write this content for each and every pixel in the memory screen.
The flickering is coming from the those 2 sequential write screen operations and the delay in between …
With frame buffer there is one single write operation to the screen…

To reduce flickering you can specify different ‘update_interval’ value (default is 5s) in the display configuration and/or request the update only on demand from another component with component.update: my_display or lambda 'lambda: ‘id(disp).update();’

22

Ah, i see. Thanks for the explanation.

There seems to be no option to disable the update_interval. So setting a very high amount of seconds does the trick.

23

Refresh can be disabled using

update_interval: never

24

Oooops, you’re right. Thanks again!

Do you want to send a pull request to the ESPhome project?

Yes I’ll share this, but in two different proposals.

The no CS pin with spi mode change will be useful for other hwd implementations and no compatibility or performance concerns .

But the no frame buffer implementation a bit more questionable since its performance is not optimal…

Hello everyone,

Just received today a pro version. In case it could be useful, I performed some probing to identify the signals.

The programming connector has same assignment.

For tbe screen the signals are:
DC: gpio02
Sck: gpio18
Mosi: gpio23
Rst: gpio14
Backlight: gpio25

Cs is tight to gnd meaning we’ll have to SPI mode 3 as well to get it working.
Think the previously shared fork of the driver should work. I’ll give a trial tomorrow now…

The touch button is mapped on gpio32

[edit] Pins assignment confirmed as well as functionality with forked drivers. Since heap since is huge on ESP32, frame buffer is kept activated by default and no flickering effect…

FYI, PR raised here for SPI mode fix st7789 using mode3 when no cs pin by rletendu · Pull Request #5541 · esphome/esphome · GitHub

Great, thanks! :+1:

My plus arrived today. Will update any progress.

I received my Pro today, any further progress on this topic guys ?

31

Mine is just sitting on my desk telling me the time.

32

The pro is working fine on my side. The amount of memory available on this one makes it more confortable. I use it as a small monitor to display on different pages (weather forecast, temperature graph, mailbox…) some key information from my HA.

That’s really cool, I was searching for how can I do something similar, Do you mind sharing your ESPHome config file for your setup !!

34

Implementation is really tied to your HA entities, but In case it could serve your inspiration, here’s what I end up with

Note the native display page feature of ESP Home is not working on this display type. had to rebuild it manually

Hello! Interesting topic! :star_struck:
I ask for a feature request which it can be helpful and funny as well. Please have a look and if you find it interesting or you have better suggestions please to vote or add a comment. :wink:

Well you don’t need that now do you. Just use esphome

Answered my own question: see below.

How are you guys flashing these devices? I have SmallTV Pro (so the esp32 device). When I plug it into USB of the esphome server (a linux x86 box) or into my windows laptop it doesn’t seem to register a serial device. (Using the same cable etc I can see other devices).

Do I perhaps have to disassemble it and plug a flasher device in? I haven’t had to do that in a while. Or perhaps the original firmware can upload an esphome firmware vis OTA in some fashion?

Tips appreciated :slight_smile:

Here is how - if you compile the firmware on esphome and download the bin file in legacy format it can be flashed using the inbuilt firmware updater on the SmallTV Pro.

Just a heads up on @rletendu’s code for the display. I have been playing around over the last couple of days using esphome 2023.12.5 and home assistant 2024.1.0b3 (yes the dreaded beta test version).

esphome 2023.12.5 does not seem to work on @rletendu’s github code, and after reading this PR st7789 using mode3 when no cs pin by rletendu · Pull Request #5541 · esphome/esphome · GitHub I realised that the spi change should be done in the config of the st7789v component in your esphome yaml. In other words, take out the external_component code from what @rletendu’s config in Post 34 above and use this in the display code

display:
  - platform: st7789v
    model: "Custom"
    spi_id: spihwd
    height: 240
    width: 240
    offset_height: 0
    offset_width: 0
    dc_pin: GPIO02
    reset_pin: GPIO04
    #backlight_pin: GPIO25
    eightbitcolor: True
    #update_interval: never
    update_interval: 5s
    id: disp
    spi_mode: mode3

The change is the last line spi_mode: mode3

Hope that helps someone, my device now at least says “Hello World” :slight_smile:

PS no detraction from @rletendu’s work, he worked out the problems and did all the work. I think esphome changed the rules of engagement :slight_smile:

Hello, sorry for my english. Have you the good code for use this module with this screen ?
Thank you

Read the thread, he posted the code, but also see my recent updating post.
