Touch example resets/black screen

[webworxshop]

Hello,

I'm having trouble using the touch example. As a precursor, I tried the LCD only example, which works perfectly.

When the board powers up on the touch example, I get the following in the logs several times (and nothing else):

WARNING Decoded 0x42095aba: esp_pm_impl_waiti at /Users/ficeto/Desktop/ESP32/ESP32S2/esp-idf-public/components/esp_pm/pm_impl.c:839

This looks to me like the board is resetting a few times, but this stops after a few cycles. The board then sits there with a blank screen and is offline in Home Assistant. The red LED flickers (as with the LCD only example).

If it's any help, my board has the text "T_Display_S3 22-8-2 V12" on the back. Perhaps a different/newer version?

Please let me know of any more info I can provide to get this working.

Thanks in advance,

Rob

OK, I managed to make some progress, I needed to specify deassert_rts_dtr: true to get the logging working correctly.

The device seems to be boot looping a few times and then starts up and connects to the wifi:

The device is then, in fact, pingable on that IP:

So esphome is at least running (unexplained initial bootlooping aside). The screen is still blank however and no touch events are logged, so it looks like the display and touchscreen driver are conflicting somehow?

I did suspect that this may be a power issue so I plugged the board into a 4.8A USB power supply, which gave the same result (device pingable, no display, no touch events logged).

[landonr]

thanks for posting your findings. I don't have a touch device but maybe @guillempages has an idea

[guillempages]

I have the same text on the board (so I assume we have the same HW version), and I can also reproduce the issue with the latest master branch. Moving back to some older commit is working again, so this must be something introduced lately.

I'll try to find out what the problem might be and do a PR accordingly.

[guillempages]

Looks like it is an issue with PS-RAM. On the PR by @Fabian-Schmidt, he changed the tft and spr members to be pointers; allocated dynamically on setup(). If I change them back to plain variables, it's working again for me.

Fabian, do you have the touch version or the non-touch version of the T-Display-S3? There might be a difference on how the psram is configured/used if touch is there. At least, I haven't been able to use psram at all on my device.

[guillempages]

nope, not psram. I managed to get psram working (with the extra platformio options that Fabian helpfully added to the examples), but with the dynamically allocated tft and spi variables it's still crashing.

[guillempages]

PR #34 should fix the issue. @webworxshop, can you test if it fixes it for you as well?

[Fabian-Schmidt]

I don't have a touchscreen. The change to allocate in setup was due to minimize allocation during object creation to avoid OTA issues. ESP Home likes to create as little as possible in object creation and moves most to setup method.

[webworxshop]

@guillempages I can confirm that your PR is working for me, in that the display is now running.

For some reason I'm not getting anything logged on touch events using the lambda in the example, but maybe I need to poke around with the logging more to get that working.

Thanks for the awesome work!

[guillempages]

The change to allocate in setup was due to minimize allocation during object creation to avoid OTA issues. ESP Home likes to create as little as possible in object creation and moves most to setup method.

That's a good goal. I just changed the allocation of the tft object, but left the sprite allocation in the setup method. Otherwise it is not working for me; I cannot explain why :-(

@webworxshop I'll need to look at the touch issue some other time; it's now time to go to bed ;-) Let me/us know if you manage to get it working though. I'm not logging anything on touch, but have setup some binary sensors with platform touchscreen, and they work like a charm for me.

[guillempages]

I think I have an idea why is crashing when initializing in setup. IIRC the touchscreen component is getting the height and width from the display component, and this two methods are calling the tft pointer. So initializing it on setup is probably to late.

I'll have to do some checks tomorrow to confirm that.

[circuit69]

I have the touch screen version and have been having these same issues. Working fine until I add the code for the touchscreen. Once this is working again I hope to incorporate the touch function into HA. I'm still new to all of this stuff but looking forward to learning how it can be used.

Thank you for all your work.

[webworxshop]

@guillempages Sorry to post on a now closed issue, but I just wanted to confirm that I did get the touchscreen logging working using the esphome logger.log action.

Thanks again for all your help.
