Missed button presses when using a spi LCD screen

ESPHome
1

I’m struggling with something that should be simple in principle.
I simplified my project to a simple lcd screen (spi ILI9488_A), binary sensor (gpio input), rotary encoder and a switch (gpio output).
I’ve noticed that when the lcd writes a lot of information like a simple filled rectangle many button presses are lost (for backlight on/off, unusable) but not the encoder pulses.
I’m trying to find to activate an interrupt for the gpio input but I can’t find anything similar in configuration.
No lcd settings improve this behavior like data rate, update interval or auto clear.
I understant that the encoder works with interrupts, so I suppose that something similar could be able for gpio?
Any tips? Thanks!

Display ILI9488_A SPI

Or some of the numerous peripherals Esp32 has. Idea is same.
But afaik, theres no way to use interrupts for binary sensor.

Post your yaml and esphome logs.

Thanks for your reply

The log doesn’t present the situation where Esp is “blocked”.
Try with debug if you can get some useful info like loop time.

I can’t see nothing except a high loop time.
I can try to force the CPU speed to 240Mhz but I think this is not the problem. Misses 3 or 4 button push each 5.

That’s enough to explain your problem with binary sensor. Ideally loop time should be <20ms vs yours 500-1000ms.
But I can’t see the reason for that on your log. Display doesn’t even have one line there…

7

The update interval of 250ms on the display won’t help, especially since you’re redrawing the whole screen every update, and the ILI9488 is a particularly slow display. Basically you are using the entire CPU time just writing to the display.

You would be better off using LVGL which will only redraw what changes, and only as required.

8

I’m aware that SPI LCD are slow, in fact I’m using 2 screens (not in this simplified example). But the update interval is not important for me, all the sensors are updated every 10 seconds and the screen information every 1s.
All works well including the rotary encoder to navigate between pages except the button to turn off and on the backlight. It is awkward not having the possibility to use interrupts in gpio for that simple thing…
I didn’t know about the existence of the LVGL library!, I thought there is no such thing in ESPhome, I will try!. Thanks!
BTW I guess I’ll eventually swap out the screens or improvise a timer wit the rotary encoder to turn on the backlight.

Thanks for the responses!

I’m checking the LVGL documentation and seems do not have support for animated gifs.
In my device I only use a small wave animated gif to show the water level and a value in percent, for that reason I swap to a N16R8.
I will keep the LVGL documentation for future projects because is really nice.

I agree.
Try with pulse_counter total. Use on_value to get trigger.
Never tried, but might work. Pulse counter uses PCNT peripheral.

Nice! I didn’t expect this could be a widget. Let’s try it.
Thanks!

13

BTW this work like a charm:
Check the value each second and then switch it.

  - platform: pulse_counter
    pin:
      number: GPIO08
      inverted: true
      mode:
        input: true
        pullup: true
    name: "Encoder button"
    count_mode: 
      rising_edge: DISABLE
      falling_edge: INCREMENT
    use_pcnt: True
    update_interval: 1s
    on_value_range: 
      above: 1
      then:
        - switch.toggle: lcd1_led
14

Nice, now you have your “interrupt button”.
Try to work on display anyway, 1s loop time is not preferable in any case.
